This book is not written especially for geologists or other scientists
as such, though it deals with the question which it discusses from a purely
scientific standpoint, and presupposes a good general knowledge of the rocks
and of current theories. It is addressed rather to that large class of readers
to whom geology is only an incident in larger problems, and who are not
quite wholly satisfied with those explanations of the universe which are
now commonly accepted on the testimony of biological science. I am free
to say that my own conviction of the higher value and surer truth of other
data outside of the biological sciences have always been given formative
power in my own private opinions, and that in this way I have long held
that there must be something wrong with the Evolution Theory, and also
that there must be a surer way of gauging the value of that Theory, even
from the scientific standpoint, than the long devious processes connected
with Darwinism and biology. Some years ago, when compelled to investigate
the subject more fully than I had hitherto done, I discovered, somewhat
to my own surprise, the phenomenal weakness of the geological argument.
The results of that investigation have grown into the present work.
Though mostly critical and analytic, it is not wholly so. But so far as
it is constructive there is one virtue which can rightly be claimed for it.
It is at least an honest effort to study the foundation facts of geology from
the inductive may be standpoint, and whether or not I have succeeded in this, it
is, so far as I know, the only work published in the English or any other
language which does not treat the science of geology more or less as a
cosmogony.
That such a statement is possible is, I think, my chief justification in
giving it to the public. It would seem as if the twentieth century could
afford at least one book built up from the present, instead of being postulated
from the past.

A brief outline of the argument which I have used in the following pages
will be in order here.
Darwinism, as a part, the chief part, of the general Evolution Theory,
rests logically and historically on the succession of life idea as taught by
geology. If there has actually been this succession of life on the globe, then
some form of genetic connection between these successive types is the intuitive
conclusion of every thinking mind. But if there is no positive
evidence that certain types are essentially older than others, if this succession
of life is not an actual scientific fact, then Darwinism or any other
form of evolution has no more scientific value than the vagaries of the old
Greeks—in short, from the standpoint of true inductive science it is a most
gigantic hoax, historically scarce second to the Ptolemaic astronomy.
In Part One I have examined critically this succession of life theory.
It is improper to speak of my argument as destructive, for there never was
any real constructive argument to be thus destroyed. It is essentially an
exposure, and I am willing to give a thousand dollars to any one who will,
in the face of the facts here presented, show me how to prove that one kind
of fossil is older than another.
In Part Two I have attempted to build up a true, safe induction in the
candid, unprejudiced spirit of a coroner called upon to hold a post mortem.
The abnormal character of most of the fossiliferous deposits, the sudden
world-wide change of climate they record, the marked degeneration in all
organic forms in passing from the older to the modern world, together with
the great outstanding fact that human beings, with thousands of other
living species of animals and plants have at this great world-crisis left
their fossils in the rocks all over the world, prove beyond a possible doubt
that our once magnificently stocked world met with a tremendous catastrophe
some thousands of years ago, before the dawn of history. As for
the origin of the living beings that existed before that event, we can only
suppose a direct creation, since modern science knows nothing of the spontaneous
generation of life, or of certain types of life having originated before
other types, and thus being able to serve as the source of origin of other
alleged succeeding types.
With the myth of a life succession dissipated once and for ever, the
world stands face to face with creation as the direct act of the Infinite God.
How many of us have ever tried to think out a statement of just how
we would prove that there has been a succession of life on the globe in
a particular order?
Herbert Spencer did[1] and he did not seem to think the way in which it
is usually attempted a very praiseworthy example of the methods to be
pursued in natural science.
He starts out with Werner, of Neptunian fame, and shows that the
latter's main idea of the rocks always succeeding one another over the
whole globe like the coats of an onion was "untenable if analyzed," and
"physically absurd," for among other things it is incomprehensible that
these very different kinds of rocks could have been precipitated one after
another by the same "chaotic menstrum."
But he then proceeds to show that the science is "still swayed by the
crude hypotheses it set out with; so that even now, old doctrines that are
abandoned as untenable in theory, continue in practice to mould the ideas
of geologists, and to foster sundry beliefs that are logically indefensible."
Werner had taken for his data the way in which the rocks happened to
occur in "a narrow district of Germany," and had at once jumped to the
conclusion that they must always occur in this relative order over the
entire globe. "Thus on a very incomplete acquaintance with a thousandth
part of the earth's crust, he based a sweeping generalization applying to
the whole of it."
Werner classified the rocks according to their mineral characters, but
when the fossils were taken as the prime test of age, the "original nomenclature
of periods and formations" kept alive the original idea of complete
envelopes encircling the whole globe one outside each other like the coats
of an onion. So that now, instead of Werner's successive ages of sandstone
making or limestone making, and successive suites of these rocks, we have
successive ages of various types of life, with successive systems or "groups
of formations which everywhere succeed each other in a given order; and
are severally everywhere of the same age. Though it may not be asserted
that these successive systems are universal, yet it seems to be tacitly
assumed that they are so.... Though, probably, no competent geologist
would contend that the European classification of strata is applicable
to the globe as a whole; yet most, if not all geologists, write as though it
were so."
Spencer then goes on to show how dogmatic and unscientific it is to
say that when the Carboniferous flora, for example, existed in some localities,
this type of life and this only must have enveloped the world.
"Now this belief," he says, "that geologic 'systems' are universal, is
quite as untenable as the other. It is just as absurd when considered a
priori: and it is equally inconsistent with the facts," for all such systems
of similar life-forms must in olden time have been of merely "local origin,"
just as they are now. In other words, we have no scientific knowledge of a
time in the past when there were not zoological provinces and zones as
there are to-day, one type of life existing in one locality, while another and
totally different type existed somewhere else.
Then, after quoting from Lyell a strong protest against the old fancy
that only certain types of sandstone and marls were made at certain epochs,
he proceeds:
"Nevertheless, while in this and numerous passages of like implication,
Sir C. Lyell protests against the bias here illustrated, he seems himself not
completely free from it. Though he utterly rejects the old hypothesis that
all over the earth the same continuous strata lie upon each other in regular
order, like the coats of an onion, he still writes as though geologic 'systems'
do thus succeed each other. A reader of his 'Manual' would certainly suppose
him to believe, that the Primary epoch ended, and the Secondary epoch commenced,
all over the world at the same time.... Must we not say that
though the onion-coat hypothesis is dead, its spirit is tractable, under a
transcendental form, even in the conclusions of its antagonists."
Spencer then examines at considerable length the kindred idea that
the same or similar species "lived in all parts of the earth at the same time."
"This theory," he says, "is scarcely more tenable than the other."
He then shows how in some localities there are now forming coral deposits,
in some places chalk, and in others beds of Molluscs; while in still other
places entirely different forms of life are existing. In fact, each zone or
depth of the ocean has its particular type of life, just as successive altitudes
do on the sides of a mountain; and it is a dogmatic and arbitrary assumption
to say that such conditions have not existed in the past.
"On our own coasts, the marine remains found a few miles from shore,
in banks where fish congregate, are different from those found close to the
shore, where only littoral species flourish. A large proportion of aquatic
creatures have structures that do not admit of fossilization; while of the
rest, the great majority are destroyed, when dead, by the various kinds of
scavengers that creep among the rocks and weeds. So that no one deposit
near our shores can contain anything like a true representation of the
fauna of the surrounding sea; much less of the co-existing faunas of other
seas in the same latitude; and still less of the faunas of seas in distant
latitudes. Were it not that the assertion seems needful, it would be almost
absurd to say that the organic remains now being buried in the Dogger
Bank can tell us next to nothing about the fish, crustaceans, mollusks, and
corals that are now being buried in the Bay of Bengal."
This author evidently found it difficult to keep within the bounds of
parliamentary language when speaking of the absurd and vicious reasoning
at the very basis of the whole current geological theory; for, unlike the other
physical sciences, the great leading ideas of geology are not generalisations
framed from the whole series or group of observed facts, but are really
abstract statements supposed to be reasonable in themselves, or at the most
very hasty conclusions based on wholly insufficient data, like that of
Werner in his "narrow district of Germany." Sir Henry Howorth[2] has well
expressed the urgent need that there is of a complete reconstruction of
geological theory:
"It is a singular and a notable fact, that while most other branches
of science have emancipated themselves from the trammels of metaphysical
reasoning, the science of geology still remains imprisoned in a priori
theories."
But Huxley[3] also has left us some remarks along the same line which
are almost equally helpful in showing the essential absurdity of the assumption
that when one type of life was living and being buried in one locality
another and very diverse type could not have been doing the same things in
other distant localities.
This is how he expresses it:
"All competent authorities will probably assent to the proposition that
physical geology does not enable us in any way to reply to this question—Were
the British Cretaceous rocks deposited at the same time as those of
India, or were they a million of years younger, or a million of years older?"
This phase of the idea, however, is not so bad, for the human mind
refuses to believe that distant and disconnected groups of similar forms were
not connected in time and genetic relationship. It is really the reverse of
this proposition that contains the most essential absurdity, and this is the
very phase that is most essential to the whole succession of life idea.
Huxley, indeed, seems to have caught a glimpse of this truth, for he says:
"A Devonian fauna and flora in the British Islands may have been contemporaneous
with Silurian life in North America, and with a Carboniferous
fauna and flora in Africa. Geographical provinces and zones may have been
as distinctly marked in the Palaeozoic epoch as at present."
Certainly; but if this be true, it is equally certain that the Carboniferous
flora of Pennsylvania may have been contemporaneous alike with the Cretaceous
flora of British Columbia and the Tertiary flora of Germany and
Australia. But in that case what becomes of this succession of life which
for nearly a century has been the pole star of all the other biological sciences—I
might almost say of the historical and theological as well?
Must it not be admitted that in any system of clear thinking this whole
idea of there having really been a succession of life on the globe is not only
not proved by scientific methods, but that it is essentially unprovable and
absurd?
Huxley, in point of fact, admits this, though he goes right on with his
scheme of evolution, just as if he never thought of the logical consequences
involved. His words are:
"In the present condition of our knowledge and of our methods (sic)
one verdict—'not proven and not provable'—must be recorded against all
grand hypotheses of the palaeontologist respecting the general succession
of life on the globe."
In view of these startling facts, is it not amazing to see the supernatural
knowledge of the past continually and quietly assumed in every
geological vision of the earth's history?
Among the few stray principles that the future will probably be able to
save from the wreck of Spencer's philosophy, is the advisability of looking
into the genealogy of an idea. What has been its surroundings? What is
its family history? Does it come of good stock, or is its family low and not
very respectable?
This is especially true in the case of a scientific idea, which above all
others needs to have a clean bill of health and a good family record. But,
unfortunately, the idea we are here considering has a bad record, very bad
in fact; for the whole family of Cosmogonies, of which this notion is the only
surviving representative, were supposed to have been banished from the
land of science long ago, and were all reported dead. Some of them had
to be executed by popular ridicule, but most of them died natural deaths, the
result of inherited taint, in the latter part of the eighteenth and early nineteenth
centuries. It is perfectly astonishing how any of the family could
have survived over into the twentieth century, in the face of such an antecedent
record.
For one of the chief traits of the family as a whole is that of mental
disorder of various stages and degrees. Some of them were raving crazy;
others were mild and comparatively harmless, except that their drivel had
such a disturbing effect on scientific investigations that they had to be put
out of the way. It seems such a pity that when this last fellow, early in
life, was up before Doctors Huxley and Spencer for examination, he was not
locked up or put in limbo forthwith. This is especially unfortunate, because
this survivor of an otherwise extinct race has since then produced a large
family, some of which it is true have already expired, while the eldest son,
Darwinism, was reported in 1901 to be "at its last gasp,"[4] and was even
said last year to have had its "tombstone inscription" written by von Hartmann
of Germany. But the succession of life idea itself, the father of all
this brood, is still certified by those in authority to be healthy and compos
mentis.
