12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 85 



special assortment of these characteristics makes a species better, 

 more efficient, or more at ease in the world than one that has another 

 assortment. So also with man. 



The similarities that I have shown to exist between some hair 

 characteristics of man and those of particular monkeys and apes must 

 not be supposed to indicate any special relationship between man and 

 these other primates. When superficial features of this kind are 

 common to a whole group they will often appear in almost identical 

 form in two animals whose relationship is shown by their anatomical 

 structure to be remote.
