Proto-Indo-European kinship system and patrilineality


Within months, it will be finally confirmed that both Late Repin offshoots – Early Yamnaya and Afanasievo – spread with clans that were dominated by R1b-L23 patrilineages. Succeeding migration events, likely coupled with internal founder effects under the most successful clans, left Indo-Tocharian-speaking clans as an almost uniform community in terms of Y-chromosome haplogroups, with their most recent common ancestor traceable to the 5th millennium BC.

Before that, it seems that the Indo-Anatolian-speaking Early Khvalynsk community was slightly more diverse. In particular, the success of R1b-V1636 lineages is apparent in the Khvalynsk-Novodanilovka expansion, since it is … Read the rest “Proto-Indo-European kinship system and patrilineality”

Long-term matrilineal continuity in a nonisolated region of Tuscany


New paper (behind paywall) The female ancestor’s tale: Long‐term matrilineal continuity in a nonisolated region of Tuscany, by Leonardi et al. Am J Phys Anthr (2018).

EDIT (10 SEP 2018): The main author has shared an open access link to read the PDF.

Interesting excerpts:

Here we analyze North-western Tuscany, a region that was a corridor of exchanges between Central Italy and the Western Mediterranean coast.

We newly obtained mitochondrial HVRI sequences from 28 individuals, and after gathering published data, we collected genetic information for 119 individuals from the region. Those span five periods during the last 5,000

Bantu distinguished from Khoe by uniparental markers, not genome-wide autosomal admixture


The role of matrilineality in shaping patterns of Y chromosome and mtDNA sequence variation in southwestern Angola, by Oliveira et al. bioRxiv (2018).

Interesting excerpts (emphasis mine):

The origins of NRY diversity in SW Angola

In accordance with our previous mtDNA study9, the present NRY analysis reveals a major division between the Kx’a-speaking !Xun and the Bantu-speaking groups, whose paternal genetic ancestry does not display any old remnant lineages, or a clear link to pre-Bantu eastern African migrants introducing Khoe-Kwadi languages and pastoralism into southern Africa (cf. 15). This is especially evident in the distribution of the
