how much variance does evolution theory explain?

University of Chicago: Wu suggested: "The slowdown in genetic evolution in the more advanced organs makes sense," he said, "only when one takes a systems perspective."

I'm surprised at the use of this finding as an argument for evolution theory.
Is evolution theory 'the big theory of everything' it claims to be or does it play a more modest role?

Or is Wu right and can evolution slow down when an organism reaches a high level of organisation?
