The Preparation of Earth for Man: Chapter 10
Catastrophe and Reconstitution
THROUGHOUT THE whole
process of the preparation of the earth for man, there seem to have been not
merely periods of great creative activity but also periods of great destruction.
And these periods of destruction seem to have been related in some way to the
times of creative activity, not causally but as a kind of prelude or
clearing-of-the-decks. Perhaps Agassiz was a little extreme in his view that
there were innumerable such clearings-of-the-decks, believing as he did that
there were at least hundreds of these catastrophes, wiping out every plant and
animal over vast areas of the earth's surface, but he was by no means alone in
recognizing the profound effect such would have upon the earth's
ecology.
Like the other major interruptions in geological history,
they seem to mark real boundaries between the eras, the largest divisions of
geological time. Normal D. Newell of the American Museum of Natural History in
New York has put it this way: (153)
Abrupt paleontological changes at these stratigraphic
levels are real, approximately synchronous, and recognizable at many places in
different parts of the earth where fossiliferous rocks of approximately
similar age are represented and have been carefully
examined.
These are seemingly global events, which "are
characterized by the abrupt dropping out of all the species, most of the genera,
and many of the higher categories (superfamilies, orders, and classes)
characteristic of the times." When the earth settled down again, we seem almost
to be in a new world. Otto H. Schindewolf of Tubingen, who has been particularly
concerned with this problem, noted that in the recovery period the new
categories of life that suddenly appear without antecedents often seem to be
representative of types in the later, more completely occupied world. It looks
as though God was indeed introducing the archtypes that were to mark the new
order, giving them the wide potentials for later diversification that my thesis
proposes.
Newell notes such abrupt changes of scene, especially at
the end of Permian, at the close of the Mesozoic, and just before the present
order of life was introduced. He pointed out that "geologists have long supposed
that rates of evolution and extinction are in some manner influenced by the
ecological changes induced by orogeny (i.e., mountain-building)." But he added:
(154)
In recent years it has become increasingly evident that
orogenic disturbances and associated ecological changes are actually rather
restricted in extent and therefore of minor evolutionary importance....
Evolutionary episodes as revealed in the record of fossils apparently do not
coincide closely with times of mountain building.
When the age of the great cold-blooded reptiles passed
away and warm-blooded animals appeared on the earth in their place, there
actually was one such abrupt discontinuity between the old and the new worlds on
a global scale. Henry F. Osborn observed: (155)
The most dramatic and in many respects the most
puzzling event in the history of life on the earth, is the change which
exterminated this vast array of creatures. These reptiles were in the climax
of specialization and grandeur.... We have no conception as to what world-wide
cause occurred.... We can only observe that the world-wide effect was the
same: the giant reptiles both of sea and land
disappeared.
Some of the proposed explanations could apply readily
enough to the land animals, as for example the diminishing food supply in the
form of plant life. But this does not help very much with respect to those
animals which lived in the sea. Whatever the cause, it was one which operated
equally on land and sea, and it was surprisingly sudden. George Gamow has put
it: (156)
The kingdom of giant reptiles with its innumerable
representatives on the land, in the sea, and in the air, was certainly the
most powerful and extensive animal kingdom during the entire existence of life
on the earth, but it had also a most tragic and unexpected end. During a
comparatively short period towards the end of the Mesozoic Era the
Tyrannosaurus, Stegosaurus, Ichthyosaurus, Plesiosaurus, and all the other
"sauri" disappeared from the surface of the earth as if wiped away by some
giant storm.... The causes that led to such a sudden extinction of the most
powerful animals that ever existed on the surface of our planet have remained
rather obscure.
