It's time to have a look at the Scythian steppe warrior from the Mathieson et al. dataset. This is the first Scythian individual to be genotyped. He comes from the eastern end of the Pontic-Caspian steppe, is dated to 380-200 calBCE, and belongs to Y-chromosome haplogroup R1a, which is the dominant Y-haplogroup in Scythian and related remains tested to date. His genome-wide data puts him closest to Northeast and Northwest Europeans from among present-day populations, rather than West and South Asians, who should, in theory, carry significant Scythian ancestry. We can probably put this down to the complex ancestry of West and South Asians. Moreover, he can be modeled as a mixture of the Middle Bronze Age Potapovka people of the Pontic-Caspian steppe and present-day Nganasans of Siberia. This gels rather nicely with archaeological evidence, which suggests that Scythians were the descendants of Bronze Age Eastern European migrants to South Siberia, who expanded west across the Eurasian steppe during the Iron Age and eventually ended up back in Europe.
