[QUOTE]Originally posted by the lioness,: [QB] Oh , I see the whole other section when you hit the methods tab [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] [QUOTE] METHODS (excerpt) Here, we used a model with 19 populations (Mbuti, Dinka, Mende, South_Africa_2000BP, Tanzania_Luxmanda_3100BP, Ethiopia_4500BP,[b] Levant_Neolithic (PPNB),[/b] Anatolia_Neolithic, Iran_Neolithic, Denisova, Loschbour, Ust_Ishim, Georgian, Iranian, Greek, Punjabi, Orcadian, Ami, and Mixe), using previously published complete genomes (Fu et al., 2014, Lazaridis et al., 2014, Mallick et al., 2016, Meyer et al., 2012) and ancient DNA data enriched using the 1240k SNP set (Lazaridis et al., 2016, Mathieson et al., 2015) to maximize the power to infer admixture proportions for the ancient African populations. These populations, and in particular the ones from Africa, were chosen to capture major strands of ancestry and extremes in population differentiation found in sub-Saharan Africa (Figure 1) Support for a single out-of-Africa founding population Simple tree models suggest that non-African variation represented by Sardinian, English, Han Chinese and Japanese falls within the variation of African populations. To test whether non-Africans are indeed consistent with being descended from a homogeneous population that separated earlier from the ancestors of a subset of African populations – beyond the known effects of archaic admixture in non-Africans – we used African populations with little or no known West Eurasian mixture (South_Africa_2000BP, Mbuti, Biaka, Mende, Ethiopia_4500BP, Dinka) and [b]tested whether they are consistent with being an unrooted clade with respect to a diverse set of non-Africans (Orcadian, Onge, Mixe, Motala_Mesolithic, Japanese, Anatolia_Neolithic) using qpWave (Patterson et al., 2012, Reich et al., 2012).[/b] We found that this model was consistent with the data (p = 0.53) (transition SNPs excluded to a final set of 110,507 transversion SNPs). Even when we add New Guinean highlanders to the set of non-Africans, the single-source model for the out-of-Africa founders is not rejected (p = 0.11). [/QUOTE]wikipedia: [b]PPNB[/b] Pre-Pottery Neolithic B (PPNB) is a Neolithic culture centered in upper Mesopotamia. It was typed by Kathleen Kenyon during her archaeological excavations at Jericho in the West Bank. [/QB][/QUOTE]
