Maciamo what do you think about this table I've made:
Most Greco-Neolithic countries in Europe (E1b1b + J2 + G2a):
1. Greece: around 51%
2. Albania: around 48%
3. Bulgaria: around 45%
4. Rep. Macedonia: around 41%
5. Italy: around 37%
6. Romania & Austria: around 30%
7. Portugal: around 29%
8. Serbia: around 27%
9. Hungary: around 25%
10. Bosnia: around 22%
I suppose you have made the total of (E1b1b + J2 + G2a based on my Y-DNA frequency table. The only problem is that we still don't know for sure that all E1b1b and J2 are or Neolithic origin. Most of the European E1b1b could be Paleolithic/Mesolithic or Neolthic or both. But some could even be more recent than that. As for J2, I think that it could have come partly during Neolithic, but mostly during the Bronze Age and Iron Age (or at least expanded from Greece and Anatolia during that period). I also think that a lot of European J1 and T could be Neolithic.
