[QUOTE]Originally posted by Tukuler: [QB] I think the bottom right quad would look very different if Basal Eurasian (Pleistocene Africa/ Arabian Peninsulars) could be included. Too bad Beduine_A with they Esan and Wambo infused self didn't make the PCA. [IMG]http://i64.tinypic.com/2q2lafk.jpg[/IMG] TL isolated Africans BL at least 5% 'admixed' Africans BR West Eurasians & admixed EEFs TR East Eurasians [QUOTE]Originally posted by beyoku: [qb] @ Elmaestro. [QUOTE] an extremely narrow definition based on genetic diversity were [b]"Eurasians" start NOT at a geographical point but instead a figurative genetic cornerstone[/b] (All the way at the bottom.) [IMG]http://i64.tinypic.com/adoxt3.png[/IMG] Yes in this narrow definition the [b]diagonal line from Khoisan all the way to the bottom would represent African diversity with genetic "Eurasians" starting at Sardinians[/b] and ancient farmer samples. While its funny, I am not quite ready to say that, instead i think and old enough sample from Egypt would show something different....somewhat how the Natufian was modeled as part North West Africa in Oracle. Egyptology just doesnt support mass migration in antiquity. We have to account for African substructure. The ancient DNA from Kenya and Sudan may help a lot with it. [/QUOTE]They are calling it Eurasian based on what they assume about geographic populations and NOT based on some Isolated ROOT population on that PCA. IN the Above PCA "Basal Eurasian" would be on the African cline, "Natufian" would be on the African Cline.....and definitely Any Egyptian population that contributed to Natufian. As for a lingering NE African component, we could find it but we likely need Ancient DNA that will split a population multiple ways in the way it did for Europeans removing their genetically "Homogeneous" status.....NO instead they are a combination of 3-4 different groups. BE was conceptualized a long time ago. [/qb][/QUOTE] [/QB][/QUOTE]
