are initially far more developed than the insects, will, 

 in the event of colony formation, ultimately give rise 

 to far more effective societal organisms than those that 

 can develop directly from the lower forms of life. 



COLONIES OF THE HIGHER ANIMALS 



As shall be discussed in the next chapter, colony 

 formation among the higher animals has proceeded 

 further in man than in any other creature. However it 

 would indeed be surprising if this process were ob- 

 servable in man alone and not among any of the other 

 species of vertebrates. 



The initial phases of colony formation are certainly 

 observable in the herds formed by many mammals. 

 Similar associations exist among many species of fish, 

 as well as among numerous kinds of birds. There are 

 probably very few of the higher animals that do not 

 show some associative tendencies. The rudimentary 

 pattern certainly exists although the process itself may 

 not have proceeded very far. However colonies are 

 not formed overnight. Loose association must neces- 

 sarily precede the tighter one. 



The considerations of this book concern themselves 

 primarily with pattern rather than with mechanism. 

 Nevertheless it should be of considerable interest to 

 analyze some of the specific factors that would tend to 

 favor colony formation among the higher animals. 



Perhaps the most important of these factors is im-
