THEORY OF EVOLUTION 193 



might be claimed that the point is not whether 

 we can exphiin how creation takes place, but 

 whether we can get verifiable evidence that. such 

 a kind of thing happens. This possibility is 

 disposed of by the fact that there is no evidence 

 that selection determines the direction in whicli 

 variation occurs. 



Second, if you mean by a creative process 

 that by })icking out a certain kind of individual 

 and multiplying its numbers a better chance is 

 furnished that a certain end result will be ob- 

 tained, such a process may be said to be crea- 

 tive. This is, I think, the proper use of the 

 term creative in a mechanistic sense. 



Conclusions 



In reviewing the evidence relating to selec- 

 tion I have tried to handle the problem as ob- 

 jectively as I could. 



The evidence shows clearly that the charac- 

 ters of wild animals and plants, as well as those 

 of domesticated races, are inherited l)oth in the 

 wild and in the domesticated forms according 

 to ^Mendel's Law.
