Australopithecus et al. is a truly ancient African story. At some point, around a million years ago, Homo erectus left Africa and colonised the globe (well OK not Australia or the Americas, but everywhere else). H. erectus evolved over time into 3-4 disinct species, include H. sapien (in Africa), H. neanderthalis, the Denisovans and H. Rudoplhensis, if that's still considered a separate species. The Out of Africa hypothesis does not refer to the exodus of H. erectus (which was never controversial), but that of H. sapiens nearly a million years later. The countervailing view point was that H. sapiens left Africa and merged (or assimilated) with the indiginous species, the so called Multiregional hypothesis. Genetics have shown that Out of Africa is mostly correct, with just a dash of Multiregionalism. In reference to an earlier multiregionalism, we're probably just too distant from other non-African apes, such as the Orangutan for any significant hybridisation to occur. We're more than 15 million years separated from them. But - I'm no expert either, but I know one, who I guess would tell you all of that.