Not only do we have the evidence, of a negative kind,
that such creatures suddenly vanished from the scene, but we have a more
positive evidence in the existence of so-called animal cemeteries which are
considerably later. These take the form of very extensive beds in which millions
of bones of a very wide variety of species of animals are found indiscriminately
mixed together. In these cemeteries there are the remains of herbivorous as well
as carnivorous animals and the bones of the former apparently show no signs of
having been gnawed. This is a proof that both types of animals perished
together. Furthermore, there is little evidence of weathering, a fact which is
taken to mean that they were buried almost as quickly as they were
destroyed--perhaps by the very agency which destroyed them. And finally the
bones are forcibly intermixed; that is to say, the leg bone of one species may
be found rammed tightly into the eye socket of the skull of another species, a
circumstance which suggests that these creatures were overwhelmed, not merely
suddenly, but violently. Such cemeteries have to be seen to be believed. No
simple explanation such as that the bones of centuries of dead creatures merely
accumulated by being washed into a depression, or that they represent the
after-dinner remains of generations of some particular local predatory species
(such as hyenas for example) will suffice. These bones have not been exposed to
the sun or the air for any length of time prior to burial, nor are they
gnawed.
Newell leaned heavily on the work of Schindewolf (the
importance of whose work, incidentally, has been recognized by G. G. Simpson)
and emphasized the reality of these discontinuities and the widespread nature of
them. And he admitted frankly that they seem (at least in some cases) to be
caused by quite exceptional circumstances, circumstances not commonly observed
at other periods of geological history or often affecting aquatic life as
dramatically as terrestrial life. So exceptional are the circumstances, in fact,
that according to Newell: (157)
Schindewolf believes the best way to explain many of
the innumerable small as well as the few large discontinuities in the fossil
record. . . is by means of catastrophic extinctions and simultaneous creation
of new faunas.
Of course, this kind of explanation is unacceptable to
the great majority of recognized authorities on matters geological. Ernst Mayr
felt that the explanation is really quite simple. (158) He said, "Ultimately
their extinction is due to an inability of their genotype to respond to new
selective pressures," an explanation which sounds impressive but merely pushes
the problem one step further back to the prior question, Why this inability?
There might also be many equally simple answers to this question in terms of
current genetic theory, but the problem still remains as to why such an
inability to respond should suddenly arise in hundreds of thousands of animals
of different categories and all in the same geological time frame. It is not at
all a comparable situation to the somewhat limited but none the less sad
extinction of species which seem to be associated with the propensities for
overkill by early man in his hunting forays, (159) or by the buffalo hunters of
recent memory. These humanly induced extinctions had only a small effect on the
total ecology, comparatively speaking, for they concern only a small number of
species.
Perhaps the most striking extinction of all that is still
essentially unexplained is the one which seems to have immediately preceded the
appearance of true man and which is in some way linked to the coming of the Ice
Age. It is difficult to discuss this particularly disastrous event without
appearing to be overdramatic, and those who constitutionally find any kind of
catastrophism distasteful try hard to play down the quite extraordinary
character of the fossil record from which we must reconstruct the event. This
catastrophe was sudden in the extreme. It was violent. It seems to have been
very widespread. It was accompanied by a fundamental change in climatic
conditions in many parts of the world. It wiped out enormous numbers of animals
of all kinds--large and small, land and aquatic. And it literally marked the end
of a whole world order. Look at some of the facts of the case as set forth by
various authorities since the early years of the last century.
In 1821, Benjamin Silliman of the Department of Geology
at Yale University, wrote of the large number of species which were apparently
overwhelmed in this single catastrophe. He pointed out that whales, sharks,
crocodiles, mammoths, elephants, rhinoceroses, hippos, tigers, deer, horses,
various species of the bovine family, and a multitude of others were found in
strata "in most instances indicating that they were buried by the same
catastrophe which destroyed them all." (160) A contemporary of Silliman's,
Granville Penn, wrote: (161)
The great problem for geological theories to explain is
that amazing phenomenon, the mingling of the remains of animals of different
species and climates, discovered in exhaustless quantities in the interior
parts of the earth so that the exuviae of those genera which no longer exist
at all, are found confusedly mixed together in the soils of the most northerly
latitudes. . . The bones of those animals which can live only in the torrid
zone are buried m the frozen soil of the polar regions.
