Heredity is the passing of traits from parents to offspring.
Natural selection is the process by which some living things succeed in creating more offspring than others.
Once you have those two factors in a system, evolution is occurring.
Speciation occurs when the drift between two gene pools becomes great enough that individuals from the two pools can no longer create fertile offspring.
But the fact that you said "we haven't seen a fish turn into a frog" suggests your misunderstanding of evolution goes well beyond what I can provide in a forum post.
Granted, my "fish to frog" statement was a bit simplistic. I am also not knocking natural selection or heredity, I believe both of those things occur. However what I am saying is that that is not evolution. In the article you cited it talked about evolution being the "change in the gene pool of a population over time" this is where the problem arises. An amoeba has no where near the gene pool of a fish. You can't just make more genes- its like energy there's only so much of it in the universe. I'm not saying that it can't change forms I'm just saying it can't get any bigger. Yet that is what is necessary for evolution to occur. Also you have not answered my question about the huge gap in the fossil record. Like I said, as a skeptic, I just don't see the evidence to support this theory. Just my two cents
