Got any sauce for that? (not doubting you, I'd just like to read up on it further)
I believe @lucid_seeker is refering to this study on west africans having 2 - 19% of dna from an archaic homoninthat diverged from homo sapiens line 1 or 2 million years ago.

There’s also some reason to believe that the west african/bantu population as well as the east african population (two genetically distinguishable groups) are less “pure” african than hunter gatherer populations like the Khoisan, the pygmies, and the hadza
The first two groups (most africans) have mostly “E” y-chromosomes types which are believed by some to have come from introgressions from eurasia after splitting off from type “D”. This would mean a “back to africa” in terms of their paternal dna. Hunter gatherers have type A and B y chromosomes.
Also even the maternal lineage of these two groups may be from eurasia. The west african/bantu and east african groups have a high frequency of mitochondrial dna type L3 as opposed to L0, L1, and L2 types that are more common in hunter gatherer groups.

Most of human lineage is common to within the last 150 to 300 thousand years, according to most anthropologists. But eurasians et al. have significant admixture from neanderthals and /or denisovans which diverged 1 or 2 million years ago. So our earliest common ancestor may have existed 2 million years ago or more. Our latest common ancestor maybe only 150 thousand years ago. Its not clear cut at all at this stage.
Interesting about the y chromosomes and mtDNA. I was not aware of that, but it would basically support the notion eurasians did indeed have significant input into Bantu populations which seemingly began farming only relatively recently. I'm curious if the same pattern appears in other groups of people with similar features such as those living on islands in the Indian ocean. I am also curious if this ghost DNA exists in khoisan or pygmy groups.
We shall see if the out of africa idea holds up as more information is gathered on this subject, personally I don't think it will, but I am fairly certain that most anthropogists will continue to support it until proof of it's untenability reaches the masses in critical mass.

It appears there is some admix in khoisan and pygmy but the most is in west africans.
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.

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...
It turns out you are right, there is another ghost population existing in andaman islanders. I just found this.
Thank you for those sources, you are a class-A bro.
I will enjoy my laurels as an honorary bro today. Thank you.
Yeah I like hard sources over references from breitbart articles or whatever,
Im by no means an expert on this stuff but Im slowly piecing together my understanding of what the archeological/genetic data is saying about this stuff. Obviously there’s a lot of politics injected into this field.
Nukeisrael was an old user from voat who isnt around anymore but he had a lot of interest in this stuff so he and I used to go round and round on the subject.
7.2-million-year-old pre-human remains found in the Balkans (sciencedaily.com)
There were also other findings that suggests multi-regional evolution such as Dali skull in China and Morocco and genetic testing that show some Africans can have up to 20% archaic hominin DNA which set them back hundreds of thousands of years evolutionary speaking.
This is a relatively new finding, within the last several months it seems. But basically analysis of western sub saharans show "ghost" dna from an unidentified group of archaic hominids. It was present on all the subjects tested, but I believe this was only done on west subsaharans. Assuming it's in all subsaharans it would show we couldn't have come out of africa since it's not present in eurasians or amerindian populations. I'd provide a link but I'd need to google one for you which you can do easily. Robert sephr has a joutube channel and has covered this in several videos as well as a bunch of other shit you might be interested in so I'd start there.
His hypothesis is basically that cro-magnon interbred with several different groups of archaics in different regions creating what we today call races. Obvs we whites bred with neanderthals, asians bred with neanderthals and denisovians and africans who bred with neither of those groups bred with this other group, he believes it was homoerectus.
