Ancient DNA links genetic admixture to language shift in the medieval Upper
Volga
"Uralic languages span a wide geographic area across northern Eurasia, and most of
their speakers share a distinct genetic component. The extant members of the
language family, however, represent only a subset of the former linguistic diversity. At
least three other Uralic languages-Merya, Murom, and Meschera-endured in the
Upper Volga region of central Russia until the Middle Ages. However, during the
second half of the first millennium, the rising importance of Slavic language led to
their gradual demise. Today, traces of these extinct Uralic languages survive only in
historical literature and place names. Thus, the linguistic history of the Upper Volga
region is relatively well known, but it remains unclear how Slavicization affected the
local gene pool over time. In this study, we produced genome-wide data from 32
ancient individuals from the Upper Volga Suzdal region to investigate the subtle
population dynamics associated with the language shift. We find that the Iron Age
population, predating the arrival of the Slavs, was genetically similar to present-day
Uralic-speaking populations of northeastern Europe. This local Iron Age population
contributed a substantial proportion of ancestry to their medieval successors at the
initial stage of Slavicization. In the following centuries, Slavic-like ancestry became
the major component, while Uralic-like ancestry gradually decreased. Both
ancestries, however, remain present in modern-day Central Russians. Finally, we
observed several outlier individuals representing non-local ancestries in our medieval
dataset. These individuals highlight the importance of the medieval Upper Volga
region as a center of far-reaching trade and cultural contacts.”