The Cosmogony Family is a very ancient one, running back to the time
of Plato and Thales of Miletus. Indeed the cuneiform inscriptions of Babylonia
seem to indicate that a tribe with very similar characteristics existed
several millenniums before the Christian era. But discarding all these, the
first men that we need to mention are perhaps Burnet and Whiston, who
knew no other way of arriving at geological truth than to spin a yarn about
how the world was made. Woodward seems to have had a little better
sense, and is named along with Hooke and John Ray as one of the real
founders of the science.
Unfortunately the brood of Cosmogonists was not dead, for Moro and
De Maillet were at this same period spinning their fantastic theories about
the origin of things; or as Zittel puts it, "accepted the risks of error, and
set about explaining the past and present from the subjective standpoint."[5]
This tendency we will find to be a birthmark in the family, and will serve
to invariably identify any of them wherever found. We must remember
this, and apply the test to the modern survivors.
Buffon seems to have been really the founder of the family in the
modern form. He is credited with the sarcastic remark that "geologists
must feel like the ancient Roman augurs who could not meet each other
without laughing;" though in view of his fantastic scheme of seven "epochs,"
in which he endeavors to portray "the beginning, the past, and the future
(sic) of our planet,"[6] one is reminded of the common symptom which manifests
itself in thinking all the rest of the world crazy.
The "Heroic Age of Geology" succeeded this period, and was characterized
largely by a determination to discard speculation, and to seek to build
up a true science of actual fact and truth.
We have already seen from Spencer's remarks that A. G. Werner, who
was, however, one of the leaders in Germany at this time, was very far from
following true inductive methods. And the following language of Sir Arch.
Geikie shows that in him the family characteristics were decidedly prominent:
"But never in the history of science did a stranger hallucination arise
than that of Werner and his school, when they supposed themselves to discard
theory and build on a foundation of accurately-ascertained fact. Never
was a system devised in which theory was more rampant; theory, too, unsupported
by observation, and, as we now know, utterly erroneous. From beginning
to end of Werner's method and its applications, assumptions were
made for which there was no ground, and these assumptions were treated
as demonstrable facts. The very point to be proved was taken for granted,
and the geognosts, who boasted of their avoidance of speculation, were in
reality among the most hopelessly speculative of all the generations that
had tried to solve the problem of the theory of the earth."[7]
In fact this author says that:
"The Wernerians were as certain of the origin and sequence of the
rocks as if they had been present at the formation of the earth's crust."
(pp. 288-9.)
Here we see the family characteristics very strongly developed.
In speaking of Werner's five successive "suites" or onion-coats in which
he wrapped his embryo world, Zittel complains:
"Unfortunately, Werner's field observations were limited to a small
district, the Erz mountains and the neighboring parts of Saxony and Bohemia.
And his chronological scheme of formations was founded upon the
mode of occurrence of the rocks within these narrow confines." (p. 59.)
And yet, as we have seen, it is precisely such a charge as this that
Spencer and Huxley bring against the modern phase of the doctrine of
successive ages based on the succession of life idea. Werner, from observations
"limited to a small district," constructed his scheme of exact chronological
sequence, basing it entirely upon the mineral or mechanical character
of his "suites." And hundreds of enthusiastic followers long declared that
the rocks everywhere conformed to this classification, even so great an
observer as von Humboldt thinking that the rocks which he examined in
Central and South America fully confirmed Werner's chronological arrangement.
But such notions to-day only cause a smile of pity, for it is now well
known that, take the world over, the rocks do not occur as Werner imagined,
though, as Geikie says, he and his disciples were as certain of the matter
"as if they had been present at the formation of the earth's crust." Besides,
as already pointed out, we moderns ought now to have pretty well assimilated
the idea that while one kind of mineral or rock was forming in one
locality, a totally different kind of deposit may have been in process of
formation in another spot some distance off at the very same time, and we
cannot imagine a time in the past when this principle would not hold good.
But in a precisely similar way the idea of a time value was, as we shall see,
transferred from the mechanical and mineral character of the rocks to their
fossil contents; and from observations again "limited to a small district,"
William Smith and Cuvier conceived the idea that the fossils occurred only
in a certain order; that only certain fossils lived at a certain time; that,
for example, while Trilobites were living and dying in one locality, Nummulites
or Mammals positively were not living and dying in another locality,
though in any system of clear thinking this latter notion is just as irrational
as that of Werner. Hence Spencer is compelled to say, "though the onion-coat
hypothesis is dead, its spirit is still traceable, under a transcendental
form, even in the conclusions of its antagonists."
The two cases are exactly parallel; only it has taken us nearly a
hundred years, it seems, to find out that the fossils do not follow the prearranged
order of Smith and Cuvier any better than the rocks and minerals
do the scheme of Werner. If hundreds of geologists still seem to think that
the fossils in general agree with the standard order, we must remember
how many sharp observers said the same thing for decades about Werner's
scheme. The taint of heredity will always come out sooner or later; and
both of these schemes exhibit very strongly the family history of the whole
tribe of Cosmogonies, viz., the facts refuse to certify that they are of sound
mind.
It was William Smith, an English land surveyor, who first conceived the
idea of fixing the relative ages of strata by their fossils. Just how far he
carried this idea it seems difficult to determine exactly. Lyell[8] says nothing
along this line about him, save that he followed the leading divisions of the
Secondary strata as outlined by Werner, though he claims "independently"
of the latter. Whewell[9] remarks rather pityingly on his having had "no
literary cultivation" in his youth, but has nothing about the degree in which
he is responsible for the modern scheme of life succession of which many
modern geologists have made him the "father". Geikie and Zittel are
much more explicit. The former[10] says that "he had reached early in life
the conclusions on which his fame rests, and he never advanced beyond
them." "His plain, solid, matter-of-fact intellect never branched into theory
or speculation, but occupied itself wholly in the observation of facts."
Zittel[11] says pretty much the same thing, remarking that "Smith confined
himself to the empirical investigation of his country, and was never tempted
into general speculations about the history of the formation of the earth"—words
which to my mind are the very highest praise, for they seem to indicate
that he was only in a very limited way responsible for the unscientific
and illogical scheme of a "phylogenic series" or complete "life-history
of the earth," which now passes as the science of geology. Doubtless
like his little bright-eyed German contemporary, A. G. Werner, he had not
had his imagination sufficiently cultivated in his youth to be able to appreciate
the beauty of first assuming your premises and then proving them
by means of your conclusion, i.e., first assuming that there has been a
gradual development on the earth from the lowest to the highest, and then
arranging the fossils from scattered localities over the earth in such a way
that they cannot fail to testify to the fact.
The following may be taken as a fair statement of what he actually
accomplished and taught:
"After his long period of field observations, William Smith came to
the conclusion that one and the same succession of strata stretched through
England from the south coast to the east, and that each individual horizon
could be recognized by its particular fossils, that certain forms reappear
in the same beds in the different localities, and that each fossil species
belongs to a definite horizon of rock."[12]
But even granting the perfect accuracy of this generalization of Smith's
for the rocks which he examined, I fail to see how it is any better than
Werner's scheme, which Zittel characterizes as "weak" and premature, and
of which Whewell (p. 521) says that "he promulgated, as respecting the
world, a scheme collected from a province, and even too hastily gathered
from that narrow field."
Quoting again from Zittel's criticism of Werner's work ("Hist. of Geology,"
p. 59), we must admit that Smith's observations also were "limited
to a small district," and "his chronological scheme of formations was
founded upon the mode of occurrence of the rocks (fossils) within these
narrow confines." There is, as we have shown, a monstrous jump from this
to the conclusion that even these particular fossils must always occur in
this particular relative order over the whole earth. How can any one deny
that if we had a complete collection of all the fossils laid down during the
last thousand years—when all admit that the so-called "phylogenic series"
is complete—particular fossils would in many cases be found to occur only
in particular rocks, and we could still arrange them in this same order from
the lowest to the highest forms of life, while we might even happen to
find "small districts" where the "mode of occurrence of the rocks within
these narrow confines" would have all the appearance of showing a true
"phylogenic" order. This of itself ought to be sufficient to show us the
weakness of this subjective method of study, and the purely hypothetical
and imaginary value of the fossils in determining the real age of a rock
deposit.
The name of Baron Cuvier is the next that we have to consider. An
examination of part of his teaching will come naturally a little later when
considering "extinct species." That part of his work which related to the
doctrine of Catastrophism is somewhat aside from the subject of our study;
while with regard to his influence on the succession of life idea per se
there is not very much that need be said. And yet Cuvier is the real
founder of modern cosmological geology, and thus in a certain sense the
father of biological evolution.
But if the absence of the architectonic mania for building a cosmogony
will serve to remove in a great measure any suspicions with regard to
William Smith's results, we cannot say the same for those of Cuvier. In
his scheme the hereditary Cosmological taint, which is such an invariable
characteristic of the family, is very strong, though disguised and almost
transfigured by learning and genius. It is doubtless these latter qualities
which have secured for the theory such a phenomenal length of life, though
of course we know that nothing born of this whole brood can ever secure
a permanent home in the kingdom of science.
"How glorious," wrote this otherwise truly great man in his famous
"Preliminary Discourse," "it would be if we could arrange the organized
products of the universe in their chronological order, as we can already
(Werner's onion-coats) do with the more important mineral substances!"
His work (with that of his co-laborer Brongniart) on the fossils of the
Paris basin was probably accurate and logical enough for that limited
locality. It was only when he quietly assumed as Werner had done, that
the rocks must always occur in this particular order all over the world, or
as Whewell expresses it, "promulgated as respecting the world, a scheme
collected from a province, and (perhaps) even too hastily gathered from that
narrow field"—it was only, I say, when this monstrous assumption was
incorporated into his scheme, and he began to call into being his vision
of organic creation on the instalment plan, as Werner had done with the
minerals, that his great and valuable work for science became tainted with
the deadly Cosmological virus, dooming it to death sooner or later. Sherlock
Holmes might attempt to diagnose a disease by a mere glance at his patient's
boots, but even this gave him more data and was a more logical
proceeding than the facts and methods of Cuvier supplied for constructing
a scheme of organic creation.
It will not be necessary to detail the manner in which the modern
"phylogenic series" was gradually pieced together from the scattered fragments
here and there all over the globe; but it should be noted here that
the whole chain of life was practically complete before any serious attempt
was made to study the rocks on the top of the ground, and to find out how
this marvellous record of the past joined on to the modern period, thus
reversing completely the true inductive method, and leaving the most important
of all, viz., the rocks containing human remains and other living
species, over till the last, with the result that we have for over half a
century been laboring under a "Glacial Nightmare," and these deposits on
the top of the ground "still remain in many respects the despair of
geology."
Then came Lyell, Agassiz, and Darwin; and now in the light of the
keen discussions instituted by Weismann in the later eighties of the last
century, the modern world is pretty well agreed on two results, viz., that
so far from natural selection being able to originate a species, it can't
possibly originate anything at all, and also that no individual can transmit
to his descendants what he has himself acquired in his lifetime, and hence it
is hard to see how he can transmit what he has not got himself and what
none of his ancestors ever had.
I have not the space to show how Agassiz further complicated the
problem immensely by his absurdly illogical use of his three "laws" of
comparison, when the prime fact of there ever having been a succession of
life on the globe in any order whatever had never been proved; but I am
free to say that if Cuvier's system of creation on the instalment plan had
been fact instead of fancy, some scheme of evolution would undoubtedly
be implied in this general fact. It is this instinctive feeling on the part of
modern scientists which makes them to-day, while confessing the failure of
Darwinism, still cling to the general idea of evolution somehow. Hence it
seems quite evident that, having deviated from strict inductive methods by
pursuing this ignis fatuus of a cosmological history of creation, it was
essential in the interests of true science to go the whole journey and make
a complete investigation of the biological side of the question, in order to
complete the demonstration that science was on a wrong tack entirely.
