(This post is mostly a Note to Self—I don’t want to forget about the study below—but if other people are interested, that’s great.)
The majority of languages spoken in North Eurasia belong to three language families—Turkic, Indo-European, and Uralic. My native language Finnish is a part of the Uralic languages; the main branches of the family are the Finno-Ugric and the Samoyed.
While there’s rough agreement over where and how Uralic languages developed and spread, and over what types of material cultures were found in the corresponding areas, no-one’s done comprehensive studies on the genetic history of Uralic-speaking peoples before.
This interdisciplinary study, lead by Kristiina Tambets from the University of Tartu, Estonia, compared genome-wide genetic variation of nearly all extant Uralic-speaking populations from Europe and Siberia.
“The genetic origins of Uralic speakers from across a vast territory in the temperate zone of North Eurasia have remained elusive. Previous studies have shown contrasting proportions of Eastern and Western Eurasian ancestry in their mitochondrial and Y chromosomal gene pools. While the maternal lineages reflect by and large the geographic background of a given Uralic- speaking population, the frequency of Y chromosomes of Eastern Eurasian origin is distinctively high among European Uralic speakers. The autosomal variation of Uralic speakers, however, has not yet been studied comprehensively. […]
“Here, we present a genome-wide analysis of 15 Uralic-speaking populations which cover all main groups of the linguistic family. We show that contemporary Uralic speakers are genetically very similar to their local geographical neighbours. However, when studying relationships among geographically distant populations, we find that most of the Uralic speakers and some of their neighbours share a genetic component of possibly Siberian origin. Additionally, we show that most Uralic speakers share significantly more genomic segments identity-by-descent with each other than with geographically equidistant speakers of other languages. We find that correlated genome-wide genetic and lexical distances among Uralic speakers suggest co- dispersion of genes and languages. Yet, we do not find long-range genetic ties between Estonians and Hungarians with their linguistic sisters that would distinguish them from their non-Uralic-speaking neighbours.”
And the conclusion:
“Here, we present for the first time the comparison of genome-wide genetic variation of nearly all extant Uralic-speaking populations from Europe and Siberia. We show that (1) the Uralic speakers are genetically most similar to their geographical neighbours; (2) nevertheless, most Uralic speakers along with some of their geographic neighbours share a distinct ancestry component of likely Siberian origin. Furthermore, (3) most geographically distant Uralic speaking populations share more genomic IBD segments with each other than with equidistant populations speaking other languages and (4) there is a positive correlation between linguistic and genetic data of the Uralic speakers. This suggests that the spread of the Uralic languages was at least to some degree associated with movement of people. Moreover, the discovery of the Siberian component shows that the three known major components of genetic diversity in Europe (European hunter-gatherers, early Neolithic farmers and the Early Bronze Age steppe people) are not enough to explain the extant genetic diversity in (northeast) Europe.”
I find the question of which material cultures may have spread together with which languages absolutely fascinating. Having my own small language / culture be a part of a larger study like this makes it even more special.
I was also surprised to learn that only three Uralic languages—Hungarian, Finnish, and Estonian—are not listed as endangered in the UNESCO Atlas of the World’s Languages in Danger. (I did know that several of the tiniest ones like Mari or the Permic languages have been endangered for decades, but I had thought that some of the Samoyed or Ugric languages had more speakers than that.)
While I doubt these three will go extinct very soon, there’s pressure at least in Finland to adopt more and more loanwords from English. Then again, we three may end up being rather rare, all in all, and I’m not quite sure whether to be alarmed over our potential disappearance or proud of our preciousness—or both.
