They are not official at all, but they are official in that they are real and exist, so I am talking about samples that are also allegedly V13+ SNP confirmed, one from 2000. BC, the second around 1200-1000. BC, both are preceded by Kapitan Andreevo ie Pšeničevo samples.
The older one according to my constructions (which are based on leaked information) is from the Hatvan culture, the younger one is certainly from some Gava or neighboring variant, it can't be anything else. The older one has close to 40% yam genetics, the younger one close to 50%, but almost all other Hatvan-Fuzeshabonj culture samples seem to have 90% farmer genetics with very little steppe. Those samples were named in that study as Hatvan-Fuzešabonj because they are autosomally radically different from the standard Fuzešabonj samples that have much more steppe and are generally R1a-Z280. In the earlier BD, that locality is Hatvani, later it is Fuzešabonj, so it seems that they are domiciled Hatvani.
I also know the ispilon chromosome and the autosomal profile of almost all the other sites from that study, that's how I got to Hatvan by the method of elimination, because of that sample I spent tens of hours analyzing the material at one time, going to the most extreme extreme to identify each sample so that whatever remains must be that older V13. So I know almost everything from that study, ie. series of studies. In any case, Gava has V13+ in late BD.
They have much more steppe than other Hatvans, it is very possible that this more southern Thracian profile came from outside the Balkans. If these samples are placed in an archaeological context, then it is clear that V13 originated from Hatvan, i.e. and northern farming oases.
Therefore, there is a culture in Pannonia that autosomally was distinctly farming even in the Middle BD. There are no officially published findings, but there are 100% still unpublished.
The Thracian language in that case comes from Fuzešabonj-Ottomani R1a-Z280, or from some Z280 with which Hatvans had connections. Because that language has nothing to do with Yaman or Iranian languages, even according to known linguistic parameters. The closest is the Baltic group.
In any case, the occurrence of V13 in Gava or a related culture, I do not see what has to do with any farming element from the Balkans, which would have been found by now if it existed. And even if it existed, then in that case it would have to be somewhere towards Anatolia.
However, the occurrence of V13 in early and late BD in Pannonia simply excludes such a thesis.
But the primary expansion is the secondary one from the Balkans. As long ago Russian archaeologists put forward the thesis that the Thracian language spread in the early Iron Age through the succession of cultures Pšeničevo, Babadag, Basarabi, with which V13 already has direct connections. These cultures replace the previous cultures of the area with only partial assimilation, but generally have no continuity.
So this study contains, in addition to a bunch of samples with high WHG genetics, where there are already published ones, and another surprise: an almost completely autosomal farming population from the middle BD.
