In view of the far too great emphasis that has been laid on the 

 developmental stage reached by individual species in assigning them 

 to a place in the system, and also of the far too common practice of 

 regarding characters of arrested development or aquatic adaptation 

 as primitive, it is perhaps not out of place to emphasize a somewhat 

 different view.
