[QUOTE]Originally posted by xyyman: [QB] No! xxyman is 100% right Quote: “Tagging Archeological sites with Uniparentals? Xyyman is ‘slightly right’ about "West African" E-M2 being kinda young. ……...” The point on E-M2. There are indigenous nodes of E-M2 in North Africa(which was hidden and NOT reported by other researchers per this paper). Significance? E-M2 cannot possibly be of West African origin. It will not be found in aDNA of West Africans. Next, we need to do a node-by-node break down of E-M2 regarding age and location. ElMaestro is part right ….But the Sahel was the conduit from East Africa to North and West Africa. Sahel was not where it originated. If E1b was included that would have helped nail it down. But irregardless, there is clearly indigenous E-M2 found in North Africa that has absolutely nothing to do with “slavery”….and that is what he researchers set out to prove. [IMG]https://s13.postimg.org/clq8kx1yf/E-_M2_in_North_Africa.jpg[/IMG] recap ________________________________________ I am not done reading but....wow...this is a bomb shell study. It looks like they are exposing the lies. Are they breaking rank? Lol! As I predicted. Are they accusing past researchers of doctoring results and/or hiding information? SMH Are they saying that E-M2 dispersal are from North Africa? This I getting good. He! HE! He! As Kdolo said. Within their admission of their past lies they replace it with another lie. They provided no data for European version of R-V88, bummer! Quote --------------------- Outside the African continent, two rare R-V88 sub-lineages (R-M18 and R-V35) have been observed in Near East and southern Europe[b] (particularly in Sardinia).[/b] Because of its ethno-geographic distribution in the central Sahel, R-V88 has been linked to the spread of the Chadic branch of the Afroasiatic linguistic family. In spite of their genetic differentiation, however[b], northern and sub-Saharan Africa **share** at least four patrilineages[/b] at different frequencies, namely A3-M13, E-M2, E-M78 and R-V88. In this context, rare Y lineages with a relic [b]geographic distribution can be highly informative regarding human migrations across the Sahara.[/b] Thus, considering their frequency distribution, the four trans-Saharan lineages A3-M13, E-M2, E-M78 and R-V88 could[b] represent the remains of the Saharan MSY genetic landscape before the desertification, CONTRARY to the USUAL interpretation involving recent gene flow events such as the trans- Saharan Arab slave trade.[/b] In order to [b]investigate the role of the last Green Sahara in the peopling of Africa, [/b]we performed targeted next generation sequencing (NGS) of ~ 3.3 Mb of 104 Y chromosomes mostly belonging to these four lineages. We also analysed the geographic distribution of 142 informative single nucleotide polymorphisms (SNPs) by genotyping about 8000 male subjects from 145 worldwide populations (including 17 populations from literature), with a particular focus on the African ethnic groups. Our findings[b] were consistent with the hypothesis that the Green Sahara allowed extensive human movements,[/b] excluding recent historical events, such as the Arab slave trade, as a major determinant of the male gene pool of present-day northern African populations. [b]four precisely radiocarbon-dated ancient specimens as calibration points [/b](Additional file 1: Table S1). In the set of 104 samples from our lab collection, we identified 5966 SNPs.[b] Interestingly, 3044 variants (51 %) out of the 5966 were *******not reported in previous studies***** [/b]and this figure is significantly greater than that reported by Hallast et al. [QUOTE]Originally posted by Elmaestro: [qb] .. Xyyman posted a botched version of it. E-M2 is at the very least Sahelian (possibly Chadian.)