And to quote one more contemporary, George Fairholme, who
described similar evidence in Italy from the Arno River Valley: (162)
In this sandy matrix bones were found at every depth
from that of a few feet to a hundred feet or more. From the large and more
apparent bones of the elephant, the rhinoceros, the megatherium, the elk, the
buffalo, the stag, and so forth, naturalists were led by the elaborate studies
of Cuvier and other comparative anatomists to the remains of the now living
bear, tiger, wolf, hyena, rabbit, and finally the more minute remains even of
the water rat and the mouse. In some places so complete was the confusion . .
. that the bones of many different elephants were brought into contact, and on
some of them even oyster shells were matted.
Both Darwin and Wallace were impressed by the evidence of
mass destruction just before man appeared. In his Journal of Researches,
the former wrote of his wonder at the picture presented by the fossil record
in South America, which he visited on the voyage of the Beagle in 1845:
(163)
The mind is at first irresistibly hurried into the
belief that some great catastrophe has occurred. Thus, to destroy animals both
large and small in South Patagonia, in Brazil, in the Cordillera, in North
America up to the Behring Straits, we must shake the entire framework of the
globe. Certainly no fact in the long history of the world is so startling as
the wide extermination of its Inhabitants.
His contemporary, Alfred R. Wallace, in 1876 wrote in a
similar vein: (164)
We live in a zoologically impoverished world, from
which all the hugest and fiercest, and strangest forms have recently
disappeared.... Yet it is surely a marvelous fact, and one that has hardly
been sufficiently dwelt upon this sudden dying out of so many large mammalia
not in one place only but over half the land surface of the
globe....
There must have been some physical cause for this great
change, and it must have been a cause capable of acting almost simultaneously
over large portions of the earth's surface.
One of the most thorough students of this last great
catastrophe was Sir Henry Howorth whose works are now virtually unobtainable.
Although his interpretation of the evidence was, and still is, rejected by
geologists committed to Lyell's principle of uniformity, he nevertheless put on
record a tremendous amount of data, much of it gathered at firsthand, which is
not nearly as well known as it should be. In one of his major works, The
Mammoth and the Flood, he collected data regarding the innumerable known
cases of mammoths frozen in northern latitudes, particularly in Siberia. (165)
And yet in spite of this information, which is always very well documented, a
comparatively recent paper by William R. Farrand entitled, "Frozen Mammoths and
Modern Geology," spoke of only some 39 known frozen carcasses, of which only
four are by any means complete; and it never once mentions the books and papers
published by Sir Henry Howorth. (166) To Dr. Farrand, there is no real evidence
of catastrophe in spite of the extraordinary circumstances under which these
giant creatures evidently died. Howorth, however, gives many details which it is
quite impossible, I believe, to account for in any other way than by assuming a
very sudden catastrophe followed almost immediately by intense cold. It
was encouraging to see that a correspondent countered Farrand's statements very
effectively: (167) but Farrand replied with considerable sarcasm, clearly being
on the defensive.
In 1887 Howorth wrote: (168)
In the first place, it is almost certain in my opinion
that a very great cataclysm or catastrophe occurred . . . by which the mammoth
with his companions was overwhelmed over a very large part of the earth's
surface. This catastrophe, secondly, involved a widespread flood of waters
which not only killed the animals but also buried them under continuous beds
of loam or gravel. Thirdly, that the same catastrophe was accompanied by a
very sudden change of climate in Siberia, by which the animals that had
previously lived in fairly temperate conditions were frozen in their flesh
under the ground and have remained there ever since.
When the facts are stated, they are of such a nature as
to be almost incredible and they are drawn from the works of such men as
Wrangell, Strahlenberg, Witzen, Muller, Klaproth, Avril, Erman, Hedenstrom,
Betuschef, Bregne, Gemlin, Brandt, Antermony, Liachof, Kusholof, Chamisso,
Maljuschkin, Ides, Baer, Schmidt, Bell, Tatishof, Middendorf, von Schrenck,
Olders, Laptef, Sarytschef, Motschulsky, Schtscukin, Maydell, besides the
official documents of the Russian Government.