Darwin and Weismann were inevitable in view of the wholly unscientific
course on which biology entered under the guidance of Buffon and Cuvier.
What then can we take as the general lesson to be learned from the
stubborn way in which, for over a hundred years, the world has followed
this hypnotic suggestion of folly, that we might explain our genesis and
being from the scientific standpoint? One of the lessons—there may be
others—is that science knows nothing about origins, and that, in speculating
along these lines, the cosmological taint will always vitiate the accuracy of
our conclusions and debauch the true spirit of induction. A hundred years
ago, they thought they knew all about how the world was made. The
keen investigations inspired by Darwinism were necessary to convince us
that we know nothing at all about it. Modern biology has simply developed
a gigantic reductio ad absurdum argument against the easy assumptions of
the earlier geologists that it occurred by a progression from the low to the
high. A hundred years—nay fifty years ago—this assumption did not
appear so unscientific, for we did not then have the biological evidence to
refute such an idea. Now, however, in the light of the modern progress of
science, this awful mystery of our existence, of our creation and destiny,
is borne in upon us from every dividing cell, from every sprouting seed,
from countless millions of the eloquent voices of nature, which our forefathers
were too blind to see, too deaf to understand; and with weary,
reluctant sadness does science confess that about it all she knows absolutely
nothing.
Hitherto we have been dealing only with the a priori aspects of the
succession of life idea. We have seen that it is really based on two primary
assumptions, viz.:
(1) That over all the earth the fossils must always occur in the particular
order in which they were found to occur in a few corners of Western
Europe; and also—
(2) That in the long ago there were no such things as zoological provinces
and zones, and totally different types of fossils from separated localities
could not possibly have been contemporaneous with one another as
we know they are to-day in "recent" deposits.[13]
On the blending of these two assumptions, the latter essentially absurd,
and the former long ago disproved by the facts of the rocks, has been built
up the towering structure of a complete "phylogenic series" from the Cambrian
to the Pleistocene. The way in which, as we have been, Spencer
and Huxley treated this subject, reminds us very much of the old advice,
"When you meet with an insuperable difficulty, look it steadfastly in the
face—and pass on." For neither they nor any of their thousands of followers
have ever, so far as I know, pointed out the horrible logic in taking this
immense complex of guesses and assumptions as the starting-point for new
departures, the solid foundation for detailed "investigations" as to just how
this wonderful phenomenon of development has occurred. For after Agassiz
and his contemporaries had built on these large assumptions of Cuvier,
and had arranged the details and the exact order of these successive forms
by comparison with the embryonic life of the modern individual, the
evolutionists of our time, led by such men as Spencer and Haeckel, with
their "philogenetic principle," prove their theory of evolution by showing
that the embryonic life of the individual is only "a brief recapitulation, as
it were from memory," of the geological succession in time. There would
really seem to be little hope of reaching with any arguments a generation
of scientists who can elaborate genealogical trees of descent for the different
families and genera of the animal kingdom, based wholly on such a series
of assumptions and blind guesses, and then palm off their work on a
credulous world as the proved results of inductive science.
And yet I am tempted to make some effort in this direction. And since
we have now examined the a priori aspects of the question, it remains to
test the two above mentioned assumptions by the facts of the rocks. The
second, indeed, involving as it does a profound supernatural knowledge of
the past, and being so positively contrary to all that we know of the modern
world as to seem essentially absurd, is yet by its very nature beyond the
reach of any tests that we can bring to bear upon it. Hence it remains to
test by the facts of the rocks the assumption that all over the earth the
fossils invariably occur in the particular order in which they were first
found in a few corners of Western Europe by the founders of the science.
Have we already a sufficiently broad knowledge of the rocks of the world
to decide such a question? I think we have.
To begin then at the beginning, let us try to find out how we can fix
on the rocks which are absolutely the oldest on the globe. We would
expect to find a good many patches of them here and there, but there must
be some common characteristic by which they may be distinguished wherever
found. Of course, when I say "rocks" here I mean fossils, for as has
long been agreed upon by geologists, mineral and mechanical characters
are of practically no use in determining the age of deposits, and we are here
dealing only with life and the order in which it has occurred on the globe.
Accordingly our problem is really to find that typical group of fossils which
is essentially older than all dissimilar groups of fossils.
In most localities we do not have to go very far down[14] into the earth
to find granite or other so-called igneous rocks, which not only do not contain
any traces of fossils, but which we have no proper reason for supposing
ever contained any. These Azoic or Archaean rocks constitute practically
all the earth's crust, there being only a thin skim of fossiliferous
strata on the outside somewhat like the skin on an apple. Now it would
be natural enough to suppose that those fossils which occur at the bottom,
or next to the Archaean, are the oldest. This is doubtless what the earlier
geologists had in mind, or at least ought to have had, for it is not quite
certain that they had any clear thoughts on the matter whatever. They
did not really begin at the bottom, but half way up, so to speak, at the Mesozoic
and Tertiary rocks, and Sedgwick and Murchison, who undertook to find
bottom, got too excited over their Cambro-Silurian controversy to attend to
such an insignificant detail as the logical proof that any type of fossils was
really older than all others. If they had really stopped to consider that
some type of fossil might occur next to the Archaean in Wales, and another
type occur thus in Scotland, while still another type altogether might be
found in this position in some other locality, and so on over the world,
leading us to the very natural conclusion that in the olden times as now
there were zoological provinces and districts, the history of science during
the nineteenth century might have been very different, and this chapter
might never have been written. But this commonplace of modern geology,
that any type of fossil whatever, even the very "youngest," may occur next
to the Archaean, was not then considered or understood; and when about
1830 it came to be recognized, other things were allowed to obscure its
significance, and the habit of arranging the rocks in chronological order
according to their fossils was too firmly established to be disturbed by such
an idea.
But the Fact Number One, which I have chosen as the subject of this
chapter, is the now well established principle that any kind of fossil whatever,
even "young" Tertiary rocks, may rest upon the Archaean or Azoic
series, or may themselves be almost wholly metamorphosed or crystalline,
thus resembling in position and outward appearance the so-called "oldest"
rocks.
The first part of this proposition, about any rocks occurring next to the
Archaean, is covered by the following quotation from Dana:[15]
"A stratum of one era may rest upon any stratum in the whole of the
series below it,—the Coal-measures on either the Archaean, Silurian, or
Devonian strata; and the Jurassic, Cretaceous, or Tertiary on any one of
the earlier rocks, the intermediate being wanting. The Quaternary in
America in some cases rests on Archaean rocks, in others on Silurian or
Devonian, in others on Cretaceous or Tertiary."
It would be tedious to multiply testimony on a point so universally
understood.
As for the other half of this fact, that even the so-called "youngest"
rocks may be metamorphic and crystalline just as well as the "oldest," it
also is now a recognized commonplace of science. Dana[16] says that as early
as 1833 Lyell taught this as a general truth applicable to "all the formations
from the earliest to the latest."
The first reference I can find to any disproof of this old fable of Werner's,
that only certain kinds of rock are to be found next to the "Primitive"
or Archaean, is in the observations of Studer and Beaumont in the Alps,
(1826-28), who found "relatively young" fossils in crystalline schists, which, as
Zittel says, "was a very great blow to the geologists who upheld the hypothesis
of the Archaean or pre-Cambrian age of all gneisses and schists."
James Geikie, doubtless referring to the same series of rocks, tells us
that:—
"In the central Alps of Switzerland, some of the Eocene strata are so
highly metamorphosed that they closely resemble some of the most ancient
deposits of the globe, consisting, as they do, of crystalline rocks, marble,
quartz-rock, mica schist, and gneiss."[17]
Hence we need not be surprised at the following statement of the situation
by Zittel.[18]
"The last fifteen years of the nineteenth century witnessed very great
advances in our knowledge of rock-deformation and metamorphism. It has
been found that there is no geological epoch whose sedimentary deposits
have been wholly safeguarded from metamorphic changes, and, as this
broad fact has come to be realized, it has proved most unsettling, and has
necessitated a revision of the stratigraphy of many districts in the light of
new possibilities. The newer researches scarcely recognize any theory;
they are directed rather to the empirical method of obtaining all possible
information regarding microscopic and field evidences of the passage from
metamorphic to igneous rocks, and from metamorphic to sedimentary rocks."
But in addition to what Zittel means by recognizing "no theory" as to
the origin of the various sorts of "igneous" rocks, it seems to me that this
"broad fact" ought surely to prove "most unsettling," to the traditional
theories about certain fossils being intrinsically older than others. With
our minds divested of all prejudice, and this "broad" Fact Number One
well comprehended, that any kind of fossil whatever may occur next to
the Archaean, and the rocky strata containing it may in texture and appearance
"closely resemble some of the most ancient deposits on the globe,"
where on this broad earth shall we look for the place to start our life-succession
That is, where can we now go to find those kinds of fossils which
we can prove, by independent arguments, to be absolutely older than all
others? It may seem very difficult for some of us to discard a theory so
long an integral part of all geology; but until it can be proved that this
"broad fact" as stated by Zittel and Dana is no fact at all, I see no escape
from the acknowledgment that the doctrine of any particular fossils being
essentially older than others is a pure invention, with absolutely nothing in
nature to support it.
Or, to state the matter in another way, since the life succession theory
rests logically and historically on Werner's notion that only certain kinds
of rocks (fossils) are to be found at the "bottom" or next to the Archaean,
and it is now acknowledged everywhere that any kind of rocks whatever
may be thus situated, it is as clear as sunlight that the life succession theory
rests logically and historically on a myth, and that there is no way of proving
what kind of fossil was buried first.
Of course, the reason the followers of Cuvier and his life succession now
find themselves in such a fix as this is because they have not been following
true inductive methods. Theirs has been a geology by hypothesis instead
of by observed fact. They started out with a pretty scheme ready-made
about the origin and formation of the world, perfectly innocent of any evil
intent in such a method of procedure, and unconscious of its speculative
character; and for nearly a hundred years they have supposed that they
were following inductive methods in Geology. But in view of what we have
now learned I think we are perfectly justified in adapting and applying to
Cuvier and the modern school of geologists what Geikie[19] says about Werner
and his school:
"But never in the history of science did a stranger hallucination arise
than that of Cuvier and the modern school, when they supposed themselves
to discard theory and build on a foundation of accurately ascertained fact.
Never was a system devised in which theory was more rampant; theory,
too, unsupported by observation, and, as we now know, utterly erroneous.
From beginning to end of Cuvier's method and its applications, assumptions
were made for which there was no ground, and these assumptions were
treated as demonstrable facts. The very point to be proved was taken for
granted, and the evolutionary geologists who boasted of their avoidance of
speculation, were in reality among the most hopelessly speculative of all
the generations that had tried to solve the problem of the theory of the
earth."
If we had ample evidence that a certain man was personally acquainted
with Julius Caesar, that they were born in the same town, went to school
together, served in the same wars, and later carried on an extensive mutual
correspondence, would we not conclude that they must have lived in the
same age of the world's history? I confess that the conclusion seems quite
unavoidable. Who would dream that eighteen centuries or more had separated
the two lives, and that while one was an old Roman the other was
an American of the latter nineteenth century?
Some such a puzzle as this is presented in geology under the general
subject of conformability. Let me define this term.
Strata laid down by water are in the first place in a horizontal position.
Some subsequent force may have disturbed them, so that we may now find
them standing up on edge like books in a library. But all human experience
goes to show that they were not deposited in this position. Some
disturbing cause must have taken hold of them since they were laid down,
for the water in which they were made must have spread them out smooth
and horizontal, each subsequent layer or stratum fitting "like a glove" on
the preceding. Thus when we find two successive layers agreeing with
one another in their planes of bedding, with every indication that the lower
one was not disturbed in any way before the upper one was spread out
upon it, the two are said to be conformable. But if the lower bed has
evidently been upturned or disturbed before the other was laid down, or if
its surface has even been partly eroded or washed away by the water, the
strata are said to be unconformable, or they show unconformability in bedding.
