[QUOTE]Originally posted by Elmaestro: [QB] [QUOTE]Originally posted by beyoku: I think you have missed out on the publications to understand exactly what the is saying. He is speaking on North East Africa having a genetic substratum. And pockets of populations in SW Asia having this North East African substratum. It similar to something like E-M35 originating in the Horn yet horners getting MORE E-M35 lineages from North East Africa AFTER they have been affected by A3b2, J1 and and K2. [/QUOTE]I like this comparison for what’s being explained however admittedly the explanations or theories on this matter posted here on ES have been broadly left to interpretation. For instance where these OOA migrants are returning from, whether there were mass migrations or merely continuous geneflow and most importantly WHEN did these interactions begin to take place. I can see exactly why certain positions can be seen as “neohamitocism” 1. It isn’t exactly clear what a pristine A.Egyptians autosomal profile would look like. 2. Near eastern genetics will always take precedence of SSA not only because of Biases but also because of homogenization. 3. The magnitude of OOA correspondence will be exaggerated in Egypt because of bidirectional influence AND divergent population history between North Africans and other Africans who settle in the Sahara or more south/west. With all of these uncertaincies being presented with an explanation that Egyptian ancestry was “brought back” to pioneer Egyptian civilization can be unsettling. Here’s why using your example... you make it aceptionaly clear that m35 originated in the horn... but the lineages that came back A3b2 J1 and K etc. Didn’t, it’s the same with the downstream m35 lineages that came back. They might have descended from a Horner lineage but V32 isn’t Horner. Same can be said about the autosomal counter parts to these sublineages. Natufians and Neolithic Levantine who have african ancestors are not African, their autosomal make up in totality is not African. So if you say Egyptians waited on their own dna to be brought back them it can come across as sketchy. This is even further complicated by the advent of lazaridis’ basal Eurasian red herring. Why? Cuz going back in time with the few sample we have from africa and even some of the very old Eurasians we see a higher amplitude in genetic variation. Though the new data isn’t presented this way and is downplayed by the go to human genome reference panel there are ancient genes/components unaccounted for in modern human variation. Taforalt and IAM makes this clear as day! Despite populations like the Sahawari and southern morrocans showing acceptional continuity... the disparity in actual non African influence in their DNA sticks out like a sore thumb.. and this is with Southern Europeans BRINGING BACK North African dna to morrocco. With people focusing on basal Eurasian being a.egyptian they lose sight of the possibility that Egyptians who migrated out of Africa first carried genes that were undoubtedly outside of Eurasian variation and STILL is.
