Sexual Dimorphism in the Animal Kingdom; a Theory of the Evolution of Secondary Sexual Characters

Abstract

HOWEVER much readers of this work may dissent from the views of the author, there can be no doubt that the volume is worthy of the most careful perusal. For the first time since the publication of Darwin's theory of sexual selection we have been provided with a bold and intelligible attempt at explaining secondary sexual characters on Lamarckian principles, and although many of us may arrive at the conclusion that Mr. Cunningham has not succeeded in establishing his case, it will be generally admitted that he has discussed the problem, on the whole, in a more or less scientific spirit, and has supported his arguments by a body of well-considered and, in many cases, original observations, which make his book exceptionally valuable as a storehouse of facts.

Sexual Dimorphism in the Animal Kingdom; a Theory of the Evolution of Secondary Sexual Characters.
