[QUOTE]Originally posted by Ish Gebor: [QB] [QUOTE]Originally posted by the lioness,: [qb] Swenet, is there a Lazaridis quote that explicitly states the geographical location of "non-African" ? Is it safe to assume that "non-African" were people who lived outside Africa exclusively? That seems logical by the title[/qb] https://i.imgbox.com/bMrlOpUV.png [/QUOTE]Remarkable isn't, the proximity? [IMG]http://i63.tinypic.com/10cmfl2.jpg[/IMG] [QUOTE] [i]Dataset preparation for population genetic analyses Genotypes were called in GD13a at sites which overlapped those in the Human Origins dataset ([b]Lazaridis et al.[/b]17, filtered as described in Jones et al.24) using GATK Pileup44.[/i] [/QUOTE] [QUOTE] [b]The site has been directly dated to 9650)9950 calBP (11), showing intense occupation over two to three centuries.[/b] The economy of the population has been shown to be that of pastoralists, focusing on goats (11). Archaeobotanical evidence is limited (16) but the evidence present is for two)row barley, probably wild, and no evidence for wheat, rye or other domesticates. In other words the overall economy is divergent from the classic agricultural mode of cereal agriculture found in the Levant, Anatolia and Northern Mesopotamian basin. […] [b]We compared GD13a with a number of other ancient genomes and modern populations (6, 17–29), using principal component analysis (PCA) (30)[/b], ADMIXTURE (31) and outgroup f3 statistics (32) (Fig. 1). GD13a did not cluster with any other early Neolithic individual from Eurasia in any of the analyses. ADMIXTURE and outgroup f3 identified Caucasus Hunter)Gatherers of Western Georgia, just north of the Zagros mountains, as the group genetically most similar to GD13a (Fig. 1B&C), [b]whilst PCA also revealed some affinity with modern Central South Asian populations such as Balochi, Makrani and Brahui (Fig. 1A and Fig. S4)[/b]. Also genetically close to GD13a were ancient samples from Steppe populations (Yamanya & Afanasievo) that were part of one or more Bronze age migrations into Europe, as well as early Bronze age cultures in that continent (Corded Ware) (17, 23), in line with previous relationships observed for the Caucasus Hunter)Gatherers (26). [...] Figure Legends: Fig. 1. GD13a appears to be related to Caucasus Hunter Gatherers and to modern South Asian populations. A) PCA loaded on modern populations (represented by open symbols). Ancient individuals (solid symbols) are projected onto these axes. [b]B) Outgroup f3(X, GD13a; Dinka), where Caucasus Hunter Gatherers (Kotias and Satsurblia) share the most drift with GD13a. Ancient samples have filled circles whereas modern populations are represented by empty symbols.[/b] C) ADMIXTURE using K=17, where GD13a appears very similar to Caucasus Hunter Gatherers, and to a lesser extent to modern south Asian populations. http://oi63.tinypic.com/e8r4nk.jpg http://oi65.tinypic.com/24zap2b.jpg [...] S4. Mitochondrial Haplogroup Determination The mitochondria of GD13a (91.74X) was assigned to haplogroup X, most likely to the subhaplogroup X2. Haplogroup X2 is present in modern populations from Europe, the Near East, Western and Central Asia, North and East Africa, Siberia, and North America (7). Haplogroup X2 has been associated with an early expansion from the Near East (7, 8) and has been found in early Neolithic samples from Anatolia (9), Hungary (10) and Germany (11). [/QUOTE] [QUOTE]S5. Principal component analysis shows that Southern Asian populations are the closest contemporary populations to the Iranian herder GD13a was placed close to the Southern Asian samples, specifically between the Balochi, Makrani and Brahui populations of South Asia. (Fig. S4). Of the ancient samples, GD13a falls closest to hunter-gatherers from the Caucasus (Fig. S4). [/QUOTE] [QUOTE] S7. Outgroup f3 statistics show that GD13a shares the most genetic drift with Caucasus Hunter-gatherers [b]We used outgroup f3-statistics to estimate the amount of shared drift between GD13a and contemporary populations. This was performed on the dataset described in section S6 using the qp3Pop program in the ADMIXTOOLS package (13). We computed f3(X, GD13a; Dinka), where X represents a modern population and Dinka, an African population equally related to Eurasians, acts as an outgroup (Fig. S7).[/b] We also repeated this analysis where X represents ancient individuals/populations. Among the ancient populations, Caucasus hunter-gatherers (Kotias and Satsurblia) have the closest affinity to GD13a (Table S3), followed by other ancient individuals from Steppe populations from the Bronze age and modern populations from the Caucasus.