One of the rivers of Siberia that empties into the Arctic
is the Yenessei. Concerning the buried animals revealed in the strata along the
sides of this river, Howorth remarked: (169)
Pallas reports that the mammoth bones which fall out of
the cliffs are so numerous that on decomposing they form a substance called
"osteocolli" or "bone glue." The next great river eastward towards Alaska,
emptying into the Arctic, is the Lena. It is a vast stream which consists of
twists and turns, making a course of over 2000 miles. The natives who live in
the regions of the Lena river make a living travelling up and down the river
in boats, gathering up the ivory tusks that they see sticking out of cliffs
along the river banks and which they find fallen to the edge of the
water.
The number of animals that are buried in Siberia must be
stupendous. Some conception can be obtained from the fact that since A.D. 900
men have made it a business to collect the ivory of the region and sell it in
China, Arabia, and Europe. In one case where a record was secured, Lyddeker
stated that in a period of twenty years tusks from at least 20,000 animals were
taken from the Siberian mines to markets in Europe during the nineteenth
century. (170) Howorth reported what has since been confirmed many times, that
the contents of the stomachs of many of these giants had been examined carefully
and been shown to contain undigested food, composed of leaves of trees now found
in southern Siberia. (171) Microscopic examination of the skins of some of these
animals has since revealed red blood corpuscles. This is thought to be proof,
not only of sudden death, but death due to suffocation either by gas or water.
(172) One particular animal with an undigested meal still in its stomach had
been eating buttercups, sedges, grasses, the beans of wild oxytropis, and young
shoots of fir and pine. In l901 an expedition to Kolomysk was made by some
Russian scientists to convey to St. Petersburg a particularly fine specimen with
hair, skin, and flesh perfectly preserved--which also had the remains of
undigested food in its stomach. (173)

Knight in the American Museum of Natural History, New York City. This is

History.
Perhaps no one single discovery can ever quite convey so
strong an impression of the suddenness and immensity of the catastrophe as one
reported first by Brandt, (174) and subsequently accredited by others, in which
three mammoth mummies were found standing erect and facing north. A
similar discovery was made by Fisher of a single specimen in the same
extraordinary attitude of arrested flight.
We have mentioned the existence of rhinoceroses in a
similar condition. In a letter to Baron Humboldt from the same Professor Brandt
(of St. Petersburg), particulars are given of a rhinoceros obtained by Pallas in
1772 from Wiljiusky (latitude 64º), from the banks of the Wiljiu, a tributary of
the Lena. Brandt wrote concerning it: (175)
I have been so fortunate as to extract from cavities in
the molar teeth of the Wiljiu rhinoceros a small quantity of its half-chewed
food, among which fragments of pine leaves, one half of the seed of a
polygonacious plant, and very minute portions of wood with porous cells or
small fragments of coniferous wood were still recognizable. It was also
remarkable on a close examination of the head, that the blood vessels
discovered in the interior of the mass appeared to be filled, even to the
capillary vessels, with a brown mass (coagulated blood), which in many places
still showed the red colour of blood.
Before considering similar animal cemeteries in other
parts of the world, it might be well to point out that it is not a normal
occurrence to find dead animals anywhere --except on our highways! For
example, Baron Nordenskiold remarked: (176)
In the first place I must call attention to the extreme
rarity of the occurrence of the remains of animals which have recently
died....
