THE DARWINIAN THEORY 



entitled Darwinism To-day, says, page 

 90: " Men using, or rather testing, these 

 theories every day in their work in field 

 and laboratory, find selection insufficient 

 to explain the conditions that their ob- 

 servation and experiments reveal to them. 

 These men are students in all the lines of 

 biological work, whether zoologists, bot- 

 anists, paleontologists or animal and plant 

 breeders. From all these lines of work 

 come increasing complaints ; selection can- 

 not explain for me what I see to exist. 

 From some the cry is more bitter; selec- 

 tion is a delusion and false guide. I re- 

 ject it utterly. For me [Kellogg] I re- 

 peat this is an objection of much signifi- 

 cance and importance that the biological 

 experimentalists, the students of variation 

 and heredity, of life mechanics, are find- 

 ing the rigid theory of selection's control 

 of all processes and phenomena a rack on 

 which they will no longer be bound."
