llie phenomenon of man has been explained in many ways by 

 man. Our view is that the theory explaining the evolution of 

 other organisms is necessary and sufficiejit for man as well. Cultural 

 evolution is an inevitable consequence of mans biological evolution. 



In this section the evolution of man and of his culture is considered 

 from various aspects. Chapter 12 places in biological perspective 

 a very brief description of what is known of the evolutionary history 

 of Homo sapiens. No special processes appear to be responsible for 

 the origin of man, but with the development of culture and the 

 extragenetic transmission of information, a complication appears: 

 evolution within culture itself. The evolution of man now seems 

 to he a resultant of the interactions between biological evolution, 

 in the usual sense, and this psychosocial evolution. 



One aspect of mans culture is his attempt to deal with the physical 

 universe he perceives around him. His techniques for handling 

 reality determine what reality he sees. Man's understanding of 

 the process responsible for his coming into existence is an aspect 

 of this more general problem and is discussed in the last chapter.
