A rat becoming a cat would contradict the TOE.
OK, let me get this straight: A rat (or it's ancestors) diverging, and becoming a class of felines, and a class of rodents... contridicts TOE?
So, how would you say that two carnivor mammals do not share the same lineage? And that mammals did not start out small, and "rat-sized"?
