Of course it's an answer. You're pretending to be dense. I'm going along with your gag. It's that whole "humor" thing. You should try it.
Pick a species. Say Crocodylia. Whatever of it is alive today has remained virtually unchanged for vast amounts of time.
You know this. I know this. You can *pretend* that some semantical issue warrants debate, but you are merely prolonging your inevitable loss of (probably) yet another debate.
Your call. Keep pretending. Keep nitpicking semantics. Won't matter. Won't help you.
So please, carry on dear sir.
