I should stress, to avoid confusion, that being genetically closest to a given population is not the same as being directly descended from that population. Modern peoples with the highest Sintashta/Andronovo ancestry per se tend to be speakers of Iranian, Turkic, and Indo-Aryan languages from Central Asia, South Asia, and parts of West Asia (Iran, Kurdish-majority areas, Turkey) and Northern Eurasia (Russia/Siberia). Sintashta/Andronovo admixture probably occurs in the highest proportion in Iranian-speaking Pamir groups, some of whom have it at ~50% even today.
