THE DARWINIAN THEORY 



and varied that by an unavoidable neces- 

 sity its cultivation can be carried on only 

 by great numbers of hard-working spe- 

 cialists, such as zoologists, naturalists, 

 botanists, entomologists, embryologists, 

 paleontologists, anatomists, physiologists, 

 pathologists, physicians, etc., every one of 

 whom has something important to say 

 about the development and laws of life. 

 On any other highly complex subject ex- 

 pert opinion is most sensibly asked, but 

 in biology only such opinion is worth any- 

 thing. And it is but the simple truth to 

 say that at present the opinion of such ex- 

 perts in all the different fields of biological 

 research is preponderately adverse to the 

 claims of the Darwinian theory, and is 

 steadily growing more so. A few cita- 

 tions, out of many more which our limits 

 forbid our quoting, from the writings of 

 leading European and American biol- 

 ogists will suffice to make this plain.
