first of all, maps need choice among the diverse poolings proposed - that said at first sight, I prefer the distribution maps of Eurogenes (16?) to the one based upon Dodecad (K12-b?) -Eurogenes shows well enough a western (Iberia-Sardigna) and an eastern 'mediterranean' group (this one corresponding in some part to SW-Asian + a part of 'mediterranean-near-easterners') and shows an atlantic group with Basques as leaders, well distinguished from 'west-mediterranean' and 'north-west-european', what I was waiting for a long time, according to physical anthropology and History -I suppose the atlantic element reflects in some way an old HGs heritage when the northern and southern other East Europeans are/were "newcomers" (by two different ways, I could bet)
just my present day thought
