"We observed that the Kalash share a substantial proportion of drift with a Paleolithic ancient Siberian hunter-gatherer, who has been suggested to represent a third northern Eurasian genetic ancestry component for present-day Europeans.36, 37 This is also supported by the shared drift observed between the Kalash and the Yamnaya, an ancient (2,000–1,800 BCE) Neolithic pastoralist culture that lived in the lower Volga and Don steppe lands of Russia and also shared ancestry with MA-1.36, 37 Thus, the Kalash could be considered a genetically drifted ancient northern Eurasian population, and this shared ancient component was probably misattributed to recent admixture with western Europeans."