Of course, in all this we are dealing only with relative time. When
we find one bed or stratum lying above another in their natural position,
the lower one is of course the older of the two; but whether laid down ten
minutes earlier, or ten million years earlier, how are we to determine?
Ignoring the matter of the fossils they contain, must we not own that,
though there is no way of telling just how much longer the lower one
was deposited before the next succeeding, yet if the two are conformable
to one another, and the bottom one shows no evidence of disturbance or
erosion before the other was fitted upon it, the strong presumption would
seem to be that no great length of time could have elapsed between the laying
down of the two layers. To say that we have here a geological example
similar to that of a modern American having been personally acquainted
with Julius Caesar, would seem to be quite "inexplicable," as Herbert
Spencer used to say.
But if the life succession theory be true, we have just such a conundrum
in our Fact Number Two, which is that any formation whatever may rest
conformably upon any other "older" formation.
The lower may be Devonian, Silurian, or Cambrian, and the upper one
Cretaceous or Tertiary, and thus according to the theory millions on millions
of years must have elapsed after the first, and before the following
bed was laid down, but the conformability is perfect, and the beds have all
the appearance of having followed in quick succession. Sometimes, too,
though less frequently, these age-separated formations are lithologically the
same, and can only be separated by their fossils!
But before going into the minute description of any of these cases, we
must notice some general statements. Thus as long ago as the date of
the publication of "The Origin of Species," Darwin, in speaking of the "Imperfection
of the Geological Record," could speak of "The many cases on
record of a formation conformably covered, after an immense interval of
time, by another and later formation, without the underlying bed having
suffered in the interval by any wear and tear."[20]
Also Geikie,[21] in speaking of how "fossil evidence may be made to prove
the existence of gaps which are not otherwise apparent," says that "It is
not so easy to give a satisfactory account of those which occur where the
strata are strictly conformable, and where no evidence can be observed of
any considerable change of physical conditions at the time of deposit. A
group of quite conformable strata having the same general lithological
characters throughout, may be marked by a great discrepance between the
fossils of the upper and the lower part." In many cases he says these conditions
are "not merely local, but persistent over wide areas.... They
occur abundantly among the European Palaeozoic and Secondary rocks,"
and are "traceable over wide regions."
We have seen how Dana admits that "A stratum of one era may rest
upon any stratum in the whole series below it, ... the intermediate
being wanting." He classes this under the head of the "Difficulties" of the
science, quite naturally as it would seem, though he does not expressly
assert that these age-separated formations are often conformable to one
another, as Geikie and Darwin have said in the above given quotations.
The literature really teems with illustrations of these facts, and the more
detailed accounts contained in the various Geological Reports are often
quite charmingly naive in their description of the conditions. Two examples,
however, must suffice, both from the Canadian North West.
The first is from the Report on the region about Banff, in Alberta, near
the line of the Canadian Pacific Railway, and just east of the Rockies.
"East of the main divide the Lower Carboniferous is overlaid in places
by beds of Lower Cretaceous age, and here again, although the two formations
differ so widely in respect to age, one overlies the other without any
perceptible break, and the separation of one from the other is rendered more
difficult by the fact that the upper beds of the Carboniferous are lithologically
almost precisely like those of the Cretaceous (above them.) Were it
not for fossil evidence, one would naturally suppose that a single formation
was being dealt with."[22]
The other example is from the District of Athabasca.
"The Devonian limestone is apparently succeeded conformably by the
Cretaceous, and with the possible exception of a thin bed of conglomerate
of limited extent, which occurs below Crooked Rapid on the Athabasca, the
age of which is doubtful, the vast interval of time which separated the two
formations, is, so far as observed, unrepresented either by deposition or
erosion."[23]
Of course, some geological writers labor to explain this thundering
rebuke of their theory, just as the Ptolemaic astronomers had their "deterrents"
and "epicycles" for every new difficulty. But surely the detailed records
of such observations as these are fearful examples of the power of
tradition to blind the minds of investigators to the meaning of the very
plainest facts.
On a previous page (Id. p. 51,) the author last quoted gives us some idea
of the "remarkable persistence" of this instructive case of conformability,
which extends from the Athabasca "in a broad band around the southern
end of Birch Mountains, and across Lake Claire to Peace River, and up the
latter stream to a point two miles above Vermillion Falls."
The distance, as I judge from the map, can not be less than 150 miles
in a straight direction, thus making a district of probably several thousand
square miles in extent where, according to the theory of a life succession,
nature must have put an injunction on the action of the elements, and they
had to continue in the status quo for millions of ages, or from the Devonian
to the Cretaceous "age," the water neither wearing away nor building up
over any part of this consecrated ground during all this time.
Nor is this all, for from Part E, Report (p. 209) of this same volume, we
are told of strata near Lake Manitoba, over 500 miles away, in almost the
same wonderful relationship,—"Devonian rocks very similar in character"
to those in Athabasca still overlaid directly by the Cretaceous, though in
this case as it happens "unconformably." It would almost seem to be a
bona fide case of Werner's onion coats cropping out.
And all this incredible picture of nature's inconsistent behaviour in
past ages is necessitated solely by the loving allegiance with which the
infallibility of the life succession theory is regarded by modern geologists.
How many of us have ever seen a mountain fall? Not very many.
And yet events even more wonderful than this have frequently occurred in
the past, as we are confidently assured by the leaders in geological science.
Thus, in speaking of a certain region in the Alps, Dana[24] says that "one
of the overthrust folds has put the beds upside down over an area of 450
square miles."
It is well worth our while to try to understand this statement. Our
first and most natural inquiry is, What is it that leads scientists to think so?
The details of this particular case are not very accessible, and so we are
driven to reasoning from analogy from the known methods and constructions
employed in this science. We must agree that none of the authorities
who report this circumstance can testify as eye-witnesses of this marvellous
event: they were not there on the spot when old Mother Earth turned this
huge calcareous and silicious pancake. And yet there must be some kind
of evidence by which these eminent men have arrived at this conclusion.
What kind of evidence can it be?
We cannot imagine any physical evidence which could even remotely
suggest such an idea. In fact from the universal custom of making the
contained fossils the supreme test of the age of a rock deposit, we are
perfectly safe in concluding that it is solely because the fossils occur here
in the reverse of the accepted order, that we have this astounding picture
of an immense mountain mass having been put "upside down over an area
of 450 square miles." The "older" fossils are evidently here on top, while
the "younger" ones are underneath, and of course some explanation must
be given of this flat contradiction of the life succession theory.
But let us retrace our steps somewhat, and pick up the thread of our
argument. We have already found quite serious reason to question the
accuracy of this life succession theory: but there is still another way of
testing its rationality. If certain fossils are not necessarily older than certain
others, it might reasonably be expected that we would now and then
find them reversed as to position, i.e., with the "younger" below and the
"older" above. Accordingly we have the following very necessary caution
from Prof. Nicholson:[25]
"It may even be said that in any case where there should appear to be
a clear and decisive discordance between the physical and the palaeontological
(fossil) evidence as to the age of a given series of beds, it is the former
that is to be distrusted rather than the latter."
To meet all ordinary cases of this character, where the differences
involve only a few formations representing a few "ages" or a few million
years, the theory of pioneer "colonies" was invented by Barrande in 1852.
But for extreme cases, say where Silurian or Cambrian fossils occur above
Jurassic, Cretaceous or Tertiary, there is in such a predicament always an
anxious search made for faults and displacements; or gigantic "thrust-faults"
or "overthrust folds," like the example already quoted from Dana,
are described in picturesque language, many miles in extent—inventions
which, as I have already suggested of a similar expedient to explain away
evidence, deserve to rank with the famous "epicycles" of Ptolemy, and will
do so some day.
Here is Geikie's highly instructive statement regarding the same conditions:—
"We may even demonstrate that in some mountainous ground, the
strata have been turned completely upside down, if we can show that the
fossils in what are now the uppermost layers ought properly to lie underneath
those in the beds below them."[26]
Some day, I fancy, a statement like this will be regarded as a literary
curiosity.
There are plenty of examples under this head, though two or three
ought to be as good as a dozen. In the part of Alberta east of the Rockies
already referred to, is a section of country of about fourteen square miles
at least—and we know not how much more—where Cambrian fossils are
found above Cretaceous, and the inevitable "thrust fault" is thus described
by one of the officers of the Canadian Geological Survey. He has just been
speaking of "a series" of these "gigantic thrust faults":—
"One of the largest and most important of these occurs along the eastern
base of the chain, and brings the Cambrian limestones of the Castle Mountain
group over the Cretaceous of the foot hills. This fault has a vertical
displacement of more than 15,000 feet (? three miles), and an estimated
horizontal displacement of the Cambrian beds of about seven miles in an
easterly section. The actually observed overlap amounts to nearly two
miles. The angle of inclination of its plane to the horizon is very low, and
in consequence of this its outcrop follows a very sinuous line along the
base of the mountains, and acts exactly like the line of contact of two
nearly horizontal formations.
"The best places for examining this fault are at the gaps of the Bow
and of the south fork of the Ghost River. At the former place the Cretaceous
shales form the floor of the bay which the Bow has cut in the eastern
wall of the range, and rise to a considerable height in the surrounding
slopes. Their line of contact with the massive gray limestones of the overlying
Castle Mountain group is well seen near the entrance of the gap in
the hills to the north. The fault plane here is nearly horizontal, and the
two formations, viewed from the valley, appear to succeed one another
conformably."[27]
But what an amazing condition of affairs is this. Here are great mountainous
masses of rock, very similar in mechanical and mineral make-up
to thousands of examples elsewhere. The line of bedding between them
"acts exactly like the line of contact of two nearly horizontal formations,"
and in a natural section cut out by a river the two "appear to succeed one
another conformably." And yet we are asked to believe that all this is
merely an optical illusion. The rocks could not possibly have been deposited
in this way, for the lower ones contain "Benton fossils" (Cretaceous),
and the upper ones are Cambrian, and almost the whole geological series
and untold millions of years occurred after the upper one, and before the
lower one was formed. Solely on the strength of the infallibility of a theory
invented a hundred years ago in a little corner of Western Europe, which
"promulgated, as respecting the world, a scheme collected from that province,"
and assumed that over all the world the rocks must always follow the
order there observed, we are here asked to deny the positive evidence of our
senses because these rocks do not follow this accepted order. I must confess
that I cannot see the force of such a method of reasoning. It is carrying
the argument several degrees beyond the reasoning of the three little
green peas in the little green pod, as narrated in the exquisite fable of
Eugene Field. These wise little fellows noticed that their little world was
all green, and they themselves green likewise, and they shrewdly concluded
from this that the whole universe must also be green. But we are not told
of their travelling abroad and persisting in a systematic attempt to explain
all subsequently observed facts in terms of their theory.
This government Report last quoted from says that in the eastern part
of Tennessee the Appalachian Chain "presents an almost identical structure,"
and refers to a similar state of things in the Highlands of Scotland. Dana,
in the last edition of his "Manual" (p. 369), refers to this report, and reproduces
some of its plates showing some of the structures referred to; and
on another page, in speaking of this similar example in Scotland, says that
"a mass of the oldest crystalline rocks, many miles in length from north to
south, was thrust at least ten miles westward over younger rocks, part of
the latter fossiliferous"; and further declares that "the thrust planes look
like planes of bedding, and were long so considered."[28]
Geikie quite naturally devotes several pages in his "Text-Book" to a
description of these conditions in the Highlands; but from one of his first
reports on these observations, published in Nature[29] we get some much more
suggestive details. The thrust-planes, he says, are difficult to be "distinguished
from ordinary stratification planes, like which they have been
plicated, faulted, and denuded. Here and there, as a result of denudation,
a portion of one of them appears capping a hill-top. One almost refuses
to believe that the little outlier on the summit does not lie normally
on the rocks below it, but on a nearly horizontal fault by which it has been
moved into its place."
