Elmaestro Member # 22566	posted Genetic Ancestry of Hadza and Sandawe Peoples Reveals Ancient Population Structure in Africa Daniel Shriner Fasil Tekola-Ayele Adebowale Adeyemo Charles N Rotimi quote: Abstract The Hadza and Sandawe populations in present-day Tanzania speak languages containing click sounds and therefore thought to be distantly related to southern African Khoisan languages. We analyzed genome-wide genotype data for individuals sampled from the Hadza and Sandawe populations in the context of a global data set of 3,528 individuals from 163 ethno-linguistic groups. We found that Hadza and Sandawe individuals share ancestry distinct from and most closely related to Omotic ancestry; share Khoisan ancestry with populations such as ≠Khomani, Karretjie, and Ju/’hoansi in southern Africa; share Niger-Congo ancestry with populations such as Yoruba from Nigeria and Luhya from Kenya, consistent with migration associated with the Bantu Expansion; and share Cushitic ancestry with Somali, multiple Ethiopian populations, the Maasai population in Kenya, and the Nama population in Namibia. We detected evidence for low levels of Arabian, Nilo-Saharan, and Pygmy ancestries in a minority of individuals. Our results indicate that west Eurasian ancestry in eastern Africa is more precisely the Arabian parent of Cushitic ancestry. Relative to the Out-of-Africa migrations, Hadza ancestry emerged early whereas Sandawe ancestry emerged late. https://academic.oup.com/gbe/advance-article/doi/10.1093/gbe/evy051/4935243 ..This man again lol. I trust Tekola-Ayele though.

Ancestral composition of the reference pseudo-samples used in the semi-supervised clustering analysis.” He is trying to make a name for himself. Henn and Eva Gonzalez did the same. Then they capitulate. Eva - 50% African lineage in prehistoric Iberia. African lineage in 8kyo Farmers in Levant...They all do it then fall in line. Whole-Genome-Sequence-Based Haplotypes Reveal Single Origin of the Sickle Allele during the Holocene Wet Phase - Daniel Shriner1 No need to "TRUST" him??!! He will fall in line. Maybe in this paper. Let's see....
xyyman Member # 13597	posted These people are Fugking hilarious… -------------------- Quote: “Semi-supervised analysis is called supervised analysis in ADMIXTURE (Bansal and Libiger 2015) and can be performed by invoking the option --supervised. Supervised analysis based on predefined allele frequencies that are not allowed to be updated by the sample genotype data is called projection analysis in ADMIXTURE and can be performed by invoking the option -P ( For the unsupervised analysis, we filtered our reference set to exclude samples with Asian and/or European ancestry. Shringarpure, et al. 2016 ). Supervised analysis is not recommended if there are ancestries missing from the panel of predefined allele frequencies.” ---------------- xyyman comment: They refuse to do a direct comparison with Europeans doing an unsupervised analysis which I have been calling for for years to resolve this. Lol! Phew! Lol! I give up! Ha! HA!

Let's see.... I'm not starting a relationship with the man... when I say trust I mean "worth the read," based on the methods and format. I have no reason to be paranoid, cuz I actually *understand* what I read and reread. I'm tryna get you on my level but I guess they were right when they say you can't teach an old dog new tricks.
xyyman Member # 13597	posted more supervised/data manipulation. They just can't help themselves. At least they call a spade a spade. Say when they are cheating...SMH
Elmaestro Member # 22566	posted Yes, they (An African and the first researcher to openly report Natufian SSA ancestry in a scientific article) are out to suppress the truth about African genomics. ...At least pretend you know what you're talking about sometimes mane lol.

Old Dogs don't do 💩 lessn u pay us 1st 🤑 Hmm no emoticons that look like me but Poop got that buck eye melon lips thing goin on. On the for real side I have the African researchers and Shriners 2016 supplements where they over tax Treemix but convincingly interpolate even a 7 migrations tree with male uniparental HGs. And they give enough f-stat math to make David Blackwell or even Ramanujan kn**. Haven't read Shriner & Rotimi's work with Ms Baker.
Fourty2Tribes Member # 21799	posted Our results indicate that west Eurasian ancestry in eastern Africa is more precisely the Arabian parent of Cushitic ancestry. Huh? So they use ancestry in place of relationship then instead of relationship they use parent for Arabian? An African Researcher wrote that?
capra Member # 22737	posted the Arabian component being the ancestor is based on some literal reading of TreeMix and half-assed uniparental stuff. it is all Wednesday afternoon blogpost level of analysis AFAICT. actually their Cushitic component is closest to their Berber component. but i got lambasted for proposing North African origin of Cushitic ancestry lol

Huh? So they use ancestry in place of relationship then instead of relationship they use parent for Arabian? An African Researcher wrote that? I'm tired from a very long day and hope I am reading this right. But are they saying that the Eurasian admixture in Cushites is not Levantine but instead Arabian?
