Now we have to define "ape" and "human" in such a way as to know the difference between the two.

As far as I know that's already been done.

Obviously, we'll have to discard the contemporary definition of "ape", since nobody asserts that modern members of the ape family led to humans.

Not sure how that follows, but I'll grant that you've avoided my latest questions.

Well, we obviously can't lean on the modern definition of "ape" - none of those animals are ancestors of humans, that much is for sure. So if we want to see if some "apes" evolved into humans, we'll need to look somewhere else for our ape.