Speaking of some similar conditions in Ross Shire, which he himself
had previously described as naturally conformable, he declares:—
"Had these sections been planned for the purpose of deception they
could not have been more skillfully devised ... and no one coming
first to this ground would suspect that what appears to be a normal stratigraphical
sequence is not really so."
"When a geologist finds" things in this condition, he says, "he may
be excused if he begins to wonder whether he himself is not really standing
on his head."
But I would only weary the reader by attempting to pursue this subject
further. Those who wish to do so will find many additional examples in
the larger works of Dana, LeConte, Prestwich, and Geikie, to say nothing
of the more detailed statements buried in numerous Government Reports
and special monographs in German and French.
From the very same set of beds different observers try to explain these
puzzles in very different ways. Some, like Helm, will describe gigantic
overthrust folds, and will draw immense arcs of circles several miles high
in the air, as the place where the rocks must once have been. Others,
like Rothpletz, from an examination of the very same rocks, will cut the
mountain up into sections with imaginary fault-planes, and will tell how, in
the district about Glarus for example, an enormous mass of mountains
"travelled from east to west a distance of about twenty-five miles from the
Rhine valley to the Linth," or how the "Rhatikon Mountain mass travelled
from Montafon valley to the Rhine valley, about nineteen miles from east
to west."[30]
With regard to some at least of these conditions in the Alps, Geikie
virtually admits that these incredible and self-contradictory earth-movements
are necessitated by and described from fossil evidence only, for he
says:—
"... the strata could scarcely be supposed to have been really
inverted, save for the evidence (sic) as to their true order of succession
supplied by their included fossils." "... portions of Carboniferous
strata appear as if regularly interbedded among Jurassic rocks, and indeed
could not be separated save after a study of their enclosed organic remains."[31]
In fact, we are perfectly safe in concluding in all similar cases that we
may encounter in the literature of the science that it is the reversed order
of the fossils which constitutes the whole evidence; for, as I have said,
we can imagine no possible physical evidence competent to form a foundation
for such ideas, nor do I know of anything save the exigencies of this venerable
theory of life succession, for which otherwise competent observers will
thus freely sacrifice their common sense. When the dividing line between
two sets of strata "acts exactly like the line of contact between two nearly
horizontal formations," so much so that in a natural section cut out by a
river the two "appear to succeed one another conformably," a calm judicial
mind, divested of all theoretical prejudice, instead of talking about these
conditions having been planned by nature "for the purpose of deception,"
will find no difficulty at all in believing that these rocks were really laid
down in the reverse order in which we now find them, with the "younger"
below and the "older" above, and only one under the hypnotic spell of a
preconceived theory would at the suggestion of such a fact begin "to wonder
whether he himself is not really standing on his head."
There is only one class of agents now working upon the rocks of the
globe which have been in business continuously ever since the dry land appeared,
and which have left us a legible record of approximately the amount
of business they have been doing all these centuries. And my Fact Number
Four, which will complete this line of argument in illustrating the antagonism
between the facts of the rocks and the theory of life succession, is
that the rivers of the world, which of course are the agents to which I have
referred, in traveling across the country, act precisely as if they knew nothing
of the varying ages of the rocks, but on the contrary treat them all alike
as if they were of the same age, and as if they began sawing at them all at
the same time. Of course it is, evidently, in only a few cases where the
records are so free from ambiguity as to be quite incapable of being misunderstood,
that is, the cases of rivers with steep rocky gorges, or those that
cut through mountain ranges; but there are several such rivers in the world,
and they all seem to tell the same story.
The famous Colorado River is a good example. It flows from "younger"
strata into "older" in its deep cutting across the Arizona plateau.[32] Stated
in terms of the current theory, this means that when the region of country
about the lower part of this river's course first became dry land, the upper
part was still sea, and that thus there was no such river in existence here
until the very "youngest" of these rocks was formed. For otherwise the
river must have started running from the sea toward the dry land, i.e.,
running up hill. Stated in terms neutral as to theory, it means that the
whole of this region of country, drained by this large river, with its rocks
of many varying "ages," was all elevated practically as it is now before this
river began its work of erosion. It treats all these rocks as if they were of
the same age, and as if it began sawing at them all at the same time.
Also its companion, the Green River, cuts through the Uinta Range in
the same manner. Similar conditions are said to occur on the Danube, and
in the river-courses of the Himalayas, and elsewhere.
In the case of the Colorado, Zittel says that:
"Powell's explanation of the apparent enigma is that after the river had
eroded its channel rocks were uplifted in one portion of its course, but so
slow was the rate of uplift that the river was enabled to deepen its channel,
either proportionately or more rapidly, so that it was never diverted from its
former course."
It was by similarly cunning inventions that the early writers on astronomy,
alchemy, and medicine evaded the force of accumulated facts
which told against their absurd theories.
We have now completed our survey of the strictly stratigraphical phases
of this question, and have found four very remarkable principles about the
rocks, which I wish to summarize here before proceeding further.
(1) The "broad fact," as stated by Zittel and Dana, that any kind of
rocks whatever, i.e. containing any kinds of fossils, even the "youngest,"
may rest on the Archaean, and may thus in position, as also in texture and
appearance, resemble the very oldest deposits on the globe.
(2) That any kind of beds may rest in such perfect conformability on
any other so-called "older" beds over vast stretches of country that, "were
it not for fossil evidence, one would naturally suppose that a single formation
was being dealt with," while "the vast interval of time intervening is
unrepresented either by deposition or erosion." The youngest seem to have
followed the oldest in quick succession.
(3) That in very many cases and over many square miles of country
these conditions are exactly reversed, and such very "ancient" rocks as
Cambrian limestones are on top of the comparatively "young" Cretaceous,
while the lime between them "acts exactly like the line of contact of two
nearly horizontal formations," and in a natural section made by a river the
two "appear to succeed one another conformably." To any one ignorant
of the theory of life succession they have every appearance of having been
deposited as we find them.
(4) That the rivers of the world, in cutting across the country, completely
ignore the varying ages of the rocks in the different parts of their
courses, and act precisely as if they began sawing at them all at the same
time.
Now I know not what additional fact can be demanded or imagined to
complete the demonstration that there is no particular order in which the
fossils can be said to occur as regards succession in time. It is true, some
fossiliferous deposits, metamorphosed almost beyond recognition, and buried
deep beneath thousands of feet of subsequent deposits, have enough appearance
of remote antiquity about them in all conscience. But to increase this
antiquity by saying that other equally prodigious masses of rocks elsewhere
were deposited long after these, or by pointing to still other deposits in another
region which are said to be older than any of the others, is an illogical
and wholly unscientific procedure. I fear I could scarcely confine myself
within the bounds of parliamentary language were I to attempt to express
an opinion regarding any effort that may now be made to justify the life
succession theory in view of the above acknowledged facts.
And surely it is scarcely necessary in this enlightened age to point out
how completely this vitiates any biological argument (such as that of Darwinism)
which has incorporated into its system the results of such illogical
reasoning, or which in any way is dependent upon the conclusions of such a
theory of geology. In view of the laws of evidence, which every intelligent
person is supposed to understand now-a-days, surely some strange things
passed for scientific proof during the nineteenth century. For, as we have
seen, the earlier geologists did little better than assume the succession of
life bodily; than Agassiz and his contemporaries arranged the details and
the exact order of these successive life forms by comparison with the embryonic
life of the modern individual; and now the evolutionists of our day,
led by such men as Spencer and Haeckel with their "phylogenetic principle,"
prove their theory of evolution by showing that the embryonic life of the
modern individual is only "a brief recapitulation, as it were, from memory,"
of the (assumed) geological succession in time. Surely this will some day
make a more amazing record for posterity than those of phlogiston or the
epicycles of Ptolemy.
If I am now asked: What do the rocks have to tell us, in view of the
fact that they refuse to testify to a life succession? I can only say that we
are not as yet in a position to decide this question. There are several other
matters connected with the character and mode of occurrence of the fossils,
which are almost equally important with anything already considered, in
forming a true scientific induction regarding this matter. These facts must
be considered in subsequent chapters. Already, however, we can say this
much, that we have in the rocks almost as complete a world, in some respects
vastly more complete, than the living world of to-day. With the life
succession theory repudiated, we have still to deal with the fossils themselves
which have been thus systematically classified; but this geological
series becomes only the taxonomic or classification series of an older state
of our present world, buried somehow and at some time or times in the
remote past—the how and the when of which we have not as yet the means
to determine.
But I think we are now prepared to enter the mazes of the biological
argument, and to study the subject of extinct species, which by many is supposed
to furnish a line of independent evidence in favor of the life succession
theory.
Let us now test the value of this assumed life succession by another
very simple question. In "Eocene times," so we are told, England was a
land of palms, with a semi-tropical flora and fauna. In fact at this time,
cycads, gourds, proteads (like the Australian shrubs and trees), the fig,
cinnamon, screw-pine, and various species of acacias and palms, abounded
in England and Western Europe; while turtles, monkeys, crocodiles, and
other sub-tropical and warm-temperate forms were equally abundant. Then
again, in the Pleistocene deposits of the same countries, we find various
species of elephant and rhinoceros, with a hippopotamus, lion, and hyena,
identical with species now living in the tropics, "although," as Dana says,
"these modern kinds are dwarfs in comparison."
Now, how are we to prove that these various forms of animal life did not
exist together in these countries at the same time as the trees and plants
before mentioned?
Lions and monkeys, hippopotami and crocodiles, with elephants, hyenas,
and rhinoceroses, now live beneath the palms, mimosas, acacias, and other
tropical plants represented in the Eocene and Miocene beds. What is there
to hinder us from believing that they all lived there together in that olden
time? Surely it would be the very irony of scientific fate if forms now so
closely connected in life should in death be so divided. Or, to present it in
another form, why should we be asked to believe that these acacias, cinnamons,
palms, etc., lived and died ages or millions of years before the lions,
elephants, rhinoceroses and hippopotami, came into existence to enjoy their
shade; and then, after these unnumbered ages had dragged their slow length
along and vanished into the dim past, and all these semi-tropical plants had
shifted to the tropics or been turned into lignite, these lions, elephants, and
hippopotami came into existence in these same localities, when no such
plants existed anywhere in Europe?
Surely we ought to expect some pretty substantial evidence for such a
violation of "the observed uniformity of nature." We generally boast that
we have outgrown the crude ideas of the earlier years of the science when
they spoke of "ages" of limestone making or of sandstone making; but it
seems that some of us have not yet attained to that broad view of the
essential unity of nature in which the flora and fauna of our world are seen
to be just as indissolubly connected with each other. But nature could as
easily be persuaded to produce for a whole age nothing in the way of rock but
limestone or conglomerate, as to adjust her powers to such an unbalanced
state of affairs as is spoken of above, with the animals in one age and the
complementary plants in another.
But in considering this question as to why the Eocene plants and the
Pleistocene animals may not be supposed to have lived contemporaneously
together, we are brought face to face with the second supposed argument in
favor of there having been a succession of life on the globe. The answer
given is that all the animals of these "early" Tertiary beds are extinct
species, also very many of the plants; while the hyena, lion, hippopotamus,
etc., of the Pleistocene are identical with the living species, and even the
mammoth is so closely like its nearest surviving relative, the Asiatic elephant
(E. indicus), that these also might be classed as identical.[33]
This point being considered by many as so important, and having such
a vital connection with the whole life succession theory, we must go into
the matter somewhat in detail, even at the risk of appearing rather technical
to some.
