[QUOTE]Originally posted by Djehuti: [QB] ^^ [QUOTE]Originally posted by Elmaestro: [qb] The distinct local component in the east wont be that distinct due to the fact that Eurasian ancestry [b]would likely [URL=https://www.researchgate.net/publication/325967278_What_is_Africa_A_human_perspective]be a subset of it.[/URL][/b] Also, 30kya Eurasian ancestry which is likely distinct from Natufian Ancestry(due to levant_Chl mostly forming their own component), that is likely to be shared by more Africans extant and extinct than their contemporaneous Eurasian counterparts is truly hardly Eurasian. Furthermore, in [URL=https://www.pnas.org/doi/10.1073/pnas.1800851115#supplementary-materials]Fregel et al. 2017, [/URL] download the supp and Look at the genetic distances between [b]Taforalt[/b] and every one else, [b]Natufian[/b] and everyone else, [b]IAM[/b] and everyone else and [b]yoruba[/b] and Eurasians. Can you confidently and intellectually honestly state for the board that you believe that a Eurasian component, [b]increased the genetic distance between IAM and other Eurasians[/b] from their predecessors? Can you confidently state that that same Eurasian component [b]decreased the distance between IAM and Yoruba[/b] in relation to their predecessors? Can you intellectually state that a Eurasian component which permeated Africa that long ago is indeed Eurasian but not represented well in Natufians and their likely descendants Levant_Chl? If not Natufians which Eurasian population should we liken this ancient Eurasian ancestry to? What you wanted to pass off as ANA is now framed in a different light. The distinct North West African component had been parsed out due to the West African related ancestry forming it's own component. Hadza also formed their own component in the run, though their ancestry was reduced to noise amounts in Taforalt. I warned you that Aterian ancestry will likely be west_African related but you insisted it was ANA. So here we have it, this shared dark green component is not West African related, it absorbed Taforalt's Hadza related ancestry, and it follows the same ANA distribution pattern [URL=https://revoiye.com/update-ana-related-admixture-in-select-populations/]calculated a couple years ago.[/URL] [b]Does this precious 30Kya Eurasian ancestry in Africans have Aterian-ANA ancestry?[/b] Why or why not? [/qb][/QUOTE]Come now Askia and Elmaestro, your valid questions might prove too much for the poor guy. Recall Tishkoff's 2000 [URL=https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1287905/]STR polymorphism study[/URL] [i] These studies suggest a recent and primary subdivision between African and non-African populations, [b]high levels of divergence among African populations[/b], and a recent shared common ancestry of non-African populations, from a population originating in Africa. The intermediate position, between African and non-African populations, that the Ethiopian Jews and Somalis occupy in the PCA plot also has been observed in other genetic studies (Ritte et al. 1993; Passarino et al. 1998) and could be due either to shared common ancestry or to recent gene flow. The fact that the Ethiopians and Somalis have a subset of the sub-Saharan African haplotype diversity [b]and that the non-African populations have a subset of the diversity present in Ethiopians and Somalis makes simple-admixture models less likely[/b]; rather, these observations support the hypothesis proposed by other nuclear-genetic studies (Tishkoff et al. 1996a, 1998a, 1998b; Kidd et al. 1998)that populations in northeastern Africa may have diverged from those in the rest of sub-Saharan Africa early in the history of modern African populations and that a subset of this northeastern-African population migrated out of Africa and populated the rest of the globe. These conclusions are supported by recent mtDNA analysis (Quintana-Murci et al. 1999).[/i] Also, in Antalas's other thread on [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=010760]Old Kingdom aDNA[/URL] which he has yet to respond, I posted: [QUOTE] Then we have Tishkoff's 2009 autosomal study which was discussed in a thread on Mozabite Berbers [URL=http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=006835]here[/URL], wherein she stated: [i] Within Africa, genetic diversity estimated from expected heterozygosity significantly correlates with estimates from microsatellite variance (fig. S4) (4) and varies by linguistic, geographic, and subsistence classifications (fig. S5). Three hunter-gatherer populations (Baka and Bakola Pygmies and San) were among the five populations with the highest levels of genetic diversity based on variance estimates (fig. S2A) (4). In addition, more private alleles exist in Africa than other regions (fig. S6A). Consistent with bi-directional gene flow (14), African and Middle Eastern populations shared the greatest number of alleles absent from all other populations(fig. S6B). Within Africa, the most private alleles were in southern Africa, reflecting those in southern African Khoesan (SAK) San and !Xun/Khwe populations (fig. S6C) (12). [b]Eastern and Saharan Africans shared the most alleles absent from other African populations examined[/b] (fig. S6D).[/i] 'Saharan Africans' is her term for North Africans. [IMG]https://1.bp.blogspot.com/-2xNTTvUat3U/T324J53neBI/AAAAAAAAAZU/vSBQ1Z3jfnw/s1600/Tischkof_5B.jpg[/IMG] ^ Note the blue color represents alleged "Eurasian" ancestry. It should not come as a surprise that the 'Cape Couloured' folk of South Africa who descend from natives mixed with colonial whites and Asian immigrants have it. The presumption then is that Saharan populations like the Beja and especially Mozabite also posses it due to admixture, but Tishkoff cautions against such thinking especially since the Sub-Saharan Dogon carry it also! [b]Dogon[/b] [IMG]https://t4.ftcdn.net/jpg/05/71/74/51/360_F_571745192_OZ4knHKQlIaxpNgcnB9Cz7sExGxkhQXv.jpg[/IMG] ^ The Dogon look no different from 'typical' Sub-Saharans i.e. "negroes" which are the only people Antalas would call 'black', yet they carry more Eurasian autosomal alleles than Mozabites![/QUOTE]Any answers to this?
