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.

It seems like I recently read the Bantu expansion started about 2k years ago but 3k is close enough. I wonder if the ghost existing in khoisan is Bantu input or independent.

I think the truth is beneficial for everyone in general as fibs just grow and obscure everything and progress. Fibs help no one except our "leaders"

I wonder if that's true about east asians, I've definitely read in multiple places they have slightly more neanderthal and about 2% denosvian on avg. Even among like the north chinese.

If the same ghost exists in those islanders Id say it's pretty close to proof positive that out of africa isn't true. Obviously if they both have the same ghost and no one else does it's not possible the rest of us evolved from them. Ofc that would quickly lead to the question of how the f they got to those islands without mixing.

Personally I'm very convinced at this point that the story we've been given basically amounts to pharisitical leaven.

Interesting conversation, thanks for that.
