[/qb][/QUOTE]As akachi put it, superficially some of them "Look like" Sub Saharan Africans. This only goes so far as there are African "looking" populations all across the globe. From a Y-DNA perspective, they have [URL=https://genetiker.wordpress.com/2016/06/22/y-snp-calls-from-the-ancient-near-east/]Very Strong[/URL] signatures from Africa. Most in the form of [URL=http://i67.tinypic.com/6p0n86.jpg]E-Z830~[/URL] (The precursor to E-M123) but even one [URL=https://genetiker.wordpress.com/y-snp-calls-for-i1416/]PPNB individual[/URL] could be positive for E2, which puts a bit of E~ diversity in the region. Their Maternal diversity is totally lacking in Mtdna L, not what I would expect of recent SSA Migrants. Autosomally they carry a component that straddles both sides of the Red Sea and seems to peak in more inbred groups of the middle East like Arabs, Especially Saudis. Nearly All East African Eurasian classified ancestry is absorbed in this box. Someone could argue this component is "African" but they will be arguing that Saudis, Yemeni Jews and various populations in the Middle East are 50-80 "African" as well. There are some making this argument, Its silly, I dont exactly buy it.(Unless one is using the larger argument that ALL Western Eurasian autosomal components are "African"......using the technicality of TMCRA's and divergence dates....then your are probably right. a la xyyman) Then there is the argument that the "Natufian" component, or the wide spread autosomal component of the Middle East that becomes nearly fixed in Saudis is partly African. This I do argue and is what to expect when ancient DNA From Africa [URL=http://i68.tinypic.com/2gvpr3l.png]Keep Showing[/URL] what this Ancient DNA from North Africa shows.(That all Middle East Populations carry an component fixed in Ancient North Africans.) This is also what we would expect given the lack of Sub Saharan specific autosomal Ancestry in the Mid East yet the presence of Parental African signatures. Of course in the instance of IAM it is only half the Age of Natufian so Natufian cannot be partly of IAM ancestry......literally. We need older African DNA, something more contemporaneous with Natufian to confirm the affinity...but I think it will stay the same or just become MORE convoluted as we introduce African substructure. This is what is going on in a nutshell. [/QB][/QUOTE]
