A genetic study by Yelmen et al. (2019) however shows that modern South Asian populations are generally closest to West-Eurasians. They concluded that modern South Asians are basically a mixture of a native South Asian genetic component and a later-arriving West-Eurasian component (derived from both West Asia and the western Steppes). The authors also argue that the native South Asian genetic component is distinct from the Andamanese or East Asians, and that the Andamanese are thus an imperfect proxy. They propose that the South Indian tribal Paniya people (a group of predominantly ASI ancestry) would serve as a better proxy than the Andamanese (Onge) for the "native South Asian" component in modern South Asians, as the Paniya are directly derived from the natives of South Asia, while the Onge may have received geneflow from other groups.
