I’m going to justify that statement below, and also explain a little bit about the scientific facts about vertebrate development. I know that many of you on here are YECs, and that’s just fine —– I don’t care what people believe, I only care if they distort the science to justify those beliefs, and when people do that I will call them on it and correct them. Because if, as a creationist, you want to challenge science, you have to at least know what the science is, and the way that scientists have interpreted the data. That is, even if you disagree with the interpretation, you have to know the facts. It does no good at all to muddle the facts up and then present them (especially to a scientist who both reads and writes the primary literature) as some sort of “look how absurd evolution is” claim, as Chuck so graciously mansplained to me the other day about scientists saying that whales evolved from hippos.
