If I understand your question correctly, it would look like Archaeopteryx, because why else would He prompt us to name it that? In other words, if He had intended us to name it Archaeopteryx, he'd have created something that we would name Archaeopteryx, which would be the thing we actually did name Archaeopteryx.
If that's not a good enough answer, it's not because I'm trying to dodge, it's only because I might not have understood what you were getting at. If it is a good enough answer, does that mean you'll answer mine now?
I envision a single dinosaur sprouting little, beentzy wings, unable to fly with but heavy enough to make it less fit to survive.
Then, I picture it being devoured by a t-rex who specializes in eating mutants.
Finally, I see the big evolution roulette wheel spinning and spinning for eons until at long last the cycle and pattern are repeated.