If the Palaeozoic and Mesozoic strata are often of enormous extent,
spreading in vast sheets over wide regions, so that their stratigraphical
order in any particular district is quite readily made out, it is in most cases
altogether different with the Tertiary and Pleistocene deposits. For these
resemble one another so much in everything except their fossils, and occur
so generally in detached and fragmentary beds, holding no stratigraphical
relation to one another, that Lyell devised the plan of distinguishing them
from one another and arranging them in the accustomed order of successive
ages, by their relative percentages of living and extinct mollusca. With
only unimportant changes, Lyell's divisions are still followed in classifying
off the Tertiary and post-Tertiary beds. Those with all the species extinct,
or less than 5 per cent. living, are classed as Eocene; those containing few
extinct forms, or nearly all living species, are classed as Pleistocene or post-Tertiary.
The Miocene and Pliocene represent the intermediate grades,
and all are supposed to be a true chronological order. It goes without saying
that in actual practice it is often so extremely difficult to adjust these
differences that beds are assigned to an "early" or a "late" division on
general principles by what the literary critics would call "tact" or "intuition,"
rather than by the strict percentage system, though for these large and
important divisions of Tertiary and post-Tertiary rocks, these are absolutely
the only professed grounds on which the subdivisions are distinguished and
arranged in the customary order of time.
In the words of Dr. David Page:
"As there is often no perceptible mineral distinction between many
clays, sands and gravels, it is only by their imbedded fossils that geologists
can determine their Tertiary or post-Tertiary character."[34]
Now to say that a set of beds, ninety-five per cent. of whose fossils
belong to extinct species, and only five per cent. are now living, must be
vastly older than another set where these percentages are reversed, i.e.
where the species are nearly all living, seems at first thought an eminently
reasonable idea, and we immediately begin to imagine the long ages it must
have taken for these exceedingly numerous and apparently vigorous species
to wear out and become extinct in the alleged ordinary way by the merciless
struggle for existence with forms more fitted to survive.
But it is hardly necessary to point out that all this is based on the assumption
of Uniformity in its most extreme type, a doctrine which not only
denies that these living forms are merely the lucky survivors of tremendous
changes in which their contemporaries perished, but which in essence is
taking for granted beforehand the very point which ought to be the chief
aim of all geological inquiry, viz., How did the geological changes take
place? It would not be considered a very scientific procedure for a coroner,
called upon to hold a post mortem, to content himself with interesting statistics
about the percentage of people who die of old age, fever, and other
causes, while there was clear and decisive evidence that the poor fellow had
been shot. In this case, as in geology, it is not merely the result that is
wrong, but the whole method of investigation. For, as in the latter case we
don't want to know how people generally die, but how this particular person
actually did die, so, in our study of geology, we do not wish to know merely
the rate at which changes of surface and extinctions of species are now
going on, and then project this measure backward into the past as an infallible
guide, but we wish to know for sure just what changes of this nature
have taken place. A true induction is, I think, capable of deciding very
positively whether or not the tools of nature have always worked at the
same rate and with the same force as at present; and this method of arranging
the fossils in supposed chronological order on the percentage basis
mentioned above, is only an extreme form of methods claiming to be inductive
which in this age of the world ought to be considered a shame and a
disgrace, because, as Howorth says, they are based, "not upon induction,
but upon hypotheses," and have "all the infirmity of the science of the
Middle Ages."
Then again, it occurs to us, that this method, of attaching a time-value
to percentages of extinct or living species, would make the sub-fossil
remains of the bison on the Western prairies almost infinitely older than
those of the lion, hippopotamus, etc., in the Pleistocene beds of Europe;
for (except for some few specimens artificially preserved, and which may
be ignored in this connection) the bison is to-day absolutely extinct, while
the Pleistocene mammals are found by the thousand in the proper localities
and show no signs of surrender in the struggle for existence. Similar comparisons
might be made between the great wingless birds of Madagascar,
Mauritius and New Zealand, and the many cases of "persistent" forms
which have survived unchanged from Carboniferous, Silurian, or Cambrian
times, a period of time which, in the language of the current geology, means
quite a large fraction of eternity. But all of these considerations show that
the mere fact of certain species being extinct and others being now alive,
is no trustworthy guide in determining the relative age of their remains, until
we first find out how they happened to become extinct.
The inquiry as to the how and the when (relatively) is an absolutely
essential preliminary in any such investigation; and is inseparably united
in nature with the general question of how the great geological changes
have taken place in the past. Of course, if everything like a world-catastrophe
is a priori denied; if, in other words, it is settled from the first that
all these fossils living and extinct did not live contemporaneously with each
other, the living ones being simply the lucky survivors of stupendous changes
in which the others perished, then all pretense of a scientific investigation
of the subject is at an end. If a coroner has it settled beforehand that an
accident or a murder could not possibly have occurred, then his profession
of a candid post mortem examination is only a farce; for he does not hold it
to find out anything, since he knows everything essential about it beforehand.
Uniformitarians would certainly make poor coroners, or for that
matter poor investigators of law or history, or anything else.
Will some one please give us a reasonable explanation of why the lion,
hippopotamus, rhinoceros, and elephant shifted from England to the tropics?
Or will they explain how, at this same general time, some elephants and
rhinoceroses got caught in the merciless frosts of Northern Siberia so suddenly
that their flesh has remained untainted all these centuries, and is
now, wherever exposed, greedily devoured by the dogs and wolves?
An abundant warm-climate vegetation once mantled all the polar regions,
and its fossils have been found just about as far north as explorers have
ever gone; while Dana says that, "The encasing in ice of huge elephants,
and the perfect preservation of the flesh, shows that the cold finally became
suddenly extreme, as of a single winter's night, and knew no relenting afterwards."[35]
Now, if no one can deny this sudden change of climate over half the
world or so at least, is it not extremely unscientific to deny that this same
cause, whatever it may have been, was quite competent to bring about a
good many other changes, and the extinction of numerous other species
which we are so often reminded must imply the lapse of untold ages of time?
The economizing of energy, or the famous law of parsimony as stated by
Leibnitz, is quite appropriate in this case, and may be referred to again in
the sequel. The principle upon which I must here insist is that the mere
fact of certain species being extinct, and others being now alive, gives no
clue whatever to the relative age of these remains, until we first ascertain
why, how and when this extinction was brought about. And yet, though every
one admits the fact of tremendous changes of climate, etc., having intervened
between that ancient world and our own (the true extent and character
of which, as I have said, ought to be the chief point of all geological
investigation), no allowance seems ever to be made for this as a powerful
cause of extermination of all forms of life. But in the utter absence of any
such explanation as to how and when, and in the very teeth of these facts
assuming a dead-level uniformitarianism, the presence of ten, fifty or a
hundred per cent. of extinct forms in a set of beds is manifestly of no
scientific value in determining age. It would be many degrees more reasonable
and accurate to arrange all the Greek and Latin books of the world in
chronological order according to the percentage of their words which have
survived into the English language. Indeed, it would be much like a coroner,
at the inquest following a railway disaster, attempting to arrange the exact
order in which the various victims had perished by the proportionate number
of surviving relatives which each had left behind him.
And the completely worthless character of such "evidence" of age becomes,
if possible, more apparent when we consider that very many of these
so-called "extinct" forms are not really distinct species from their living
representatives of to-day. "It is notorious," says Darwin, "on what excessively
slight differences many palaeontologists have founded their species."
And even to-day, in spite of all that we have learned about variation, little or
no allowance seems ever to be made for the effects of a certainly greatly
changed environment. If the fossil forms among the mollusks and other
shell fish for instance, are not precisely like the modern ones in every respect,
they are always classed as separate species, the older forms thus
being "extinct," in utter disregard of the striking anatomical differences between
the huge Pleistocene mammals and their dwarfish descendants of to-day,
which for a hundred years or so were declared positively to be distinct
from one another, but are now acknowledged to be identical.
Of course no one denies that there are numerous extinct forms among
the invertebrates, just as we know there are among the huge vertebrates
of the Mesozoic and Tertiaries, none of which we moderns have ever seen
alive. Other forms do not appear familiar to our modern eyes, because larger
or of somewhat different form; but to say that they are really distinct
species from their modern representatives, or to say that no human being
ever saw them alive, are statements utterly incapable of proof. Up to
about the year 1869 it was stoutly maintained that man had never seen any
of these fossil forms in life. But no one now maintains this view, for
human remains have now been found along with undisturbed fossils of the
Pleistocene, or even middle Tertiaries, while the paintings on the cave
walls of Southern France seem conclusive that they were copied from life
when the mammoth and reindeer lived side by side with man in that latitude.
Hence the only question now is, and it is the supreme question of all
modern geology, WITH HOW MUCH OF THAT ANCIENT FOSSIL WORLD
WERE THESE EQUALLY FOSSIL MEN ACQUAINTED? If Man lived in
"Pliocene" or perhaps "Miocene times," when a luxuriant vegetation was
spread out over all the Arctic regions, what possible evidence is there to
show that his companions, the rhinoceros, hippopotamus, mammoth, etc.,
were not also living then and browsing off just such plants, when the Arctic
frosts caught them in the grip of death and put their "mummies" in cold
storage for our astonishment and scientific information? Things which are
equal to the same thing are equal to each other; why should not the plants
and animals, contemporary with the same creature (man), be just as truly
contemporary with one another? If man was contemporary with the Miocene
plants, and the Pleistocene mammals were contemporary with man, what
is there to forbid the idea that the Pleistocene mammals and the middle
Tertiary flora were contemporary with each other?
For nearly half a century geologists have never had the courage to face
this problem fairly and squarely, with all preconceived prejudices about
uniformity cast aside. Is it possible that all the plants and animals of the
Tertiaries and the Pleistocene may have really lived together in the same
world after all? But the trouble would then be that, with this much conceded,
the whole "phylogenic series" would tumble with it, and become
only the taxonomic or classification series of that ancient world with which
these fossil men were acquainted. To appropriate the words of one who
has done much to clear the ground for a common-sense study of geology,
I know of nothing against such an idea save "the almost pathetic devotion of
a large school of thinkers to the religion founded by Hutton, whose high
priest was Lyell, and which in essence is based on a priori arguments like
those which dominated Mediaeval scholasticism and made it so barren."[36]
Baron Cuvier's work in the line of comparative osteology has never
been surpassed, perhaps never equalled since, and he is said to have been
"the greatest naturalist and comparative anatomist of that, or perhaps of
any time." (LeConte, "Evol. and Rel. Thought," pp. 33, 34); and yet he
maintained till the last that all those which we now call the Pleistocene
mammals were distinct species from the modern ones; and it is only of
recent years and with extreme reluctance that many of them have been admitted
to be identical with the ones now living. All of which tends to show
how unreliable are those assertions commonly found in the text-books
about all the species of the so-called "older" rocks being extinct. It is only
with hesitation that such specific distinctions are surrendered even to-day,
though during the last few decades a steady progress has been made in
bringing the palaeontology of the higher vertebrates into line with our increased
knowledge of zoology, thus breaking down many of the specific
distinctions which have long been maintained between the fossil and the
living forms. Even the mammoth has been found to have so many characters
identical with the modern elephant of India, and such a complete gradation
exists between the two types, that Flower and Lydekker acknowledge
the transition from one to the other is "almost imperceptible," and express
a doubt whether they "can be specifically distinguished" from one another.[37]
But the extreme reluctance with which anything like a confession of
this fact leaks out in our modern literature can be readily understood when
we try the hopeless task of splicing the environment of the modern form
with that of the ancient on any basis of uniformity.
Zittel gives us a peep behind the scenes which helps us to appreciate
the value of a percentage of extinct species as a test of the age of a rock
deposit.
He pictures the uncritical work of the earlier writers on fossil botany,
until August Schink (1868-91) made a great reform in this science; and
Zittel declares that "now the author of a paper on any department" of fossil
botany "is expected to have a sound knowledge" of the systematic botany of
recent forms. But he adds: "It cannot be said that palaeozoology (the
science of fossil animals) has yet arrived at this desirable standpoint."
