"No No No!" shout the evolutionists. "Apparently you haven't evolved sufficient brain capacity to understand!
"Evolution works because each environment is different, and evolution works by adapting each species to their environment."
That's an example of the pragmatic fallacy: the argument that something is true because it works ... when the meaning of "works" is vague and implies, "It's as much explanation as we need."
Or did I mean the ad hoc fallacy instead?

I've read pro-evolution arguments suggesting that the evidence in favor of evolution is so convincing, if a scientist really wanted to attract attention and make a name for himself, all he'd have to do is come up with proof that evolution doesn't work.
Implying of course, that no scientist anywhere can reasonably dispute evolution because if such a person existed, that scientist would become famous overnight.
But that's circular reasoning ... assuming your argument to be true because you believe it.

See, I'm guessing if a scientist really wanted to draw tons of attention to him/herself overnight, and have his/her name carved in scientific stone ahead of both Darwin's and Newton's, answering the question How Did Life Start? would sure do the trick.
