If we evolved from The Hominidae family then how come Chimps, Orangs, Gorillas still exist? Why haven't they turned into us? They continue to breed and make the same species and we continue to breed and make the same species. I've never seen a human give birth to a chimp or have seen a chimp give birth a human. Have you? Even if a human tried to breed with a chimp the chimp would not give birth to a half-human/ half-chimp hybrid. No conception results at all.
