asians have a lot of denisovan dna too, and there are bone fragments originally attributed to denisovans that were found by DNA to be a 50/50 denisovan/neanderthal mix somewhere in the ballpark of modern uyghur territory atm iirc (some of the only denisovan pieces ever found i believe) hybrids are usually unlikely to be able to reproduce but its not impossible depending on how distant they were, and we simply dont have enough evidence to deny they could have so it could have been neanderthal-denisovan hybrids that went across asia for all we know
