In all honesty, Ayla and her tribes people don't make sense, from an evolutionary stand point. 65 million years is a long time for evolution to take place. They do not appear to be any pre-human species, they look exactly like normal humans. I'd have to say that they were homo sapiens, although, I'll amend that: homo sapiens archaic Mind you, it's been a while since anthropology, but I do recal that being a valid species of near-humans.
