Новая статья по гаплогруппе J2.

A new paper has just come out on the Neolithic to Bronze Age transition of Southeastern Europe. As we know the earliest J2 and J2a samples come from around the Caspian Sea — either the Caucasus or Northern Iran (Hotu Cave). Now it appears that the group of which these earliest J2’s were a part may have been the originators of Indo-European languages, spreading them first to Anatolia and then from there into early Greece and Europe as a whole. In line with this there are some very early instances of J2a and J2b found in Eastern Europe that are 5,000 bc, or 7,000 ybp.



“One version of the Steppe Hypothesis of Indo-European language origins suggests that Proto- Indo-European languages developed north of the Black and Caspian seas, and that the earliest known diverging branch – Anatolian – was spread into Asia Minor by movements of steppe peoples through the Balkan peninsula during the Copper Age around 4000 BCE.47 If this were correct, then one way to detect evidence of it would be the appearance of large amounts of steppe-related ancestry first in the Balkan Peninsula, and then in Anatolia. However, our data show no evidence for this scenario. While we find sporadic examples of steppe-related ancestry in Balkan Copper and Bronze Age individuals, this ancestry is rare until the late Bronze Age. Moreover, while Bronze Age Anatolian individuals 372 have CHG-related ancestry, they have neither the EHG-related ancestry characteristic of all steppe populations sampled to date, nor the WHG-related ancestry that is ubiquitous in Neolithic southeastern Europe (Extended Data Figure 2, Supplementary Data Table 2). An alternative hypothesis is that the ultimate homeland of Proto-Indo-European languages was in the Caucasus or in Iran. In this scenario, westward movement contributed to the dispersal of Anatolian languages, and northward movement and mixture with EHG was responsible for the formation of a “Late Proto-Indo European”-speaking population associated with the Yamnaya Complex. While this scenario gains plausibility from our results, it remains possible that Indo-European languages were spread through southeastern Europe into Anatolia without large-scale population movement or admixture.” (p. 9)

So the Indo-Europeans were not the Yamnaya but the J2 individuals who came from the Caucasus/Caspian/Nth Iran region. A very significant result for our haplogroup, I’d say, if it stands up.
