The two first ones [J1b1a, J2a1a] have been considered as signals of major expansions occurring from the Near East towards Europe in the Late Glacial period [~16-12 kya]. The latter [i.e. J2b1a] is thought to be indeed an almost exclusive mtDNA marker of Europeans [33].Our data ...
As a reference, we applied the same analysis to the whole of R1b-S116, as well as to other common haplogroups such as G2a, I2, and J2a. Interestingly, all four haplogroups showed clear evidence of an expansion (p > 0.99 in all cases), all of them starting at the same time,...
