In June, two studies published in Nature revealed the complexities of ancient Eurasian population genomics and the cultural impacts of population migrations. Both studies found evidence that one group of nomads--the Yamnaya steppe herders--entered Europe around the Late Neolithic/Early Bronze Age, likely bringing with them Proto-Indo-European language. One study found these nomads also brought a light skin variant into Europe, but not lactose tolerance. These researchers suggest that the Yamnaya also spread eastward, into the Altai mountains. These results confirm the cultural similarities (particularly their burial practices and pottery styles) archaeologists have noticed between the Yamnaya and the Bronze Age peoples in the eastern Eurasia.
