Yes, you tried. Anyway, is there a difference in evolution and simple natural selection? I would not argue about the finches or the moths in England or the many varieties of dogs. I would call that "natural selection." Evolution in my view refers to the progression, for example; of lemur to monkey to man. Or dinosaur to bird.
I would not want to argue that with these definitions, "natural selection" proves evolution.

That's the mechanism for change. Just add eons of time and you have variation from the original which is radical enough to cause humans to classify them into a different species. Long enough time and classification into a different genus. Long enough time and classification into a different family, etc.
