EVOLUTION AND HUMAN DESTINY 



However as shall soon be discussed, the implications of 

 this material and scientific advance reach far beyond 

 the obvious and are of the greatest significance when 

 examined from the over-all point of view of tracing 

 the development of the human societal organism. 



In the human colony specialization of individuals is 

 taking place to an increasingly noticeable extent. So- 

 ciety today is becoming ever more dependent upon the 

 specialized skills of many groups. At the present time 

 it is certainly no longer possible for any one individual 

 to be proficient at all the skills that are now essential 

 for the continued functioning of organized society. 

 Various groups of specialists certainly differ to a 

 marked degree in their average mental characteristics. 

 In extreme cases they may even show differences of 

 physical characteristics which are statistically measur- 

 able and significant. As an example, one would expect 

 lumberjacks and chemists, when considered as groups, 

 to show such physical differences. The extent to which 

 specialization has proceeded is greater in the more ad- 

 vanced cultures than in the more backward ones. In 

 modern civilization specialization is fostered more and 

 more by the society itself. The fact that the activities 

 of these various groups are reasonably well integrated 

 into the total workings of society, without the neces- 

 sary conscious control of any one individual, is indeed 

 remarkable. This phenomenon is often regarded as 

 just a matter of fact situation, without recognition that
