WHAT I PHYSICAL LIFE 



rocks, from that date to this period is but 

 a speck in infinite time. But granting 

 this restricted period, numbers of biol- 

 ogists maintain that the supposed powers 

 of environment are more destructive than 

 selective, or, as Dr. Morier says, the proper 

 term for them is natural Extermination 

 rather than natural Selection. Among 

 the countless copepods which a whale sifts 

 for food out of sea water, what difference 

 does it make if some of the copepods had 

 become more developed than others or not ; 

 they all would have to go together down 

 the whale's throat. 



Among American biologists the oppo- 

 nents of the theory of natural selection are 

 no less numerous. As Professor V. L. 

 Kellogg* of the Leland Stanford Uni- 

 versity of California, in his elaborate work 



* Professor Kellogg's book affords one of the best re- 

 views that is published on this subject, and contains im- 

 partially the statements of both those who favor and who 

 oppose the Darwinian Theory among biologists.
