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.
