[QUOTE]Originally posted by Elmaestro: [QB] [QUOTE] [b]Tukuler[/b] That type of inference fell apart at K= 16 where with the * "Masai-maximized East African component", * "a component maximized in the East African Hadza", and * "an African farmer component maximized in the Yoruba" there's no room for anybody else in Dinka ancestry. Laz's f3-stats about Dinka show his * Syrians, * Saudis, and * Polish Jews are admixed with Dinka. Cases of outside bloodlines in Africans remain showing through to the max K, like the bars for the Black Americans and the Ethiopian Jews for instance. [/QUOTE]Did you ever get around to reading [URL=http://bit.ly/2oozL7e]Stora[/URL]? I forgot to warn you that its not much of a remarkable study in relation to what we're speaking about, but if you compare ADMIXTURE results with Lazaridis (2014)involving ancient specimens & African populations you see a trend. And as you wisely pointed out after I made the mistake of calling the Dinka [i]"Western-Sahelian & Admixed[/i], The Dinka aren't OOA admixed, which makes them the best proxy (so far) for an East African Admixture coefficient, next to MOTA. [i]Was gonna PM you, but might as well post this for public disclosure[/i] [IMG]https://s23.postimg.org/eupf0drbf/Admixture_East_Africa_west_and_European_farmers.png[/IMG] To your credit as you stated in this thread, Admixed Africans Maintain their signal @ K=20. Because I mentioned Mandinka having Sahelian components [i] (which entails OOA Admixture, Yadda yadda), [/i]I Kept them as the west African example of what you pointed out. Their admixture signals along with African Americans remain consistent & proportional through K20. The same can not be said about East Africans though. Lazaridis Estimated a ~44% Basal Eurasian score for EEF, meaning about 44% of their genome is a result from shared drift from a population who most likely had little to no Neanderthal admixture. @ K=9 in his study (2014) and K=12 in Stora/Kılınç, (2016) referenced above (pink @ K-12), A near eastern and European HG-like cluster develops and in the Ancient European samples (EEF in particular) About 40-50% of EEF contains shared drift with Near eastern populations (exemplified by the Bedouin clusters). This as I stated earlier is probably the best look we can get of the proposed "Basal Eurasian" But look at what happens to the East African populations as admixture is calibrated as a result of an East African cluster. I'm sure you're already onto this but even more importantly Look at what happens to the Near East component in EEF when the Bedouins form their own cluster @ K=20. Matterfact It becomes even more glaring if you look at Lazaridis 2014. At K20 Light blue = European shared drift with CHG (side note, This cluster seems to follow Jewish populations) Green = Sardinian/ Southern European, cluster. ...Btw, Any good discussions on the population history of the Sandawe?
