CAUSE OF EVOLUTION 371 



ing, and doubtless at least part of his digesting done for 

 him by machinery. Dentists, barbers and manicurists 

 will turn to more productive forms of labor preceded 

 probably by soldiers, lawyers, and others who make their 

 living on human misery." 



It is only what we should expect when we remember 

 that an animal is a nation or colony of still smaller in- 

 dividuals. If we begin to live on food that needs no 

 grinding, teeth will be useless and will be gradually dis- 

 carded. We, as a nation or as individuals, would do the 

 same thing. Nothing will be produced and maintained 

 except what is necessary and for a purpose. Take for 

 instance the case of bees and ants. They are not as large 

 as man, still they display the same intelligence in refer- 

 ence to their affairs as man. Their social actions and 

 organizations are just like those of man and the cells that 

 build man. The history of the gradual social evolution 

 of the bee is the same as that of man. The following 

 from a newspaper is a good description of it : 



"The bees are like human beings in this : they get the 

 habit of work and sometimes they continue working for a 

 little while even after work becomes unnecessary as you 

 see a rich old man still working, though he need not work, 

 but bees, like others, are spoiled by prosperity, and before 

 long all of them lose the habit of working. 



Buchner, the German scientist, observed that near 

 sugar factories in the Barbadoes, the bees give up the 

 troublesome work of visiting flowers. They soon learn 

 that they can get all the sugar they want all the year 

 round which is what the sons of rich men learn very 

 easily. In warm countries, where flowers bloom all the 

 year, the bees give up the storing up of honey for the 

 winter they forget about the cold and rainy days and 

 only gather enough honey and pollen for each day. To
