What Was the Cause?
Darwin, Wallace and other scientists of that day put forth theories to explain this worldwide
decimation of animal life. But no theory was accepted by all scientists. ALL the theories had weak
points; no one idea accounted for all the phenomena.
Especially puzzling were the fossils of extinct animals in the deep Alaskan muck beds. Equally
perplexing was the Siberian record. The evidence at face value told a story of violent catastrophe.
The record demanded area-wide, continent-wide, indeed WORLDWIDE - and simultaneous ca-
tastrophe.
This baffled the original workers; it still baffles scientists today. Any ideas put forth today are
generally rehashes of theories thought of long ago.
"The mysteries of extinction are so many and so baffling," wrote two archaeologists, "that it is
small wonder no book in English has been written on the subject. Since 1906, when Henry Fairfield
Osborn summed the matter up in his paper of fifty-odd pages, 'The Causes of Extinction of
Mammalia," Eiseley [famed anthropologist] credits only two theories with contributing anything
new to the discussion" (Kenneth Macgowan and Joseph Hester, Early Man in the New World, New
York: Doubleday, 1962, p.202).
Were Ice Ages Responsible?
Earlier workers postulated that Ice Ages were responsible for the mass killings. Not long ago, many
paleontologists became rather cool to this idea. And for good reasons. The death-by-refrigeration
idea simply didn't hold water. It was put into deep freeze storage for the following reasons, neatly
summed up in a book already quoted.
"Horses, camels, sloths, antelopes, all found slim pickings in their former habitat. But what was to
prevent these animals from simply following the retreating ice to find just the type of vegetation
and just the climate they desired? If Newport is cold in the winter, go to Florida. If Washington
becomes hot in the summer, go to Maine" (Frank C. Hibben, The Lost Americans, New York:
Apollo Editions, 1961, p. 176).
This was a good question. And it couldn't be answered.
A typical problem was the glyptodont. Paleontologists regarded him as strictly tropical in
adaptation. But here was the rub. Glaciation could not account for his extinction, unless:
"Unless one is willing to postulate freezing temperatures across the equator, such an explanation
clearly begs the question of their extinction in tropical America" (P. S. Martin and H. E. Wright,
Jr., editors, Pleistocene Extinction, "Bestiary for Pleistocene Biologists," by P. S. Martin and J. E.
Guilday, New Haven: Yale, 1967, p.23).
Giant tortoises, victims of this same mammal destruction, were found throughout the warmer parts
of the world. No paleoclimatologist was prepared to say that in glacial times freezing temperatures
extended through the Caribbean.
It is no wonder paleontologists put the Ice Age theory of extinction into cold storage. It simply
could not explain catastrophe in the tropics.
Equally perplexing was the mysterious extinction of horses in North America. About a decade ago,
eminent paleontologist G. G. Simpson was discussing this problem. It was a real head-scratcher.
When horses were reintroduced into the western hemisphere a few hundred years ago by the
(Pg. 5)
Spaniards, they increased marvelously. If the present climate and terrain is so favorable, what
caused their total extinction in the time just after the Ice Age?
To George Gaylord Simpson, it was one of the most mysterious episodes of animal history."
Wiped Off the Face of the Earth
What signed the horses' death warrant - killing them in droves? For Dr. Simpson, there was no
answer:
"There has been no lack of speculation and a dozen possible explanations have been suggested, but
all of these lack evidence and none is really satisfactory."
After explaining why he, in particular, rejected the Ice Age as the Grim Reaper of horses, Simpson
dejectedly summarized by saying:
"This seems at present one of the situations in which we must be humble and honest and admit that
we simply do not know the answer."
"It must be remembered too that extinction of the horses in the New World is only part of a larger
problem. Many other animals became extinct here at about the same time" (George Gaylord
Simpson, Horses, New York: Doubleday, 1961, pp. 198, 200).
Why did the horse cash in - so violently and quickly? Why did the candle go out on so
many hardy species of mammal life around the world? What caused the mass destruction in
Alaska? How did mammal genocide across the vast stretches of Siberia occur? What caused the last
gasp, the death rattle of land-living creatures in every continent the world over?
