[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by the lioness,: [qb] [QUOTE]Originally posted by Ish Gebor: If L3 was in Africa 70.000 years ago due to back migration, and is younger than L1, L2 while L3 which mostly comprises with “sub Sahara” Africans from the Sahel, Steppe and Sahara region. It can only mean that they migrated back from Asia carrying all these so called Eurasian genetic mutations along with them. :D This paper confirmed the history of the Asiatic black man. [/QUOTE]Amazing ! [/qb][/QUOTE]Indeed. And to you it doesn’t matter the amount of ridiculousness and crazy stuff they write, although it doesn’t add up, you’ll still accept it as long as it is in support of Eurocentric B.S.. There are clear contradictions in the things you post and have posted throughout the years, with the acception, that they all claim a Eurasian back-migration into Africa. :D [QUOTE] Within the human mitochondrial DNA (mtDNA) tree, haplogroup L3 encompasses not only many sub-Saharan Africans but also all ancient non-African lineages, and its age therefore provides an upper bound for the dispersal out of Africa. An analysis of 369 complete African L3 sequences places this maximum at ∼70 ka, virtually ruling out a successful exit before 74 ka, the date of the Toba volcanic supereruption in Sumatra. [...] The L3 mtDNA pool within Africa suggests a migration from Eastern Africa to Central Africa ∼60 to 35 ka and major migrations in the immediate postglacial again linked to climate. The largest population size increase seen in the L3 data is 3–4 ka in Central Africa, corresponding to Bantu expansions, leading diverse L3 lineages to spread into Eastern and Southern Africa in the last 3–2 ka.[/QUOTE]—Pedro Soares et al. The Expansion of mtDNA Haplogroup L3 within and out of Africa Molecular Biology and Evolution, Volume 29, Issue 3, 1 March 2012, Pages 915–927 Funny how: [QUOTE]In this study we presented only haplogroups displaying interesting results. A local evolution in Tunisian Berbers was observed in haplogroups L2a, L3*, and L3b. [...] Our results demonstrate an ancient local evolution in Tunisia of some African haplogroups (L2a, L3*, and L3b). The most ancient haplogroup is L3*, which would have been introduced from eastern sub-Saharan populations to North Africa about 20,000 years ago. [...] Our results also point to a less ancient western African gene flow to Tunisia involving haplogroups L2a and L3b. Thus the sub-Saharan contribution to northern Africa starting from the east would have taken place before the Neolithic. The western African contribution to North Africa should have occurred before the SaharaÂ’s formation (15,000 BP). [/QUOTE]--Frigi et al.