During my nine expeditions in the Arctic regions, where
animal life during summer is exceedingly abundant, I can recall very few
occasions upon which I have found remains of vertebrate animals which could be
proved to have died a natural death. Near hunting grounds there are to be
seen, often enough, the remains of reindeer, seals, foxes, or bears that have
died from gunshot wounds, but no naturally dead polar bear, seals, walrus,
white whale, fox, goose, auk, lemming or other vertebrates. The polar bear and
the reindeer are found there in hundreds: the seal, walrus, and white whale in
thousands: and birds in millions. These animals must die a natural death in
untold numbers. What becomes of their bodies? Of this we have for the present
no idea....
The only conclusion that one can draw from this is that
the death of these hundreds of thousands of large animals was unnatural, and
virtually simultaneous. How do we know it was simultaneous? Because, as we shall
see, similar vast cemeteries are found elsewhere, in which the predators and the
preyed upon died together, and there is no evidence of the bones of any of the
animals having been gnawed. The only difference between these animal cemeteries
in other parts of the world and those in Siberia is that the former were not
preserved by refrigeration, and therefore appear rather as vast assemblages of
bones. (177) In the Harvard Museum a slab six feet by ten feet contains bones so
thickly packed and in such confusion that there is every evidence of violence in
their compaction. In the Colorado Museum of Natural History a similar geological
exhibit is to be seen, taken from an animal cemetery at Agate Springs, in which
it is estimated that the bones of about 9000 complete animals are buried in one
hill. One section of such a bone cemetery is shown in Fig.2.

animal cemetery taken from a quarry at Agate Springs, Nebraska, and now
exhibited in the Denver Museum of Natural History. It contains bones of
thousands of animals, extending over a wide area. Photo used courtesy of the
Denver Museum of Natural History.
Howorth had this to say about these animal cemeteries:
(178)
The most obvious cause we can appeal to as occasionally
producing mortality on a wide scale among animals is a murrain or pestilence,
but what murrain or pestilence is so completely unbiased in its actions as to
sweep away all forms of terrestrial life, even the very carriers of it--the
rodents-- including the fowls of the air, the beasts of the field, elephants,
tigers, rhinoceroses, frogs, mice, bison and snakes, landsnails, and every
conceivable form of life, and this not in one corner only but, as far as we
know, over the whole of the two great continents irrespective of latitude or
longitude.
The fact of the bones occurring in great caches or
deposits in which various species are mixed pell-mell is very
important, and it is a fact undenied by geologists that whenever we find such
a locality in which animals have suffered together in a violent and
instantaneous destruction, the bones are invariably mixed and, as it were,
"deposited" in a manner which could hardly be explained otherwise than by
postulating the action of great tidal waves carrying fishes and all before
them, depositing them far inland with no respect to
order.
Howorth continued later:
If animals die occasionally (in large numbers) from
natural causes, different species do not come together to die, nor does the
lion come to take his last sleep with the lamb! The fact of finding masses of
animal remains.of mixed species all showing the same state of preservation,
not only points to a more or less contemporary death, but is quite fatal to
the theory that they ended their days peacefully and by purely natural
means.
If they had been exposed to the air, and to the severe
transition between mid-winter and mid-summer, which characterizes Arctic
latitudes, the mammoths would have decayed rapidly. But their state of
preservation proves that they were covered over and protected ever
since.
This renowned but neglected authority concluded:
(179)
It is almost certain in my opinion that a very great
cataclysm or catastrophe occurred by which the mammoth and his companions were
overwhelmed over a very large part of the earth's surface. And that the same
catastrophe was accompanied by a very great and sudden change of climate in
Siberia, by which the animals which had previously lived in fairly temperate
conditions were frozen . . . and were never once thawed until the day of their
discovery. No other theory will explain the perfect preservation of these
great elephants.
From the Antarctic also there is evidence, according to
geologists of the Byrd Expedition, (180) of similarly different climatic
conditions. Great coal fields, evidence of luxuriant growth, were discovered at
the head of Thorne Glacier in the Queen Maude Range within 200 miles of the
South Pole. Such conditions so near to that frightful wilderness of ice and
snow, which is so much more terrible than the North Pole in its coldness and
barrenness, is remarkable witness of a previous world which must have been a
very different one. So numerous are the fossils there that the explorers
actually had difficulty making a selection. Today life in these regions is
conspicuously absent.
