I'm reposting this from something I put in the E-V13 related threads:
There's now confirmed E1b1b1a1(2) in Neolithic Europe, so that part of the debate is over. There's also J2.
Ed. Sorry, I didn't add that one is M78, and one may already be E-V13.
The cultures are Lengyel and Sopot.The date is 4780-4700 BC.
The rest are G2a, F*, I2a1, J2, and C.
R1b and I2a2 don't show up until the Bronze Age.
The J2 was from 4990-4850 BC. One was found in Lengyel and one in Sopot culture.
I'd love to say that it was late Neolithic because then I'd have come in under the wire by saying J2 could have come in during the Late Neolithic, but I've seen Lengyel described as a middle/late Neolithic culture. Kudos to Maciamo and LeBrok for holding out for a Neolithic entry of J2 into Europe.
This puts that Bronze Age J2 and what seemed like his anomalous appearance in perspective. So much for he wandered up from Bronze Age Anatolia via the Aegean. The J2 could have been present there in Europe all along.
There is also yDna "C" of uncertain origin...
The question remaining is were J2 and E-M78, for example, present in the earliest Neolithic in the southern most regions of Europe, and just didn't move north until later, or were they a slightly different Neolithic population that entered even southern Europe slightly later than G2a?
This is what the author has to say:
"The three new NRY, J, C, and Eb1b1a signalize new population elements in the Sopot community, which subsisted during and after the Lengyel period of the region as well."
"It's difficult to define the origin of these new components..."
"The question is, why this group cannot be seen in the Early Neolithic of Transdanubia? Had it been there and remained undetected by chance? Alternatively, did J arrive with the first farmers and halted in southern Europe for a while (~1000 years) from where it dispersed in the Sopot period?"
