^^~^^ ZOOGENESIS ^1^ 



known word results always in confusion. The term 

 evolution is commonly used to cover the entire devel- 

 opmental history of animals. But evolution con- 

 templates a gradual and continuous unfolding of ani- 

 mal life beginning with creatures consisting of a 

 single cell and ending with man. A better under- 

 standing of the subject will result if we recognize the 

 fact that this process includes three distinct but inter- 

 related phases, first, evolution properly so called; 

 second, mutations; and third, eogenesis. 



If we regard the complete history of the develop- 

 ment of animal life in this light we must, in order to 

 avoid confusion, use for it an entirely new term. We 

 may call it %po genes is.
