Two significant studies were Semino 2000 and Rosser 2000, which identified haplogroups J2 and E1b1b (formerly E3b) as the putative genetic signatures of migrating Neolithic farmers from Anatolia, and therefore represent the Y-chromosomal components of a Neolithic demic diffusion.
Two significant studies were Semino 2000 and Rosser 2000, which identified haplogroups J2 and E1b1b (formerly E3b) as the putative genetic signatures of migrating Neolithic farmers from Anatolia, Rosser et al. NB Here, Rosser uses the nomenclature HG 1 for R1b, and HG 9 for J2 and therefore represent the Y-chromosomal components of a Neolithic demic diffusion.
