Another batch of ancient mtDNA from the Dnieper Basin


This set of results is from a multidisciplinary study on the Mesolithic to Neolithic transition in Ukraine (see here). The mtDNA haplogroups include two C, two T, one U3 and one probable U1.

The paper is part of an open access e-book which features many other articles on prehistoric Europe and Asia: Population Dynamics in Prehistory and Early History (2012).

Despite the small sample and lack of Y-DNA data, I'd say that this is a fairly useful effort. That's because it again shows the presence of South Siberian-specific maternal lineages on the North Pontic steppe during the Neolithic, and gives weight to the scenario that there was a movement of people from the east of the Urals to Europe at a very early timeframe (for more on that, see here and here).

East Eurasian lineages were represented by the C clade (Ya34 and Ya45), which is uncommon in ancient or present-day European populations, but is found in Neolithic populations, as well as contemporary populations from South Siberia, where this lineage is most likely originated (Starikovskaya et al., 2005; Mooder et al., 2006).

Of interest in this context is the fact that the analysis of Neolithic cemeteries of the Baikal region has suggested that a depopulation event occurred in that region during the 6th millennium BP (Mooder et al., 2006). As such, the dating of Yasinovatka (at ca. 6440–6080 [Hedges et al., 1995]) suggests that there is a possible link between the Baikal depopulation event and the appearance of the C lineage of mtDNA in the North Pontic region.

About the "kurgan aDNA R1a " from the sites like Andronovo in which SNP they showed +Ve results? Z280,Z283,SRY10831.2,M17?

SNP -> M17+

Y-STR haplotypes -> 100% R1a-M417+ (maybe R1a-Z93+/L342 more likely?; maybe R1a-Z283/Z280 less likely?)


Dawid,
>>> So the story unfolding here is that Near Eastern Neolithic migrants, carrying mtDNA T, and possibly Y-DNA R1a, migrated to Europe, and settled on the North Pontic steppe. Here they mixed with Mesolithic Europeans, who mostly carried mtDNA U lineages, and unknown Y-DNA haplogrops (possibly I2?), as well as migrants from Siberia.

Or Mesolithic (East-Central) Europeans were R1a-M198 (with older?), R1a-M417 (Z85- later:"L664" and Z85+(or Z645,Z647) later:Z283 i Z93). I2/I1 then it West/South Mesolithic Europeans. :)

Thanks! About Z93 its most frequent in Indians with more worldwide presence than Z280, Z283 etc.
Good times.
