"[FONT=&quot][h=3]Background[/h]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.

[FONT=&quot][h=3]Results[/h]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.

[FONT=&quot][h=3]Conclusions[/h]We show that most Uralic speakers share a distinct ancestry component of likely Siberian origin, which suggests that the spread of Uralic languages involved at least some demic component."

Awesome graphic. Uralic associated mtDNA and Y-DNA lineages juxtaposed with a phylogenetic tree of Uralic languages. I wonder what the reasons for the heavily male-biased spread of Y-DNA lineages in Europe were (taking also non-Uralic Lithuanians into account). Did Uralic speakers have a technological advantage of sorts?

the European branches seem to be the result of mainly male migrations

Hm i'm not sure about the western/eastern gradiant for modern use. Probably early Uralic speaker had very different distribution, more Far East Women and more Siberian Men. Remember that Uralic people with Siberian ancestry, when the appear into the Baltic areas, they found a very WHG-like population, wich is still today the part were WHG ancestry is the most common. The Finnic and Saami group clearly absorb some WHG/EHG pre group who became dominant. The Mordovians,Mari,Permic and Ugric are mostly ancient IE people ( taking account their modern geographical presence and their physical features ) who became Uralised by a migration of Uralic Men and Samoyeds are probably the most representative people to what ancient Uralic people could have been.

My bet is reindeer domestication, you get an ecological niche with low HG density.
