I know of no evidence that species have "stopped adapting", do you? 
Species adapt over thousands and millions of years.  

Hasn't most of the current carnage occurred within the past 150 years
(since the Industrial Revolution)?  This is probably too short of a
period to "adapt" genetically.

Also, there is evidence that a lot of species extinction is due to
habitat shrinkage.
