[QUOTE]Originally posted by the lioness,: [QB] [QUOTE]Originally posted by Elite Diasporan: http://www.cell.com/cell/fulltext/S0092-86741731008-5 Reconstructing Prehistoric African Population Structure Pontus Skoglund, 2017 __________ Many on the site Forumbiodiversity were certain this pastoralist would be more "Cushite-Like" with lineages like E-V22/M1 instead we get what I call "true Bantu Negroid" L2a1. [/QUOTE] [QUOTE] We found that the ∼3,100 BP individual (Tanzania_Luxmanda_3100BP), associated with a Savanna Pastoral Neolithic archeological tradition, could be modeled as having 38% ± 1% of her ancestry related to the nearly 10,000-year-old pre-pottery farmers of the Levant (Lazaridis et al., 2016), and we can exclude source populations related to early farmer populations in Iran and Anatolia. [/QUOTE][b]So in the thread topic article how did they determine the L21a Tanzanian woman of 3,100 BP was 38% Levantine? [QUOTE] [/b] Below another article but talking about African origins of L2a1 https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4515592/ [b]60,000 years of interactions between Central and Eastern Africa documented by major African mitochondrial haplogroup L2[/b] Marina Silva,1 Farida Alshamali,1,2 Paula Silva,1,3,4 Carla Carrilho,5,6 Flávio Mandlate,5,7 Maria Jesus Trovoada,8,9 Viktor Černý,10 Luísa Pereira,a,1,3,4 and Pedro Soares1,11 L2a1 (26.5 ka in ML and 29.6 ka in BI) is the most complex sub-clade within L2a and it harbours lineages from all African regions, as well as lineages from other continents, including non-African branches, such as L2a1l2a (connected to Ashkenazi Jewish Diaspora35,36), and the exclusively European L2a1k37. Phylogenetic reconstruction of L2a1 is often difficult due to high levels of homoplasy. Major splits within L2a1 defined by homoplasic positions (143, 16189, 16192 and 16309) exist for parsimonious reconstruction purposes but will not be considered in the text. L2a1a has clearly a Western/Central African origin and distribution, with many sub-clades suggesting a recent Bantu migration southwards, and is hardly present in Eastern Africa. This pattern is also visible in L2a1c, L2a1f and L2a1i. L2a1e and the minor clade L2a1m exist essentially only in Western/Central Africa. L2a1l displays a similar pattern in sub-Saharan Africa, but with the peculiarity of a sub-branch present in Ashkenazi Jews, L2a1l2a35. L2a1b again shows an origin in Central Africa, but subclade L2a1b1a dating to 6.9 ka in ML is present in Southern Africa and has a few lineages in Eastern Africa (mainly Somalia). It might have moved earlier to the East in the Early Holocene and incorporated later by Bantu migrants. L2a1d splits into an Eastern African sub-clade (L2a1d1) at ~10.6 ka and L2a1d2 that shows a split between a Western African lineage and a Southern African clade dating to about 7 ka that contains the star-like L2a1d2a clade dating to 3.7 ka. Other clades show additional evidence of an early migration into Eastern Africa, like L2a1h and L2a1j. We detected a new clade specific to Somalia, L2a1r, at 7.3 ka. The clade L2a1 + 143 shows several basal Eastern African lineages (together with Near Eastern and Arabian lineages) that indicates a migration in the Early Holocene. Minor clades, namely L2a1g and L2a1q, are present in Bantu-speaking populations in the South and, although they were not detected in Western/Central Africa, their lower age suggest a direct involvement in the Bantu expansion. L2a1b contains Somali lineages, whose founder age in Eastern Africa is 7.9 ka [1.5; 14.5] and the Eastern African L2a1d1 dates to 10.6 ka. L2a1h, probably with Eastern African origin, dates to 14.4 ka while L2a1r, a newly labelled Somali clade, dates to ~7.3 ka. Additionally, around 20% of Eastern African lineages cluster within the L2a1 + 143 branch (24.8 ka in ML). A founder age of this cluster suggests a migration time at 14.8 ka [10.2; 19.5], pointing to a migration in the Late Glacial or postglacial period. Overall, as predicted by HVSI-I data, most of the L2 lineages entered Eastern Africa between 15 and 7 ka. [/QUOTE] [/QB][/QUOTE]
