28 WHAT EVOLUTION IS 



pected. The human arm, the foreleg 

 of a quadruped, the wing of a bird, and 

 the flipper of a whale have a common 

 plan of organization because these 

 animals have had a common ancestry. 

 Thus the science of comparative an- 

 atomy yields results that support 

 most completely the evolutionary 

 idea, and that give no ground for the 

 assumption of special creation. It is 

 a remarkable fact that Cuvier, who, 

 as already observed, was a strong 

 anti-evolutionist, should have been 

 instrumental in founding and in 

 partly developing a school that in the 

 end yielded such important evidence 

 in favor of descent with modification.
