 EVIDENCE FOR EVOLUTION 



THE Theory of Evolution has given occasion for a more searching 

 discussion of the problem concerning Man s Place in Nature. 

 Nature must be taken as a whole. Man is the most conspicuous 

 figure in an organised system of things. Nature designates 

 this system. Man s place can be ascertained only under full 

 acknowledgment of the laws of evolution. The presence of life 

 on the earth is presupposed as an unexplained occurrence- 

 Evolution cannot be a complete Natural History. Evolution 

 is the unfolding of life under the action of Environment, 

 The interaction of life and environment has led to results 

 endless and varied. These have generally, though not uni 

 formly, been progressive. Human history must be traced 

 within the world-history. Darwin s accumulated results apply 

 much more to animal life than to human. Limits of food 

 supply. Adaptation of organism to its conditions. Conflict, 

 the inevitable condition of progress. Large sacrifice of life, a 

 uniform consequence. Evolution illustrates laws of organic 

 growth, persistence of species, and modifications of species. 

 Artificial selection, under domestication, illustrates the laws of 

 Nature. The accepted inductions of modern science call for 

 extended interpretation of Nature. An enlarged view of Cosmic 

 Causes is a pressing want. The laws of Heredity. The 

 problems of Embryology. Man s place, the most intricate of 

 problems. Its solution must largely affect our theory of 

 Nature. In developing his theory, Darwin could not have 

 done otherwise than give the chief place to animal life. 

 Disadvantages of this, when proceeding to the problem of Man s