Evan Hopkins remarked that the fossil plants of
north Greenland proved that the land has been favored with a climate at least
30º F, warmer than at present. (181) He pointed out also that among the animals
entombed in the deposits in Siberia besides the mammoths are bears, hippos,
hyena, lions, tigers, and others which can only live and flourish in or near the
tropics. Moreover, the fossil forest at Atanekerdluk at a latitude of 70º is
indicative of a temperature of at least 30º F, higher than is now found at that
parallel. Similar conditions are likely to be found now at the 48º parallel, a
fact which shows a shift of climate with respect to the equator.
What has been said of land animals is equally true of
fishes and even of plants. Some years ago Philip Le Riche presented a paper
before the Victoria Institute in London in which he made this statement:
(182)
It can easily be shown that many of the strata contain
the fossil remains of fish which have been suddenly interred before
putrefaction had acted upon their fleshy bodies, for their bodies are
preserved as they were during life. And this remarkable state of preservation
of fish life is also found in the flora. For plants as fine as maidenhair
ferns are found embedded in the strata with even their venules intact, showing
that they must have been buried very shortly after their deposition in the
sediment, otherwise they would have become converted into leaf mold and
indistinguishable, whereas a botanist can place the fossil plant in its proper
order of plant life.
The suddenness of this destruction is further strikingly
borne out by the fossil cuttlefish of Lyme Regis that were killed and entombed
with such inconceivable rapidity that they still retain the dark fluid with
which their ink bags are filled when alive. (183) But these animals when
disturbed release this protective device within a matter of seconds. Speaking of
fish, Howorth even recorded a whale which was found entombed with the elephants,
a discovery which Pallas confirmed--mentioning also buffalo in situ with the
heads of large fishes.
In spite of the fact that many of these authorities would
now be considered quite out of date, so that their interpretations would almost
certainly be rejected, the evidence itself remains undeniable; and it is
difficult to explain it satisfactorily in any other way. In concluding this
brief survey, and referring this time to accumulations of bones which were
washed pell-mell into fissures and clefts in the rocks, one can reflect upon the
words of the venerable Joseph Prestwich, affectionately styled the Father of the
Geological Society. After speaking of such animal cemeteries and pointing out
how the bones of carnivores are mixed indiscriminately with those of their
natural prey, the bodies seeming to have been torn apart with violence, he
summed the situation up by saying: (184)
These bones cannot be of animals which fell into these
fissures (where they are found in such profusion), for no skeleton is
complete. They cannot have been brought by beasts of prey, for none are
gnawed. They were not brought by streams (i.e., spring floods), for none are
rolled. The bones could not have laid exposed for long, for none are
weathered. They were not covered up normally, for they were broken by the
violence of their deposition together with the associated rocks....
The formation of these fissure deposits in so many
places . . . seems to confirm the belief that the rubble drift itself did not
owe its origin to normal causes, but to something catastrophic in the nature
of earth movements.
Such, then, is the kind of evidence which is to be found
all over the world of the sudden death of an enormous number of animals of very
recent and modern times. Some of these creatures died in latitudes that were
almost at once plunged into an Ice Age which preserved them by freezing. Some of
them died in more temperate zones and were accumulated by the action of torrents
of water sweeping hither and yon as the earth reeled, before the waters had been
sufficiently gathered together in one place to expose the dry land. And,
finally, some were accumulated and rammed together forcibly and indiscriminately
into clefts in the rocks which served to sieve them out of the draining
waters.
The suddenness of the event is everywhere attested, in
the Arctic by the extraordinary state of preservation of mammoths and other
creatures, and in the more temperate zones by the very fact that predators and
preyed upon came to a sudden end together. Even within the waters, the movements
of silt and water-washed materials were sometimes so sudden and overwhelming
that fishes were trapped before they had the few seconds necessary to react in a
characteristic defensive way. Some bivalved forms, in fact, were overwhelmed so
rapidly that they did not have time to close.
