382 SEXUAL SELECTION : MAN. Part IL 



through sexual selection ; but this view is supported by 

 various analosfies, and we know that nesfroes admire 

 their own blackness. With mammals, wlien the sexes 

 differ in colour, the male is often black or much darker 

 than the female ; and it depends merely on the form of 

 inheritance whether this or any other tint shall be trans- 

 mitted to both sexes or to one alone. The resemblance 

 of Pithecia satanas with his jet black skin, white rolling 

 eyeballs, and hair parted on the top of the head, to a 

 negro in miniature, is almost ludicrous. 



The colour of the face differs much more widely in 

 the various kinds of monkeys than it does in the races 

 of man ; and we have good reason to believe that 

 the red, blue, orange, almost white and black tints of 

 their skin, even when common to both sexes, and the 

 brisfht colours of their fur, as well as the ornamental 

 tufts of hair about the head, have all been acquired 

 througli sexual selection. As the newly-born infants of 

 the most distinct races do not differ nearly as much in 

 colour as do the adults, although their bodies are com- 

 pletely destitute of hair, we have some slight indication 

 that the tints of the different races were acquired sub- 

 sequently to the removal of the hair, which, as before 

 stated, must have occurred at a very early period. 



Summary. — We may conclude that the greater size, 

 strength, courage, pugnacity, and even energy of man, 

 in comparison with the same qualities in woman, were 

 acquired during primeval times, and have subsequently 

 been augmented, chiefly through the contests of rival 

 males for the possession of the females. The greater 

 intellectual vigour and power of invention in man is 

 probably due to natural selection combined with the 

 inherited effects of habit, for the most able men will 

 have succeeded best in defending and providing for
