Answer:
I am writing this in response to a letter regarding evolution. Evolution is increasingly solid, not shaky. Darwin’s “theory” or explanation was a way of understanding what he had discovered (which did not include genes, chromosomes, DNA or nucleotide bases). Our explanations now include genetics and the commonality of mutation.
Proofs are solid, not in question by serious scientists. Direct observation is one, which we see in the fact that this year’s flu evolved a little too far from last year’s, so flu shots are less effective this year than we would like them to be.
Fossils tell the story well: whales with legs, dinosaurs with feathers and Tiktaalik. The latter was found in the Canadian north and is part fish, part amphibian, before there were ever any amphibians. Imperfection is a good proof: think of your useless appendix, the very bad design of your ankles, knees, and back (talk to a chiropractor about that). You have big toes because they used to be useful thumbs for your grasping feet.
Many other animals and even plants similarly have flaws that show their evolutionary past. Two large human chromosomes reflect the coming together of two chimpanzee chromosomes each.
Hope it helps,
