[QUOTE]Originally posted by Amun-Ra The Ultimate: [QB] What comes out of most studies about Tuareg (and Berber) is: 1) Heterogeneity. Not all Tuareg have the same population genetic structure 2) Mostly African hg on the male side, and a large non-African hg proportion on the female side (from different geographic origin populations). 3) Genetic drift effect drastically changing the ancient population structure among those populations. For example, Tuareg in Mali (Tgos) are 100% African on the male side (ABE hg) but only 28.5% African (L hg) thus 71.4% non-African (HUVM) on the female side. MtDNA haplogroups like H and L didn't originate in the same region, among the same population. Taking from: [i]Linking the sub-Saharan and West Eurasian gene pools (2010)[/i] In the same study, Tuareg in Niger are determined to be 66.7% African on the Male side (ABE hg) and on the female side 80.6% African (L hg), that is of course 19.4% non-African on the female side (HUVM). Although even real geneticists sometimes consider M1 to be African, sometimes not, but their proportion is smaller. Maybe the Tuareg in Niger, having more African hg, are, while admixed, closer to the original "unadmixed" Tuareg or maybe on the contrary their African Hg are more recent. In 2 other studies ( [i]First Genetic Insight into Libyan Tuaregs: A Maternal Perspective[/i] and [i]Deep into the roots of the Libyan Tuareg: a genetic survey of their paternal heritage[/i] ), we got: Libyan Tuareg MtDNA Non-African (H1+V+M1) 61+4+2=67% African L:33% And Y-DNA of Libyan Tuareg, African E=91.4% Non-African R+other=8.5% Although Libyan Tuareg show a low level of haplotype and nucleotide diversity (one of the lowest in Africa according to study). Similar situation with Berber population and their high proportion of E-M81. Showing us the effect of genetic drift. Thus meaning that the modern representative of the Berber and Tuareg don't have the same genetic population structure, the same haplogroup proportion than in the past. Some haplogroups have drifted away while other haplogroups are now over-represented. High level of genetic drift shows us that the ancient Tuareg and Berber population didn't have the same genetic structure and haplogroup distribution that the modern population. There was a drift. It's also interesting to note that almost none of the non-African Tuareg and Berber specific hg like H in Tuareg or M81 show up in Beyoku's study preview (beside one M1 in OK and MK). [b]The closer a Tuareg or Berber is to African populations and haplogroups, the closer he is to the Ancient Egyptian population[/b]. Which is true of course for any populations since Ancient Egyptians are closely related to African people genetically. The closer a population is to Africans, the closer you are to Ancient Egyptians: Old Kingdom (2686-2181 BCE): ySNP, mtDna A-M13, L3f A-M13, L0a1 B-M150, L3d E-M2, L3e5 E-M2, L2a1 E-M123, L5a1 E-M35, R0a E-M41, L2a1 E-M41, L1b1a E-M75, M1 E-M78, L4b J-M267,L3i R-M173, L2 T-M184, L0a No MtDNA HUV, one M1. No Y-DNA M81. From this thread: http://www.egyptsearch.com/forums/ultimatebb.cgi?ubb=get_topic;f=8;t=008622;p=1 Nor did DNA tribes study which included Berber and North African populations find any close matches with the North African region. A region which faced many foreign invasions since ancient times: Phoenicians, Romans, Vandals, Byzantines, Arabs, Turks, French, etc. Which changed its genetic structure (the haplogroup proportion) along the years. http://dnatribes.com/dnatribes-digest-2013-02-01.pdf http://dnatribes.com/dnatribes-digest-2012-01-01.pdf Tuareg and Berber, from an African point of view, are a population which started in East Africa, like most modern Africans, and migrated eventually to Northwest Africa to finally interbred with people from the Iberian peninsula and back migration from the Middle East in Ancient and more modern times. Eventually came about the effect of genetic drift (which can be seen by the high proportion of M81 or HUV hg). Moors means black even if now many Berbers have white skin, showing us that in ancient times almost all the original Berbers were black. [/QB][/QUOTE]
