[QUOTE]Originally posted by Swenet: [QB] [QUOTE]Originally posted by Tyrannohotep: If memory serves, [qb]the big OOA event took place between 70-50 kya.[/qb] So Basal Eurasian emerging as a distinct component ~80 kya would make it older than OOA itself. The implications of this should be obvious by now. ;) [/QUOTE]It's actually less than 55kya for the mtDNA M and N people according to the latest research. But this doesn't say anything about other OOA migrations (it doesn't include OOA migrations started by people who didn't belong to mtDNA M and N), of course. Modern uniparentals hide other OOA migrations, while autosome-derived split times conflate different OOA migrations. Important to keep in mind because that is partly why these OOA dates are all over the place. According to Posth et al 2016 (the last big paper dedicated to dating OOA): [IMG]http://marketbusinessnews.com/wp-content/uploads/2016/02/Major-population-change-in-Europe-14500-years-ago.jpg[/IMG] [QUOTE]Dating the most recent common ancestor of each of the modern non-African mtDNA clades reveals their single, late, and [b]rapid dispersal less than 55,000 years ago.[/b][/QUOTE] https://www.ncbi.nlm.nih.gov/pubmed/26853362 mtDNA M and N-linked OOA migrations might have taken place entirely in between 50-40ky ago.
