AS THE BIOLOGIST SEES IT 



way of social evolution, based on man's 

 social inheritance and the biologic factor 

 of mutual aid. If so, we have not to look 

 forward to future man as a physically 

 different man unless indeed he gives up 

 a little more of that original physical 

 equipment which enabled him to live 

 successfully in Glacial Time as "animal 

 among animals" but we have to see man 

 of the future as the possessor of an ever 

 more elaborate and higher development 

 of social inheritance, and more and more 

 capable, by virtue of this social inherit- 

 ance, of an inhibition of the vestigial brute 

 carry-overs in his biological inheritance. 

 That means, in ultimate analysis, that 

 future man can be consciously deter- 

 mined by man today, that human evolu- 

 tion has been turned over to human- 

 kind itself to direct. 



What an opportunity, but at the same 

 time what a responsibility! Poor star- 

 fishes and clams, poor ants and bees, and 

 all the other little animal brothers to man 

 whose fate and future are all in the laps
