[QUOTE]Originally posted by Amun-Ra The Ultimate: [QB] [QUOTE]Originally posted by Swenet: [qb] ^Correct, and the report seems to be saying as much when they put an upper bound of major SSA admixture at 94kya, even though they're dating the M,N split from L3 at a much younger date. This definitely reeks of isolation of the AMHs that are ancestral to Eurasians. Djehuti thinks this isolation was in Africa, I do too. He says this makes them African, geographically, I say that is irrelevant. Geographically they are, but the Y chromosomes (Eurasian specific M168) and mtDNAs their descendants became known for, have no further history in Africa other than simply spawning there and leaving what seems to be the first imprint on the ancestors of modern Africans only 30-20kya in the form of U6 and M1, which is equivalent to Henn et al 2012's Maghrebi component. [/qb][/QUOTE]I disagree with some aspect of the second part. Henn is a euronut or a eurasian nut who tries to deny any African presence in North Africa in ancient time and even himself only talk about *likely* maghrebi ancestry. Accent on "likely". So he's not even sure of what he's talking about. The Frigi study completely contradicts him in that sense. For example, Henn doesn't see any African DNA in North Africa Ancient time!! (by using strangely enough only West African DNA). He concludes there's no such thing in North Africa. He only sees recent African DNA in North Africa. He attributes all non recent middle eastern DNA mutations to some "native" DNA from some ancient West Asian back migration (but isolated from the rest of west Asia for many years, which he calls "likely autochthonous Maghrebi ancestry"). He's proven to be wrong by the Frigi study (as well as some archeological data). Henn's "likely" supposition (because that's what it is a supposition) is identified precisely by Frigi as a very Ancient African component in North African people DNA. The [URL=http://www.ncbi.nlm.nih.gov/pubmed/21082907]Frigi study[/URL] shows us that there was indeed Ancient black African presence in North Africa. Which are a small part of the genome of modern coastal North Africans and even explain the small part of the DNA erroneously attributed to some likely autochthonous Maghrebi ancestry DNA by Henn but attributed to ancient African presence in North Africa by Frigi. It is more likely than any back migration from West Asia (including Hg U6, etc) have been met by an ancient black African presence in North Africa and interbred to some degree with them. Remnants of this ancient African presence in North Africa also still live today usually in the south of North African countries and in the Sahara. [/QB][/QUOTE]
