Now results show clear western and eastern clines in Europe. I have no sure explanations why this happens, but perhaps the western cline proves about Megalithic and Bell Beaker elements and the eastern one more about the Bronze Age intrusion of people from East European plain.
Eastern Finnic groups carry bidirectional history, which is seen on dimensions 2 and 3. It is really pity that we still have to wait for academic Saami samples. We need those samples to prove possible eastern Saami connection which can be rather old considering the large area of this bidirectional result continuing from Eastern White Sea region to Finland. But we need Saami samples to prove it.
Eigenvalue for the eigenvector 1 is 2.286778, for the second one 1.353679 and for the third one 1.339063, so dimensions 2 and 3 on plots represent almost equal dependences between samples. You can also make a live 3d-view using applicable software by downloading 3d-data here.
