The Russo-French physiologist, M. Elie DeCyon, for many years professor in the Faculty of Sciences and in the Academic Medico-chirurgicale at the University of Petrograd, has lately published a book of essays in which he says that the theory of evolution, especially in its relation to the ancestry of man, is a "pure assumption." He quotes Prof. Fraas, who devoted his long life to the study of fossil animals: "The idea that mankind has descended from any Simian (ape) species whatsoever, is certainly the most foolish ever put forth by a man writing on the history of man. It should be handed down to posterity in a new edition of the Memorial of Human Follies. No proof of this baroque theory can ever be given from discovered fossils." And to quote from another address by Virchow, delivered at Vienna: "I have never found a single ape skull which approaches at all the human one. Between men and apes there exists a line of sharp demarcation." One of the most recent authoritative publications by a German anthropologist urges that "the apes are to be regarded as degenerate branches of the pre-human stock." This means, in a word, that man is not descended from the ape, but the ape from man. This is almost what may be called _reductio ad absurdum,_ and yet it is one of the latest pronouncements of scientific thought (Editorial in _"New York Herald,"_ December 30, 1916). To the same effect are the words of Professor Wood-Jones, Professor of Anatomy in the University of London, England, who recently pointed out that so far from man having descended from anthropoid apes, it would be more accurate to say that these have been descended from man. This was claimed not only by reason of the best anatomical research, but to be "deducible from the whole trend of geological and anthropological discovery." On this account Professor Wood-Jones appealed for "an entire reconsideration of the post-Darwinian conceptions of man's comparatively recent emergence from the brute kingdom." (Quoted by W. H. Griffith Thomas in _"What about Evolution?"_ p. 10.)
