g6 READINGS IN EVOLUTION, GENETICS, AND EUGENICS 



Man is hardly as yet subject to Malthus' law, for while he is 

 increasing more rapidly than any other animal, owing largely to the 

 care of the young which makes the expectation of life of the new-born 

 relatively very high, his migratory ability, but above all his intelli- 

 gence, save him from the application of the law. A single new dis- 

 covery such as that of electricity may increase his food supply and 

 other life necessities several fold. His future evolution, in so far as 

 it is progressive, will be mental and spiritual rather than physical, and 

 as such will be the .logical conclusion of the marvelous results of 

 organic evolution.
