 is, indeed, suggested by Darwin himself, who 

 writes : " It is quite possible that as the one 

 sex gradually acquired the accessory organs 

 proper to it, some of the successive steps or 

 modifications were transmitted to the opposite 

 sex."* 



Another secondary sexual character in man 

 is the beard. Darwin accounts for its existence 

 in a rudimentary condition, and its occasional 

 development in women, by supposing that the 

 early progenitors of man were bearded in both 

 sexes.f This supposition, and the somewhat

 animal kingdom. The development of hair on
