A simple and concise discussion for the educated lajnnan of 

 present-day scientific criticism of the Darwinian selection 

 theories, together with concise accounts of the other nK)r(' im- 

 portant proposed auxiliary and alternative theories of sjx'cies- 

 forming. With special notes and exact references to original 

 sources and to the author's own ob.servations and experiments. 



"Its value cannot be overestimated. A book the student must have at 

 hand at all times, and it take.s the place of a whole library. No other 

 writer has attempted to gather together the scattered literature of thi.'^ 

 vast subject, and none has subjected this literature to such unifonnly 

 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." — D.wid St.\kk Johuan 

 in The Dial. 



"May be unhe.sitatingly 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 tlie 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 i>laiii man 

 may under .stand it, while in the notes lie adduces the evidence that the 

 specialist requires. The whole matter is thoroughly digeste<l and put in 

 an absolutely intelligible manner ... a brilliant b(jok that deserves gen- 

 eral attention." — Sew York Sun. 



"The balance-.sheet of Darwinism is struck in this work . . . the attack 

 and the defen.se of Darwinism, well summarized ... the value of this 

 book lies in its summing up of the Darwinian iloctrines as tliey have been 

 modified or verified down to date." — Literary Diiiest.