Was Man the Killer?
As paleontologists discussed the problem, a new gleam came to many an eye. They saw that the
remains of man - camp fires, burnt bones, arrow-heads - are sometimes associated with animal
remains.
The more they thought about it, the greater became their excitement. "Could man be responsible for
the decimation and extinction of mammal life?" they asked.
It was an intriguing idea.
Extinction occurred almost exclusively on land. It sometimes occurred with definite evidence of
the presence of man. Further, the explanation seemed to be the ONLY ONE left.
Paleontologists published a book, Pleistocene Extinctions, The Search for a Cause, in 1967. The
book was based largely on papers read during the Proceedings of the VII Congress of the In-
ternational Association for Quaternary Research.
From the reports, it was quite evident that the new "overkill" idea was too impotent to be the
answer to the mammal massacre. Although a number of paleontologists accepted the idea, they had
to acknowledge the weakness of the theory
The following statement shows why any such human "overkill" idea is in-adequate:
"We may speculate but we cannot determine how moose, elk, and caribou managed to survive
while horse, ground sloth, and mastodon did not."
"One must acknowledge that within historic time the Bushmen and other primitive hunters at a
Paleolithic level of technology have not exterminated their game resources, certainly not in any
way comparable to the devastation of the late-Pleistocene."
(Pg. 6)
These and other VALID OBJECTIONS to the hypothesis of overkill remain (P. S. Martin,
"Prehistoric Overkill," in Pleistocene Extinctions, The Search for a Cause, P. S. Martin and H. E.
Wright, Jr., editors, New Haven: Yale, 1967, p. 115).
Further, anthropologist Arthur Jelinek in his article "Man's Role in Extinction of Pleistocene
Faunas" for the above-mentioned book, had this to say:
"Throughout the New World one major puzzle exists with regard to linking man with the
extinction. This is the absence of direct evidence of human activity associated with the remains of
extinct animals" (ibid., p. 198).
More staggering were the masses of bone in Siberia and Alaska. Surely, these could not be
explained as the "overkill" effects of man.
The Problem of Siberia
Russian scientist N. K. Vereshchagin was blunt. He simply disagreed that man could be responsible
for the massive piles of animal bones in Siberia.
"The accumulations of mammoth bones and carcasses of mammoth, rhinoceros, and bison found
in frozen ground in Idigirka, Kolyma, and Novosibirsk islands bear no trace of hunting or activity
of primitive man" (ibid., "Primitive Hunters and Pleistocene Extinction in the Soviet Union" p.
338).
That man hunted animals is not in dispute. That he may have "overkilled" in local areas is, of
course, likely. Some fossils would bear this out.
But to accuse man as solely responsible for killing ALL the animals whose fossils are found round
the world is impossible. Even where animal fossils and evidence of man are found together, man is
sometimes one of the fossils! The Death Reaper claimed both man and beast.
A Worldwide Catastrophe
The evidence - globe-wide evidence - seems to demand a WORLDWIDE paroxysm.
"Either some UNIQUE NATURAL CATASTROPHE must have precipitated extinction or else
natural environmental changes had nothing to do with the event" (P. S. Martin, "Prehistoric
Overkill," in Pleistocene Extinctions, P.S. Martin and H. E. Wright, Jr., editors, New Haven: Yale
University Press, 1967, p. 86).
There it is in a nutshell. The type of catastrophe demanded by the evidence would sabotage the
uniformitarian idea that the "present is the key to the past."
In the preface of the same book, P.S. Martin asked:
"If climatic change was responsible, then it must have been a change of a magnitude not known
previously. Are meteorologists prepared to recognize the possibility of a climatic shock wave of
UNPRECEDENTED DIMENSION?"
In fact, "unprecedented" is a weak word. Better phrased is Hibben's explanation:
"Throughout the Alaskan mucks," said this startled scientist, "there is evidence of atmospheric
disturbances of unparalleled violence. Mammoth and bison alike were torn and twisted as though
by a cosmic hand in godly rage" (Frank C. Hibben, The Lost Americans, New York: Apollo
Editions, 1961, p.177).
