It's the Darwinist agenda. As with climate science, it's difficult to make your case (on either side of the spectrum) on a topic that would take untold years to prove. Regarding animal evolution , it would be wonderful (so says the Darwinist) if we could prove that evolution is not only happening, but happening "even faster than we thought."
(Now where have you heard that before?)
I think this is why the push right now in zoological circles is for splitting two subspecies that FREELY interbreed into two species. As I said in my previous post, a "split" is a way of "proving" that the process of evolution continues at an expeditious pace.
And the purpose of this is...?