But he justifies this charge of want of confidence by saying:
"Comparatively few individuals have such a thorough grasp of zoological
and geological knowledge as to enable them to treat palaeontological researches
worthily, and there has accumulated a dead weight of stratigraphical-palaeontological
literature wherein the fossil remains of animals
are named and pigeon-holed solely as an additional ticket of the age of a
rock-deposit, with a willful disregard of the much more difficult problem of
their relationships in the long chain of existence.
"The terminology which has been introduced in the innumerable monographs
of special fossil faunas in the majority of cases makes only the slenderest
pretext of any connection with recent systematic zoology; if there
is a difficulty, then stratigraphical arguments are made the basis of a solution.
Zoological students are, as a rule, too actively engaged and keenly
interested in building up new observations to attempt to spell through the
arbitrary palaeontological conclusions arrived at by many stratigraphers, or
to revise their labors from a zoological point of view."[38]
Doubtless this scathing impeachment of the common mania for creating
new names for the fossils has especial reference to the case of the lower
forms of life. For if, in spite of the brilliant and withal careful work of
Cuvier, Owen, Wallace, Huxley, Ray Lankester, and Leith Adams, with
numerous others that might be mentioned, there are still grounds for such
grave doubts of the values of specific distinctions in the case of the mammals,
whose general anatomy and life-history are so well known and their
almost countless variations so well studied out, what must be the confusion
and inaccuracy in the case of the lower vertebrates, and especially of the
invertebrates, whose general life-history in so many instances is so dimly
understood, and the limits of their variations absolutely unknown? Remembering
all this, what is our amazement when we read in this same
volume by Professor Zittel[39] that the tendency among many modern writers
in dealing with these lower forms of life, is toward the erection of the
closest possible distinctions between genera and species, until recent palaeontological
literature is fairly inundated with new names; and all this
with the purpose, unblushingly avowed, of "enhancing the value" of such
distinctions as a means of determining the relative ages of strata, and to
"bring the ontogenetic and phylogenetic development" of the various forms
"into more apparent correspondence." I do not exaggerate in the least, as
the reader may see by referring to Zittel's book; though not wishing to
make my readers "spell through" another quite technical paragraph I have
refrained from direct quotation.
But surely we have here a most amazing style of reasoning. It is another
clear case of first assuming one's premises, and then proving them by
means of one's conclusion. The method here employed seems about like
this: First assume the succession of life from the low to the high as a
whole; then in any particular group, as of Brachiopods or Mollusks, decide
the momentous question as to which came first and which later in "geological
time" by comparing them as to size, shape, etc., with the live
modern individual in its development from the egg to maturity; and lastly,
take the results of this alleged chronological arrangement to prove just how
the modern forms have evolved. Surely it is a most fearful example of
otherwise intelligent men being hypnotized by their theory into blind
obedience to its suggestions and necessities.
Not long ago I had occasion to write to a well-known geologist about
a Lower Cambrian mollusk which appears strikingly like a modern species.
I give below an extract from his reply which bears directly upon this
point. I withhold the name, for the information was given in a half-confidential
manner, but I may say that the author's work on the Palaeozoic
fossils is recognized on both sides of the Atlantic.
"Some geologists make it a point to give a new name to all forms found
in the Palaeozoic rocks, i.e. a name different from those of modern species.
I was taken to task by a noted palaeontologist for finding a pupa (a kind of
land snail) in Devonian beds; but I could not find any point in which it differed
from the modern genus [? species]. Yet if I could have had more perfect
specimens I might have found differences."
Such disclosures speak volumes for those able to understand; and lead
one to receive with a smile the familiar assertion that all the species of the
Palaeozoic and other "older" rocks are extinct. And we can now form a
truer estimate of the high scientific accuracy of Lyell's ingenious division
of the Tertiary beds, according to the percentage of living or extinct Mollusks
which they contain.
But from the inherent weakness of the argument about extinct species
as thus revealed, it follows that chronological distinctions based on any proportionate
number of extinct species have absolutely no scientific value; and
hence that the life succession theory finds no support from these chronological
distinctions, just as we have already seen that it is without a vestige
of support from the stratigraphical argument.
The life succession theory has not a single fact to confirm it in the
realm of nature. It is not the result of scientific research, but purely the
product of the imagination.
We have now to deal with another absurdity involved in the life succession
theory, the discussion of which grows naturally out of the subject of
extinct species.
As preliminary to the subject here to be presented, we must bear in
mind that the present arrangement of the fossils in alleged chronological
order, as well as the naming of thousands of typical specimens, was all well
advanced while as yet little or nothing was known of the contents of the
depths of the ocean, or even of the land forms of Africa, Australia, and
other foreign countries. In most of the important groups of both plants and
animals, the detailed knowledge of the fossil forms preceded the knowledge
of the corresponding living forms, just as Zittel says that the theories of the
igneous origin of the crystalline rocks "had been laid without the assistance
of chemistry" and the knowledge of the microscopic structure of these
rocks.[40] On pp. 128-137 of his "History," this author shows how, up to 1820,
little or nothing of a scientific character was known of any of the classes
of living animals save mammals. During the last half century, however,
the progress of science has been steadily showing case after case where
families and genera, long boldly said to have been "extinct" since "Palaeozoic
time," are found in thriving abundance and in little altered condition in
unsuspected places all over the world. And the point for consideration
here is the manifest absurdity of these inhabitants of the modern seas and
the modern land skipping all the uncounted millions of years from "Palaeozoic
times" down to the "recent," for, though found in profuse abundance
in these "Older" rocks, not a trace of many of them is to be found in all
the "subsequent" deposits.
The proposition here to be considered and proved I shall venture to
formulate as follows:
There is a fossil world, and there is a modern living world; the two resembling
one another in various details as well as in a general way; but to
get the ancestral representatives of many modern types, e.g., countless invertebrates,
with other lower forms of animals and plants, we must go clear
back to the Mesozoic or the Palaeozoic rocks, for they are not found in any
of the "more recent" deposits.
I have already remarked that the blending of the doctrine of life succession
with that of uniformity, must inevitably have given birth to the
evolution theory, for it is evident that the succession from the low to the
high could only have taken place by each type blending with those before
and those after it in the alleged order of time. That such is not the testimony
of the rocks, even when arranged with this idea in view, is too notorious
to need any words of mine, for it has been considered by many[41] the
"greatest of all objections" to the theory of evolution.
This abruptness in the disappearance of "old" and the first appearance
of "new" forms, has brought into being that "geological scape-goat," as
James Geikie has called the doctrine of the imperfection of the record. But
Dawson has well disposed of this argument in the following words:
"When we find abundance of examples of the young and old of many
fossil species, and can trace them through their ordinary embryonic development,
why should we not find examples of the links which bound the species
together?"[42]
But it is equally evident that each successive series ought to contain,
in addition to its own characteristic or "new" species, all the older forms
which survived into any later deposits, or are now to be found living in our
modern world. Such no doubt was the idea of those of the early geological
explorers who discarded Werner's onion-coat theory, and they tried to arrange
their series accordingly. This reasonable demand is still recognized
as good; and the principle is alluded to by Dana when he attempts to show
how strata might be discovered and "proved" to be older than the present
Lower Cambrian rocks.[43]
It is, I say, still recognized in theory that the "younger" deposits ought
to contain samples of the "older" types which were still surviving, in addition
to their own characteristic species; but with the progress of geological
discovery it has long since been found that such an arrangement was utterly
impossible. Indeed, it would almost seem as if modern writers had forgotten
the principle altogether.
For, as already said, according to the present chronological arrangement,
many kinds of invertebrates, both terrestrial and marine, occurring
in comparative abundance in our modern world, are found as fossils only
in the very "oldest" rocks and are wholly absent from all the rest!!! Others
which date from "Mesozoic times" are wholly absent from the Tertiaries,
though abundant in our modern world. This I regard as another crucial
test of the rationality of this idea of a life succession.
Of course there are certain limitations which must be borne in mind.
If we find a series of beds made up largely of deep sea deposits, we cannot
reasonably expect to find in them examples of all the land forms of the
preceding "ages" which then survived, nor even of the shallow water types.
Nor, conversely, can we demand that, in beds crowded with the remains
of the great mammals and plants, and thus probably of fresh or shallow
water formation, we ought to find examples of all the marine types still
surviving. We now know that each level of ocean depth has its characteristic
types of life, just as do the different heights on a mountain side. This
doctrine of "rock facies" was, I believe, enunciated first in 1838. Edward
Forbes also did much for this same idea, showing how at the present time
certain faunas are confined to definite geographical limits, and particular
ocean depths. Jules Marcou about 1848 applied this principle to the fossils
and showed how such distinctions must have prevailed during geological
time.
Here it seems that we are at last getting a refreshing breath of true
science; but if carried out in its entirety how shall we assure ourselves that
in the long ago very diverse types of fossils, e.g., gratolites and nummulites,
or even trilobites and mammals, could not have been contemporary with
each other? This principle of "rock facies," if incorporated into the science
in its early days, would have saved the world from a large share of the
nonsense in our modern geological and zoological text-books.
But in answer to any pleadings about the imperfection of the record,
or any protests about the injustice of judging all the life-forms of an "age"
by a few examples of local character, i.e., of fresh, shallow, or deep water
as the case may be, the very obvious retort is, Why then are such local and
fragmentary records given a time value? Why, for example, should the
Carboniferous and associated formations be counted as representing all the
deposits made in a certain age of the world, when we know from the Cambrian
and Silurian and also from the alleged "subsequent" Jurassic that
there must have been vast open sea deposits formed contemporaneously?
As Dana expresses it:
"The Lias and Oolyte of Britain and Europe afforded the first full display
of the marine fauna of the world since the era of the Subcarboniferous.
Very partial exhibits were made by the few marine beds of the Coal measures:
still less by the beds of the Permian, and far less by the Triassic.
The seas had not been depopulated. The occurrence of over 4,000 invertebrate
species in Britain in the single Jurassic period is evidence, not of
deficient life for the eras preceding, but of extremely deficient records."[44]
Surely these words exhibit the "phylogenic series" in all its native, unscientific
deformity. It is because the Coal-measures, the Permian, and
the Triassic, are necessarily "extremely deficient records" of the total life-forms
then in the world, that I am writing this chapter, and this book. But
it seems like perverseness to plead about the imperfection of the record,
and yet refuse the evidently complementary deposits when they are presented.
If, as this illustrious author says, "The seas had not been depopulated,"
what would he have us think they were doing? Were they forming no
deposits all these intervening ages that the Carboniferous, Permian, and
Triassic were being piled up? Were the fishes and invertebrates all immortalized
for these ages, or were they, when old and full of days translated
to some supermundane sphere, thus escaping deposit in the rocks? Did the
elements continue in the status quo all these uncounted millions of years?
and if so, how did they receive notice that the Triassic period was at last
ended, and that it was time for them to begin work again? I do not like
to appear trivial; but these questions serve to expose the folly of taking
diverse, local, and partial deposits, and attaching a chronological value to
each of them separately, and then pleading in a piteous, helpless way about
the imperfection of the record.
And yet I cannot promise to present a tithe of the possible evidence,
because of two serious handicaps. First, the ordinary literature of the
science is silent and meagre enough in all conscience, even though the bare
fact may be recorded that a "genus" of the Cambrian or Silurian is "closely
allied" to some genus now living. It may be even admitted that "according
to some it is not genetically distinct from the modern genus" so-and-so; but
the authors never descend below the "genus," and in most cases forget to
tell us whether or not it occurs in other "later" formations, though of course
the presumption is that it does not, but has skipped all the intervening
ages, or it would hardly be named as a characteristic type of the formation
in which it occurs.
