Observation from all these years on Albanian discussions on fora: if people are overcomplicating stuff, they are almost definitely wrong about it. Sardinian origin of J2b2, "Daco-Thracian" (lol) E-V13, Asian Komani culture. It's all in the same piece of paper that has it's place in the toilet.
What's laughable about Proto-Thracians being dominated by E-V13?
- The modern phylogeny and distribution of E-V13 demands a series of drastic founder effects in the transitional period (1.300-900 BC)
- In this period G?va/Channelled Ware expanded at the expanse of earlier groups in the whole Central and Eastern Balkan, down to Greece and Asia minor
- The following cultures, which are clearly Dacian and Thracian respectively, Bosut-Basarabi and Psenichevo, already showed E-V13 as the dominant haplogroup in the sites of Viminacium and Kapitan Andreevo respectively
- In most areas, especially those of Psenichevo-Basarabi, where Channelled Ware/G?va derived groups dominated in the Late Bronze Age, we see Daco-Thracian ethnicities later.
This is pretty straightforward and simple, and only overcomplicated for people which lack a basic understanding of the problem and requirements to solve it. Like any sort of failed solution with E-V13 just sitting around among the many other Early Bronze Age lineages, in the Balkans, is unable to explain the great cultural shift (no genetic effect at all?) and the radical expansion of E-V13 at that time. By connecting three aspects:
1) Channelled Ware/Psenichevo-Basarabi
2) E-V13 expansion in the transitional period (its there, just look at the tree)
3) The appearance of Daco-Thracian ethnicities in the areas affected by both
You get an elegant solution for an old problem.
By stating "E-V13 just hid somewhere in the Balkans", you don't solve any of this at all. There must have been a series of founder effects in just the right time, in the transitional period and the expansion wasn't going from the South to the North, at least not South of the Danube, that's for sure.
If people lack the basic understanding for the phylogeny of E-V13, the archaeological situation of the Balkans in the Late Bronze and Early Iron Age, as well as the ethnolinguistic divisions of the Iron Age period, they can't properly understand what this is about and it may appear for such people that the simplest possible solution is "overcomplicated".
Everyone can check the E-V13 tree on YFull and count how many of the main splits date back to the LBA-EIA transition:

For E-V13 the first big time for the diversification and expansion of its subclades was definitely right when Channelled Ware/South Eastern Urnfield conquered the Balkans. This is as obvious as the Bell Beaker spread in Iberia or Britain. The question is just whether they started right from the Upper Tisza (G?va core) or from a secondary centre at the Danube (Belegis II-G?va/Fluted Ware Bulgaria).
