ADAPTATIONS AND DISTRIBUTION 



and habit patterns are emphasized, not because morphological changes are 

 unimportant, but only because they have already received sufficient emphasis 

 in studies of evolution. It is not intended to overetnphasize habits, lor this 

 would be as unsound as the neglect of them has been.
