SELECTION ON MAN. 329 



have remained generically, or even specifically, the 

 same, while his head and brain alone will have un-

 structure of his body, there is the closest anatomical 

 resemblance to the anthropoid apes, " every tooth, every

 nation of the difference between Homo and Pithecus 

 the anatomist's difficulty." The present theory fully 

 recognises and accounts for these facts ; and we may 

 perhaps claim as corroborative of its truth, that it 

 neither requires us to depreciate the intellectual chasm 

 which separates man from the apes, nor refuses full 

 recognition of the striking resemblances to them, which 

 exist in other parts of his structure. 



Conclusion. 



In concluding this brief sketch of a great subject, 

 I would point out its bearing upon the future of the 

 human race. If my conclusions are just, it must in- 

 evitably follow that the higher the more intellectual 

 and moral must displace the lower and more de- 

 graded races ; and the power of " natural selection," 

 still acting on his mental organization, must ever lead 

 to the more perfect adaptation of man's higher facul-
