 SEXUAL SELECTION IN RELATION TO MAN. 



CHAPTER XIX. 



SECONDARY SEXUAL CHARACTERS OF MAN. 



Differences between man and woman Causes of such differences 

 and of certain characters common to both sexes Law of battle 

 Differences in mental powers and voice On the influence of 

 beauty in determinging the marriages of mankind Attention 

 paid by savages to ornaments Their ideas of beauty in woman 

 The tendency to exaggerate each natural peculiarity. 



With mankind the differences between the sexes are 

 greater than in most of the Quadrumana, but not so great 

 as in some, for instance, the mandrill. Man on an average 

 is considerably taller, heavier and stronger than woman, 

 with squarer shoulders and more plainly pronounced mus- 

 cles. Owing to the relation which exists between muscular 

 development and the projection of the brows,* the super- 

 ciliary ridge is generally more marked in man than in 

 woman. His body, and more especially his face, is more 

 hairy, and his voice has a different and more powerful tone. 

 In certain races the women are said to differ slightly in tint 

 from the men. For instance, Schweinfurth, in speaking of 

 a negress belonging to the Monbuttoos, who inhabit the 

 interior of Africa a few degrees north of the equator, 

 says: ^^Like all her race, she had a skin several shades 

 lighter than her husband's, being something of tUe color of 

 half -roasted coffee." f -^s the women labor iu the fields 

 and are quite unclothed, it is not likely that they differ in 

 color from the men owing to less exposurt to the weather.
