There is no such thing as an inherent "ability to evolve new species" that 
doesn't depend on the environment, which changes.

The idea that few new species _did_ evolve in the last few million years of the 
Cretaceous has long been abandoned: it was based simply on the fact that the 
Campanian record of North America is better than the Maastrichtian record of 
North America.
