1 - Is there scientific consensus that there are 260,000 year old Homo Sapiens fossils in China? Other fossils, yes (after all, Erectus and possibly more left Africa nearly two million years ago) 2 - Are you saying that Australo-Melanesians carry DNA which is not just Denisovan and Neanderthal and not that other archaic unknown species suggested? Denisovan and Neanderthal DNA isn't found in Africa either, generally, but that statement of course just means that what makes Neanderthals and Denisovans _different_ from the originating African populations isn't found in Africa. Neanderthals and Denisovans are still considered an "Out of Africa" population. I can't see anything in what you listed which is different from Out of Africa, plus a little intermixing with earlier migrations (e.g. Neanderthals and Denisovans, and potentially others). That would fully explain why you see some "old" DNA in some populations. It's still Out of Africa, again because 96-98 % of the DNA of any person on Earth is from a (relatively) recent exodus out of Africa. This is still extremely different from the older multi-regional hypotheses.
