SEXUAL SELECTION IN BELATIOK WO MAN 717 



color of half -roasted coffee." ' As the vvromen labor in the 

 fields and are quite unclothed, it is not likely that they 

 differ in color from the men owing to less exposure to the 

 weather. European women are perhaps the brighter col- 

 ored of the two sexes, as may be seen when both have 

 been equally exposed. 



X Man is more courageous, pugnacious, and energetic than 



/ woman, and has a more inventive genius. His brain is ab- 



' solutely larger, but whether or not proportionately to hia 



\ larger body, has not, I believe, been fully ascertained. In 



woman the face is rounder; the jaws and the base of the 



skull smaller; the outlines of the body rounder, in parts 



more prominent; and her^ pelvis is broader than in man;* 



but this latter character may perhaps be considered rather 



as a primary than a secondary sexual character. She comes 



to maturity at an earlier age than man. 



As with animals of all classes, so with man, the distinc- 

 tive characters of the male sex are not fully developed until 

 he is nearly mature; and if emasculated they never appear. 

 The beard, for instance, is a secondary sexual character, and 

 I male children are beardless, though at an early age they c 

 I have abundant hair on the head. It is probably due to ' 

 the rather late appearance in life of the successive varia- 

 tions whereby man has acquired his masculine characters, 

 that they are transmitted to the male sex alone. Male and 

 female children resemble each other closely, like the young 

 of so many other animals in which the adult sexes differ 

 widely; they likewise resemble the mature female much 

 more closely than the mature male. The female, however, 

 ultimately assumes certain distinctive characters, and in the 



(formation of her skull is said to be intermediate between 

 the child and the man.* Again, as the young of closely
