303 SEXUAL SELECTION: MAN. [Part D. 



size of his l^ody, in comparison with that of woman, has 

 not, I holieve, been fully ascertained. In woman the face 

 is rounder ; the jaws and the base of the skull smaller ; 

 the outlines of her 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 dis- 

 tinctive characters of the male sex are not fully developed 

 until he is nearly mature ; and if emasculated they never 

 ai)i>i'ar. The beard, for instance, is a secondary sexual 

 character, and male children are beardless, though at an 

 early age they have abundant hair on their heads. It is 

 probably due to the rather late appearance in life of the 

 successive variations, by which man 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 ; 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 interme- 

 diate between the child and the man.' Again, as the young 

 of closely-allied though distinct sjjecies do not differ nearly 

 80 much from each other as do the adults, so it is with 

 the children of the different races of man. Some have 

 even maintainiMl that race-differences cannot be detected 

 in the infantile skull. ^ In regard to color, the new-born

 been followed out with much care by Welcker.
