EVOLUTION AS A NATURAL PROCESS 129 



ual contest carried on by the members of one commu- 

 nity has been done away with. It is an inexorable law 

 of nature that all living things must fight daily and

 their living foes and the decimating conditions of in- 

 organic nature are the first to die, while the others 

 will be able to prolong the struggle for a longer or
