North Caucasus). <br /><br />It is interesting however to see in this PCA that there is a gap between West Asia & Caucasus and Europeans, even those that, like Romanians or Italians, show a clear tendency towards the Eastern vortex. It rings obvious that this gap is to be filled by Turks and Greeks (not plotted) but still it is quite notable when, by comparison, French, Hungarians and peoples of the Baltic area are comparatively so close (in spite of a similar geographic distance). <br /><br />This is probably because these three populations should have a single common origin majorly in Late UP/Epipaleolithic Europe, which continuously shows up as a shared "North European" indistinct component, from the Atlantic to parts of Russia, which is quite stubborn and hard to split. This is the same as the component you call "Lithuanian" elsewhere (its true origin is probably at the Rhine-Danube Paleolithic province, from Belgium to Hungary, but whatever). <br /><br />However you also managed to spot, thanks to the Chuvash sample, a further NE European (maybe Siberian or Central Asian ultimately) component. This is interesting because it further stretches the Baltic/Fenoscandian group in that direction and seems to say something about East European peculiarities.
