Please explain to me what is all this hate for west and obsesion with east and North Africa? Why not be happy with europe where you actually come from? These are serious questions?<br /><br />Stop coping so hard where do u think ethiosemites came from? Africa? Why do u think some modern ethiosemites can trace 40%+ of their ancestry from the middle east? Why are ethiopians only 50% e1b1b where did the h,j,h,u,t haplogroups all common in anatolian groups come from? The clear cut reality is northeast africans have major eurasian ancestry, deal with it.Anonymoushttps://www.blogger.com/profile/08419702985552095688noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-92026197011807266262018-10-11T19:45:42.593-06:002018-10-11T19:45:42.593-06:00Hahaha this is funny article Mota is not real it w...Hahaha this is funny article Mota is not real it was made in a lab in Cambridge.

That's not mere "introgression" nor your typical admixture levels, it's total equalization.<br /><br />Just as Capra says: "The funny thing is how everyone at the low end has about 6-8% Eurasian. If some groups, like the Pygmies, got their share by partial admixture with neighbouring groups, I would expect a bigger range in the degree of ancestry".<br /><br />I could not have expressed better: the near absence of any clinality doesn't make any sense. <br /><br />"... the alternative could be that Mota has perhaps 6% Paleolithic Eurasian admixture that other Africans lack"...<br /><br />Doesn't make any sense either: what the data say is "negative" admixture from any West Eurasian source, Paleo, Neo, modern, whatever.<br /><br />One possibility someone has mentioned could be that the West Eurasian admixture was already there but had not yet affected all Africa so totally and hence Mota, it his isolated mountain refuge (?), had been spared but not his modern descendants (roughly the Ari). <br /><br />But I still think that my artifact hypothesis, that there is a compensatory "pull" from West Eurasia to express an African diversity not well assessed in the analysis, looks very likely. It wouldn't be any true West Eurasian element; just remember that the diversity of Africa is almost the diversity of Humankind, so the ill-controlled components tend to spread out among all humans in randomly variable fractions. Some falls to modern West Eurasians and other, probably much larger, fraction falls to Africans (but is not noticeable).

For example, in the case of African Pygmies, we already knew that neighboring Niger-Congo people had so completely influenced them that they lost their language, and their admixture could have come indirectly through that process. Introgression of Nilotic pastoralists into the Khoisan has been convincingly demonstrated.<br /><br />It is also quite possible that in much of Central and Southern Africa, that the Eurasian admixture may have occurred quite recently, only via Bantu admixture.<br /><br />Certainly, it is plausible that pre-Bantu Africa may have had much more structure than it does. Genetically, it is pretty clear that Mozambique had a population that was as distinct from the Khoisan and more northern East Africans as it was from West Africans. It wouldn't be surprising if the divide between West Africa and East Africa was also more distinct before farming and herding arrived.<br /><br />Playing out your hypothesis, I suppose the alternative could be that Mota has perhaps 6% Paleolithic Eurasian admixture that other Africans lack, which is registering as African rather than Eurasian because modern comparison populations are so different genetically from these Paleolithic Eurasians. But, the presence of Neanderthal admixture in African populations proportionate to their Eruasian admixture used Mota as a reference point, and the absence of Neanderthal admixture in Mota really seems to put the kibbash on that kind of hypothesis.<br /><br />The anomalously old inferred age of the Eurasian admixture in West Africans also suggests that what may be going on is the EEF pastoralists may have introgressed into West Africans (perhaps in the Sahel) when cattle first reached Africa, and that other Eurasian admixture in Africa may be derivative of this pastoralist source. The respective West to East and East to West clines of various Y-DNA E lineages in sub-Saharan African strongly suggests that West Africa and East Africa have not been fully isolated from each other genetically in the last 20,000 years or so. andrewhttps://www.blogger.com/profile/08172964121659914379noreply@blogger.comtag:blogger.com,1999:blog-7315236707728759521.post-14073196658751033212015-10-09T08:12:15.442-06:002015-10-09T08:12:15.442-06:00I'm thinking there may be confounding factors ...I'm thinking there may be confounding factors at play. It's hard to accept that the alleged Eurasian admixture is so noticeable even in the most isolated hunter-gatherer populations. IMO there should be an issue with hidden African ancient diversity that is not being well understood... yet.Majuhttps://www.blogger.com/profile/12369840391933337204noreply@blogger.com
