So if the species is wiped out, it's evolution; and if it's not wiped out, it's evolution? Doesn't sound like science to me.
I'm no biologist, if you want high quality answers you'll have to go find one to ask. But I'm pretty sure you have some wrong ideas about how evolutionary biology works as a field. They observe reality and form theories that fit what they've perceived thusfar. They make predictions based on those theories. Subsequent discoveries can confirm their predictions, or confirmation may remain elusive. It works basically the…
I've learned through personal experience that it's not sufficient to discuss this with a professional biologist. I've found several biology PhDs ill prepared for this topic. I discovered that even at the PhD level some biologists take evolution on faith without having a decent understanding. I think it's much better to read books or view lectures created by specialists in the field specifically for the purpose of confronting evolution skepticism.
