A bantu expansion out of west african seems to have begun about 3000 years ago and continued essentially until the present day, slowly overtaking indiginous hunter gatherer territory in the process. This may have coincided witha population boom due to agriculture or a displacement from their original homelands. 3 to 5 thousand years ago the sarahara was quite habitable. Archeological finds place pygmies in west africa 3000 years ago. https://www.nature.com/articles/s41586-020-1929-1 If pygmies are the indigenous people of cameroon, perhaps the west africans are not that west african. I think it would be very useful to educate “our” blacks that they are not the most african people around, that they displaced khoisan and pygmies from most of their native territories in the last 1 to 3 thousand years, and that they are still encroaching on what little territory these groups still have today in places like SA and Congo. Wikipedia article on denisovans >A 2011 study found that Denisovan DNA is prevalent in Australian Aborigines, Near Oceanians, Polynesians, Fijians, Eastern Indonesians and Mamanwans (from the Philippines); but not in East Asians, western Indonesians, Jahai people (from Malaysia) or Onge (from the Andaman Islands). This means that Denisovan introgression occurred within the Pacific region rather than on the Asian mainland, and that ancestors of the latter groups were not present in Southeast Asia at the time, which in turn means that eastern Asia was settled by modern humans in two distinct migrations.[34] In the Melanesian genome, about 4–6%[19] or 1.9–3.4% derives from Denisovan introgression.[52] New Guineans and Australian Aborigines have the most introgressed DNA,[17] but Aborigines have less than New Guineans. So there is no denisovan dna in andaman islanders. But... https://archive.md/wip/T5Ip9 It turns out you are right, there is another ghost population existing in andaman islanders. I just found this.
