A simple and concise discussion for the educated layman of 
present-day scientific criticism of the Darwinian selection 
theories, together with concise accounts of the other more in- 
portant proposed auxiliary and alternative theories of species- 
forming. With special notes and exact references to original 
sources and to the author’s own observations and experiments. 
“Its value cannot be overestimated. A book the student must have at 
hand at all times, and it takes the place of 4 whole library. No other 
writer has attempted to gather together the scattered literature of this 
vast subject, and none has subjected this literature to such uniformly 
trenchant and uniformly kindly criticism. Pledged to no theory of his 
own, and an investigator of the first rank, and master of a clear and force- 
ful literary style, Professor Kellogg is especially well fitted to do justice 
to the many phases of present-day Darwinism.’’—Davip Starr JORDAN 
in The Dial. 
‘*May be unhesitatingly recommended to the student of biology as well 
as to the non-professional or even non-biological reader of intelligence 
gives a full, concise, fair and very readable exposition of the present status 
of evolution.’’—The Independent. 
“Can write in English as brightly and as clearly as the old-time French- 
men . a book that the ordinary reader can read with thorough enjoy- 
ment and understanding and that the specialist can turn to with profit 
as well in his text he explains the controversy so that the plain man 
may under stand it, while in the notes he adduces the evidence that the 
specialist requires. The whole matter is thoroughly digested and put in 
an absolutely intelligible manner. . a brilliant book that deserves gen- 
eral attention.”’"—New York Sun. 
“The balance-sheet of Darwinism is struck in this work the attack 
and the defense of Darwinism, well summarized . the value of this 
book lies in its summing up of the Darwinian doctrines as they have been 
modified or verified down to date.’’—Literary Digest.
