I remember this drawing, or one similar to it, which was supposed to convince my young skull full of mush that since embryos of humans, amphibians, dogs, birds, and reptiles kinda sorta looked alike, then they must all be related. This was published in textbooks long after it was proven to be a fake. If it's such ironclad, settled science, then why all the fakery?
That cartoon also tells me a lot about people who want me to believe in evolution based on the evidence to date.
School textbooks are riddled with errors. There was one notable case where a geography textbook showed the Equator running through Kansas.
It's hardly the fault of the supporters of the TOE that education bureaucracies in this country do a poor job of fact-checking science textbooks.
