IN the following paper, taken almost entirely from Darwin's 

 Aiiima/s and Plants 7mder Domestication^ I have been able 

 to choose only a few out of the innumerable interesting and 

 important examples of natural and artificial selection given in that 

 wonderful work. Indeed, the whole section dealing with variation
