Anatolian I.E



Fig. 2 Principal component analyses using ancient and present-day genetic data.
(A) PCA of ancient and modern Eurasian populations. The ancient steppe ancestry cline from EHG to Baikal_EN is visible at the top outside present-day variation, while the YamnayaKaragash_EBA sample has additional CHG ancestry and locates to the left with other Yamnaya and Afanasievo samples. Additionally, a shift in ancestry is observed between the Baikal_EN and Baikal_LNBA, consistent with an increase in ANE-related ancestry in Baikal_LNBA. (B) PCA estimated with a subset of Eurasian ancient individuals from the steppe, Iran, and Anatolia as well as present-day South Asian populations. PC1 and PC2 broadly reflect West-East and North-South geography, respectively. Multiple clines of different ancestry are seen in the South Asians, with a prominent cline even within Dravidians in the direction of the Namazga_CA group, which is positioned above Iranian Neolithic in the direction of EHG. In the later Turkmenistan_IA sample, this shift is more pronounced and toward Steppe EBA and MLBA. The Anatolia_CA, EBA and MLBA samples are all between Anatolia Neolithic and CHG, not in the direction of steppe samples.

The genetics of an early Neolithic pastoralist from the Zagros,Iran.

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.
