Still, your emphasis on genetics while failing utterly to comprehend natural selection indicates to me that you don't understand it. Some of these variations make certain members of the population more likely to survive and pass on these variations to the next generation. This results in a shift in the gene frequencies in a population toward the variations that are more suited to the environment. If you do not understand genetics, you cannot understand how natural selection works. That is a factual statement, not one in which the proof rests on the possession of educational transcripts.
Evolution is the central principle of biology.
Your statements do reveal, however, that you don't understand how it works. I do not believe religious stories necessarily as literal. But I do understand their mythic significance as their source of truth, something that frees me from theological dogma and makes the stories of all religions accessible for moral guidance. Ecology and evolutionary biology are where my interest lie, not in microbiology. I am also more generous than you because I have nothing to prove.
