ZOOGENESIS 



saw that these man-like mental attributes were always 

 coupled with some heavy liability, usually feeble and 

 defenseless young. 



We now are able to see further. The man-like 

 attributes of the insects, birds and rodents, and a few 

 other creatures, are correlated with the possession of 

 jaws, beaks or other structures which are capable of 

 being used more or less after the fashion of our hands. 

 Wherever such occur the ability to make use of them 

 enables their possessors successfully to meet and to 

 overcome liabilities which otherwise would be in- 

 superable. In other words, these structures permit 

 the existence of liabilities without danger to the 

 species; the liabilities themselves do not induce the 

 appearance of man-like attributes. 



In the complicated homes built by the ants, bees, 

 wasps and termites are females which never leave 

 them, constantly producing eggs, and hence an enor- 

 mous serial family of dependent young. It is the 

 elaborate home that makes this possible, and the deft 

 and skillful jaws of the adults, coupled with their 

 powers of defense, make the home possible. 



So the lesson that we learn from the study of ani- 

 mal forms in the broadest sense is that it is the home 

 and associated features that form the foundation of 

 the human social structure; in the home originated, 

 and from the home emanated, all our social progress.
