He made a prediction based upon the idea of evolution and common descent. You may not like the fact that he predicted it and was shown to be correct, but there you have it.

Can you explain how it was a “discovery after the fact” or do you just want to move on to a new lame excuse why this wasn't a prediction based upon the theory of evolution?

He "described" something. That's not quite like "predicting" something. He did not predict that at some future time men and apes will follow different evolutionary paths.

That's something that already happened.

He didn't predict the technology it took to describe the nucleic differece between men and apes. Really blew it in fact. There's not the slightest inkling that anyone in Darwin's day had regarding DNA. Doublehelix simply didn't fall from their lips eh.