Furthermore, we may conclude, I think, that the
catastrophe which was worldwide profoundly affected world climate. There are
some who believe that the Ice Age is bound up with the sudden subsidence of the
waters . They argue that the effect of this subsidence was greatly to increase
the exposed land area. I am not competent to assess the mechanics of this
hypothesis, but there is little doubt that what has been observed was related to
the coming of the great cold which brought ice down over half of the northern
hemisphere and introduced the world to an Ice Age from which we really have not
yet altogether recovered. We may say that the ice caps have merely retreated far
enough to allow most of us to ignore them. And the event was recent indeed. The
present is, geologically speaking, the end of the Pleistocene. It is as Shull
has observed: (185)
At few points in geological history has there been
extermination comparable to that of mammals in the time just preceding the
recent. In part this may be due to repeated glaciation, but most of it is
unexplained. Only the tropical regions, notably Africa, escaped this great
diminution of mammals, and the Pleistocene mammals of that continent were
essentially the same as today.
A study of the rocks indicates that the same may be said
largely of Australia. The pattern of fossil marsupials has continued on in that
continent and is still with us. It is probably true, as Baker pointed out, that
not a few species of animals--indeed, large areas of living things--might very
well have survived the catastrophe. But those which perished irretrievably as
species had to be recreated. (186) Those species which had not perished
altogether began once more to multiply. Possibly this is why in Genesis 1 God
said in some cases, "Let the earth bring forth. . . ," while in other cases
Scripture says, "So God created. . . ," etc. Not everything had to be recreated;
and as for plant life, the earth perhaps did indeed bring forth seed which was
in itself--in the earth (Gen. 1:11).
Perhaps the tilting of the earth' s axis by as much as
40º or more at the time of the last great convulsion of nature may have been
partially responsible for the fact that in the New World, for example, the great
ice sheet reached down over New York State. Possibly we shall yet discover what
upset the earth's equilibrium at the time to cause this tilt. When--and if--this
axis of rotation becomes completely vertical again, the ice caps will presumably
disappear entirely and the whole earth could enjoy a temperate climate. The
recovery at present is only partial (23º), so that although the ice retreats
annually, we still have polar caps with us. If we assume that the axis of
rotation of the world that then was, was normal to the earth's plane of rotation
around the sun, then that world would have enjoyed a much more temperate climate
over its whole surface. This could have important theoretical implications, for
as H. Hamshaw Thomas of Cambridge, in a letter to Nature, pointed out:
(187)
The possibility that changes have occurred during the
past in the position of the earth's axis of rotation. . . is of great interest
to all students of fossil plants.
It has long been clear that the geological evidence of
former vegetation shows that the lands around the Arctic Sea bore an ample
covering of plants during a long period, probably from Devonian to Tertiary
times. This vegetation included many large trees and was very different from
the scanty flora of these regions living today.
And so the Old World was suddenly brought to an end just
when it had seemed ready to receive man as its paramount chief. But God had
formed it and given it its appointments and established its natural order; and
He had not created all this in vain (Isa. 45:18). He had intended it in the
first place as a habitation for man, and although His intention had been
forestalled by some counteragency, that intention stood firm: and so the process
of reconstitution was once again undertaken by the Lord to put everything ready
for the introduction of man, for whom it had all been planned.
Thus man finds himself in a world in which there are
strange contradictions. Everywhere to the eye of faith there is evidence of plan
and purpose--such evidence, in fact, that even the unbelieving find it hard not
to recognize it. At the same time, equally ubiquitous, is the evidence of
catastrophe and judgment, as though some contrary planner had been at work
seeking to thwart the Creator's design, and more particularly and more
dramatically just when man's coming was drawing near.
Perhaps it is time to reassess the geological evidence in
the light of these two opposing forces, one for good and one for
evil.
