from the domain of
science those who will not be dragged into this mire of mere assertion,
then it is time to protest."

Dr. J. B. Warren, of the University of California, more recently said:
"If the theory of evolution be true, during the many thousands of years
covered in whole or in part by present human knowledge, there would
certainly be known at least a few instances, or at least one instance,
of the evolution of one species from another. No such instance is known.
Abstract arguments sound learned and appear imposing, so that many are
deceived by them. But in this matter we remove the question from the
abstract to the concrete. We are told that facts warrant the
evolutionary theory. But do they? Where is one single fact?"

The hypothesis assumes that through environment, certain varieties of
species (both of plants and animals) arose, and that the varieties best
fitted, through their habits, structure, or color, to maintain
themselves in the struggle for existence, survived the species less
favorably endowed, and hence persisted. (We have quoted in our initial
chapter the classical illustration of the dipper-birds from Wallace's
_"Darwinism."_)

Now, as a matter of fact, we cannot prove that a single species has
changed. These are the words of Darwin himself, quoted from _"Life and
Letters,"_ Vol. III, p. 25: "There are two or three million of species
on earth, sufficient field, one might think, for observation. But it
must be said to-day that in spite of all the efforts of trained
observers, not one change of a species into another is on record." Dr.
N. S. Shaler, Professor of Geology in Harvard, asserts that "it has not
been proved that a single species has been established solely or even
mainly by the operation of Natural Selection." Professor Fleischmann, of
Erlangen, has gone so far as to say that "the Darwinian theory of
descent has, in the realms of nature, not a single fact to confirm it."
Dr. Ethridge of the British Museum says: "In all this great museum there
is not a particle of evidence of transmutation of species. Nine-tenths
of the talk of evolutionists is sheer nonsense, not founded on
observation and wholly unsupported by facts." Prof. Owen declares that
"no instance of change of one species into another has ever been
recorded by man." Dr. Martin, Sanitaetsrat, of Germany, who has
conducted some highly technical experiments in the blood reactions of
various animals and man, on which he bases hi
