That's how science works. People throw things out there and other people try and poke holes in it. The stuff they can't poke holes in stays around until somebody can. Peer review and all. Don't know why you put Neanderthal and Australopithecine on your list unless you're trying to debunk the "missing link" strawman.
More BS. Neanderthals were as "modern" as you and I, fully human. Australopihecines were extinct apes.
