[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by Elmaestro: [b]Swenet[/b] makes a good point... [QUOTE]BTW, this is also why I'm very sceptical of claims that the non-SSA ancestry in Africa (e.g. Luxmanda) is actually PPN. It's anachronistic as it does not fit the aforementioned trend of homogenization. [b]Luxmanda's so-called PPN could easily be something EEF-related + various components of which some are African[/b], because that is exactly what PPN is also. I think when predynastics are sampled, their non-SSA ancestry will show a preference for PPN and Natufians (compared to EEF). But, taken literally, this is similarly bogus for all the aforementioned reasons.[/QUOTE]I cosign the Model, but to me whatever falls inline with being EEF-like is simply NorthAfrican Ancestry shared between European Neolithic Groups... [b]Which I believe is supported by the ruling out of Anatolian Admixture (Skoglund 2017).[/b][/QUOTE]IIRC, they just ruled out an Anatolian source—not an Anatolian contribution. It seems to me that, if Luxmanda's non-SSA part specifically resembles PPN, as the authors claim, then part of it would have to be Anatolian Neolithic. [QUOTE]Originally posted by Elmaestro: the remainder of Luxmandas ancestry not shared with African groups in the paper is more related to the Near east (some if not all is actually due to admixture FMPOV)... regardless, this doesn't happen with a archetypal African Basal Eurasian subgroup existing, unless its North African... how does that Idea hold up with NAfrican aDNA, KEB can't be Basal Eurasian like, ...IAM, maybe, however, if you can prove introgression from Ibermaurasians and Model the remaining outgroup as both African but not SSAn... But once again, I don't know how well this is supported by archaeology[/QUOTE]I don't understand what you mean here. But if you maintain that Basal Eurasian is Iranian or Arabian, then you can't say that the African ancestry in Luxmanda, IAM and KEB is underestimated. The biggest common denominator in the non-SSA ancestry of all these populations is Basal Eurasian. If you maintain that Basal Eurasian is not African, then you're essentially saying the same thing as Polako (i.e. that only the SSA-like ancestry in these populations is African). [/QB][/QUOTE]
