I get the whole micro-evolution stuff where creatures breed to improve the species, but we've been breeding fruit flies for a long time and ended up with more fruit flies and not some kind of mutant superfly whose genetic structure is different than the others. (Aside: With whom would such a freak breed to produce viable offspring when its genetic structure wouldn't match its mate's?)
In any case, what hit me was how tied the guy was to Darwinian evolution. He couldn't allow even a single disagreement or objection. It had to be true, nay, it was true and anyone who didn't dogmatically agree was an infidel. As a Catholic, I don't really care one way or another. Recall that we believe that God doesn't make contradictions and that if established science conflicts with theology then theology must change. Science doesn't bother me at all, but miracles or intelligent design don't bother me, either.
So in all innocence, I brought up those objections - how do structural genetic changes occur resulting in fruit flies eventually producing sheep? He went bonkers and threw all manner of snarky, you're-an-ignorant-moron meme images at me.
I hope he had fun doing it. Me, I idly wandered off and had a Firestone Union Jack and watched the Cubs game.
Follow Up: Here's a UC Berkeley bit on the evolution of flight, but it begs the question at hand. I can see how flying is better than not-flying, but I don't see the process at the molecular level. Where did all those atoms come from in the modified genetic codes? Why did the reactions happen instead of producing death and deformity?