But this disadvantage, serious though it be, is scarcely worth speaking
of when we remember the significant words of a well-known authority already
quoted:
"Some geologists make it a point to give a new name to all forms found
in the Palaeozoic rocks, i.e. a name different from those of modern species."
Or Zittel's confession that:
"The terminology which has been introduced in the innumerable monographs
of special fossil faunas in the majority of cases makes only the
slenderest pretext of any connection with recent systematic zoology; if
there is a difficulty, then stratigraphical arguments are made the basis of
a solution. Zoological students are as a rule too actively engaged and
keenly interested in building up new observations to attempt to spell through
the arbitrary palaeontological conclusions arrived at by many stratigraphers,
or to revise their labors from a zoological point of view."
Hence I have no reluctance in saying that, in the present confused
state of the science, it is utterly impossible to find out the truth as to how
many hundreds of these "genera" of the Paleozoic rocks may have survived
to the present, though having skipped perhaps all the formations
of the intervening millions of years. I doubt not that the number is
enormously large, though as I have not attempted "to spell through the
arbitrary palaeontological conclusions" scattered through the literature,
I can only depend on a few though striking examples that lie on the open
pages of the ordinary text-books.
The larger mammals can of course furnish us no examples, for the
"age" in which they abounded is quite conveniently modern, and is separated
from the present by no great lapse of time. Of the smaller marsupials,
quite a number of jaw-bones have been found in the Jurassic and
Triassic, one from the latter being strikingly like the living Myrmecobius
of Australia. They are scarcely more numerous in the Cretaceous of
America, while in the foreign rocks of this system Dana says that "Only
one species had been reported up to 1894." Those strange, sad-eyed creatures
called Lemurs deserve a passing notice, for though now confined
as to their typical forms to the island of Madagascar, their fossils seem
as exclusively confined to the temperate regions of the New and the Old
World. Flower and Lydekker enumerate about fifteen fossil species, and
add that:
"... it is very noteworthy that all these types seem to have disappeared
from both regions with the close of the upper portion of the
Eocene period."[45]
But this jump from the "Eocene period" to the present is as nothing
compared with the secular acrobatics of some of the fishes and especially
of the invertebrates. The living Cestraciont sharks, of which there are
four species found in the seas between Japan and Australia, seem to disappear
with the Cretaceous, skipping the whole Tertiary Epoch, as do also
a tribe of modern barnacles which, as Darwin says, "coat the rocks all
over the world in infinite numbers." The Dipnoans or Lung-fishes (having
lungs as well as gills, such as the Ceratodus and Lepidosiren), which are
represented by several living species in Australia and South Africa, are
the remains of a tribe found in whole shoals in the Carboniferous, Triassic
and Jurassic rocks, but not, so far as I know, in any of the intervening
rocks. The living Ceratodus was only discovered in 1870, and was regarded
as a marvel of "persistence." On a pinch, as when his native streams
dry up, this curious fellow can get along all right without water, breathing
air by his lungs like a land animal. If in the meantime he was off on a
trip to the moon, he must have "persisted" a few million years without
either.
But his cousin, the Polypterus of the Upper Nile, has a still more
amazing record, for he has actually skipped all the formations from the
Devonian down to the modern; while the Limuloids or sea scorpions have
jumped from the Carboniferous down.
The Mollusks and Brachiopods would afford us examples too numerous
to mention. How is it possible that these numerous families disappear suddenly
and completely with the Mesozoic or even the "early" Palaeozoic,
and are not found in any "later" deposits, though alive now in our modern
world? Parts of Europe and America have, we are told, been down under
the sea and up again a dozen times since then; why then should we not
expect to find abundant remains of these "persistent" types in the Mesozoic
and Tertiaries? Surely these feats of time-acrobatics show the folly of arranging
contemporaneous, taxonomic groups in single file and giving to
each a time value.
The Chalk points a similar lesson. It was not till the time of the
"Challenger" Expedition that the modern deposits of Globigerina ooze, made
up of species identical with those of the Chalk, were known to be now
forming over vast areas of the ocean floor. In the words of Huxley, these
modern species "bridge over the interval between the present and the
Mesozoic periods."[46]
As for the silicious sponges found in the Chalk, which were such
puzzles for the scientists during the first half of the nineteenth century,
because their living forms were unknown, the deep-sea investigations have
solved the problem, for in 1877 Sollas demonstrated "the identity of their
structure with that of living Hexactinellids, Lithistids, and Monactinellids."[47]
And yet with all the alleged vicissitudes of the continents during the
millions of years since the Cretaceous age, there is so far as I am aware
not a trace of either the chalk or the sponges in any of the "subsequent"
rocks. Pieces of Cretaceous rock are of course found thus sporadically
as boulders, but there is no natural deposit of this kind. But in the light
of these modern discoveries why is not the Chalk of "the white dear cliffs
of Dover," full of modern living species as we now know it to be, just as
"recent" a deposit as the "late" Tertiaries or the Pleistocene?
Another good illustration of the absurdity of the present arrangement
of the rocks is found in the Echinoderms—crinoids, star-fishes, sea-urchins,
etc. Of the latter Prof. A. Agassiz found in the deep waters of the West
Indies, four genera of Echinids or sea-urchins of the "later Tertiary," but
24 genera of the "early" Tertiary, 10 of the Cretaceous, and 5 of the Jurassic.[48]
But far from being uncommon we know that similar discoveries have
been in almost constant progress during the last half century. And were
it not that "zoological students are," as Zittel says, "too actively engaged and
keenly interested in building up new observations to attempt to spell
through the arbitrary palaeontological conclusions" found in the "dead
weight of stratigraphical-palaeontological literature," there is no telling
what hosts of similar facts might not be pointed to regarding the forms
found in all the "older" rocks.
Of the star-fishes and serpent-stars (Asteridea and Ophiuridea), Zittel
says: "It would seem that the Palaeozoic 'sea-stars' differed very little
from those in the seas of the present age." (p. 395.) The crinoids, we are
told, "are among the earliest in geological history," making up vast limestones
of the Palaeozoic rocks; and forms scarcely separable from the
modern are found in the Jurassic, but so far as the text-books tell us are
absolutely unknown in any later deposits. But there are several modern
genera, such as Pentacrinus, Rhizocrinus, Bathycrinus, etc., found in the
deep waters of nearly all the oceans. The genus Rhizocrinus was discovered
off the coast of Norway about the sixties of the last century. But
what were these creatures doing since "Jurassic times," while the "pulsating
crust" was putting parts of the continents under the sea for ages at a
stretch? Why did they form no deposits during the Cretaceous, Eocene,
Miocene or Pliocene ages? Surely the absurdity of the present arrangement
is evident to a child. During all these intervening ages the climate of the
globe continued of the same remarkable mildness, fossils of all these formations
being found about as far north as explorers have ever gone. Why
did the crinoids and polyp-corals suspend business from "Jurassic times"
to the "recent," merely to accommodate a modern theory? Dana says that
"The coral reefs of the Oolyte in England consist of corals of the same
group with the reef-making species of the existing tropics,"[49] and he argues
from this fact that the mean temperature of the waters must have been
about 69 deg. F. But a luxuriant vegetation still continued in the Arctic
regions during the Cretaceous and the Tertiaries. How absurd to say that
these corals built no reefs about the European coasts during all these ages.
Or, to put the matter in another way, considering how many of their characteristic
types are alive in our modern seas, why should we say that the
crinoidal or coral limestones of the Mesozoic or Palaeozoic rocks are not
as recent as the nummulitic limestones of the Eocene or any late Tertiary
deposits?
It is no answer at all to tell us that, though the general types are the
same, the species of the Palaeozoic and the Mesozoic are entirely extinct.
I have not had the courage "to attempt to spell through" all the "dead
weight" of the modern literature, but I think that the world would like
more satisfactory proof of this oft-repeated assertion than the customs and
traditions of a hundred years, and the exigencies of a fanciful theory.
This worn-out argument of Cuvier's about extinct species has kept up a
running fight with common sense for many decades, and though driven
backward from one point to another over the long thin line of this taxonomic
series of the fossil world, it still contests every inch of ground.
But let us try the tree-ferns and cycads of the coal beds of the "older"
rocks. In northern regions they are not found "later" than the Triassic
and Jurassic, and doubtless the same holds good of the rocks in the Tropics,
where the modern species now live in fair abundance. But how did they
come to shift to the Tropics so many millions of years before the palms,
etc., of the Tertiaries thought it time to do the same? The climate had
not changed a bit: how did they come to scent the coming "Glacial Age"
so much earlier than their more highly organized fellows?
The "Challenger" expedition found some Cyathophylloid corals now
building reefs at the bottom of our modern ocean. The geologists had
already assigned the last of them to the Carboniferous and Permian rocks
with the idea that they were extinct. But where have these fellows kept
themselves during all the intervening ages while the continents were deep
under the ocean time and time again? or why are not the rocks containing
their fossils as "recent" as any deposits on the globe?
And so I might go on. There is hardly a tribe found in the "older"
rocks which does not have its living representatives of to-day, and with,
I believe, a fair proportion of the species identical; though in hundreds,
perhaps thousands, of cases these species, genera, or even whole tribes, have
somehow skipped all the intervening formations.
But let us drop this method of studying our subject, and look at it from
a slightly different standpoint.
Thus Dana[50] says that:
"The absence of Lamellibranchs in the Middle Cambrian, although
present in both Lower and Upper, means the absence of fossils from the
rocks, not of species from the faunas."
He puts this in italics by way of emphasis, for it is certainly a reasonable
idea, and as A. R. Wallace says, "no one now doubts that where any type
appears in two remote periods it must have been in existence during the
whole intervening period, although we may have no record of it."[51] But
what would be the result if we only extend this idea to its logical conclusion?
It seems to be an effort to avoid one of the absurdities of the onion-coat
theory, without, however, discarding that theory altogether.
In speaking of some corals and crinoids of the Devonian which "were
absent" from some of the divisions of this formation because the conditions
of the seas about New York "were unfavorable," Dana says that "they
were back when the seas were again of sufficient purity."[52]
In his review of these formations he enlarges on this subject:
"At the close of the early Devonian the evidences of clear seas—the
corals and crinoids, with most of the attendant life—disappear, migrating
no one knows whither.... With the variations in the fineness, or other
characteristics of the beds as H. S. Williams has illustrated, the species
vary.... The faunas of each stratum are not strictly faunas of epochs
or periods of time, but local topographical faunas. After the Corniferous
period, corals, crinoids, and trilobites still flourished somewhere, as before,
but they are absent from the Central Interior until the Carboniferous age[53]
opens."
Here we are certainly getting a refreshing breath of common-sense
geology; but what would become of current theories if we enlarge a little
on this idea?
What if the gigantic dinosaurs of the Cretaceous or the equally marvellous
mammals of the "early" Tertiaries of the Western States, described
by Marsh and Cope, and the Pleistocene mammals of other parts of America
and of Europe and Northern Siberia, "are not strictly faunas of epochs or
periods of time, but local topographical faunas?" What if the world-wide
limestones of the Cambrian and Silurian, and the no less enormous or
widespread nummulitic limestones of the Eocene, extending from the Alps
to Eastern Asia, and constituting mountains ten, fifteen, or twenty thousand
feet high—what if these are possibly contemporaneous with one another?
Supposing the coal-measures of Nova Scotia and Pennsylvania, and
the Cretaceous and Tertiary lignites of Vancouver Island, Alberta, and the
Western States are not strictly floras of epochs or periods of time, but local
topographical floras?[54]
But it must be confessed that the logical extension of this broad view
of the fossils, and the projection of our modern zoological provinces and
zones back into the fossil world would mean the death-blow to the life
succession theory, and might have a very disturbing effect upon certain
theories about human origins and other genetic relationships which have
grown quite popular since the middle of the last century.
