What an incredible new bottleneck I2 branch with 292 separate SNPs is this?! The legendary odd I1 branch has 311 SNPs.

This new branch so far has just two testees and is located at the Balkans. There's no age estimate yet but I'd guess the split-off will be something like 20,000 years ago.

FTDNA seems to have that bunch (see the red frame) more detailed, but still with very few testees. The two Balkanites at YFull seem to be beneath Y97843.

4 samples from Italy in this branch. Combined with the 2 Serbs on yfull, tracks well with the theory of WHG expanding out of refugia in Italy and southeastern Europe.

The imagination that such an lineage could have remained local since kind of 20,000 or 14,000 years is thrilling.

I know this is somewhat off topic, but I've always been interested in another rare I2 branch, I2-P37>M423>FGC41353>Y24694 (https://www.yfull.com/tree/I-Y24694/), which split from the rest of FGC41353+ samples around 14,200 years ago, has a very shallow TMRCA of only 2,500 years ago, and is mostly found in men of Iberian ancestry.

It really would be incredible. Especially for the Balkan region, which has been at the crossroads of population movements for 10000 years+. Someone wrote this on the Yfull FB group:


The two tested persons, one from Bosnia and Herzegovina and the other from Serbia, both share the mutation I-L415, which has been found in several skeletons from Lepenski Vir culture, so it is likely that this exotic male lineage in the Balkans passed through a "crazy long" genetic bottleneck from Neolithic period until today

This is how it looks on FTDNA:

I have recently been thinking about it as well and am cautiously optimistic about that theory. Other than I2b the Italian HG samples being the most WHG drifted is also pointing in that direction.

Also Iberia probably, their HG ancestry looks to be mostly native
