Dude, all Southern Caucasians have overlapping genetic components just like you Balkanites do, and the reason being is that they all essentially derive ancestries from Kura-Araxes, Maikop and other groups in the area. I told you Pontics are Myceneans + local Colchis, do you know who ancient Colchians were? Do you know why Greeks went there? Are you familiar with the importance of the area in the ancient Greek world, the myth of Jason and the Argonauts and the ancient tragedy of Medea by Euripides?
Do you have an ancient Colchis sample? No? Neither do I, that's why I use other proxies in the geographical area, like Georgians, Armenians, Maikop, Kura-araxes, etc.
And they all pass showing 60-70% "native" South Caucasus and 30-40% Mycenean.
And you bring me those laughable PCAs as an answer in order to tell me it's barely 10-15%, when I provide you with proof it's not. And, by the way, since you use 25 dimensions in your PCA, flip the dimensions and show us how the PCA looks like from other "angles", ie using other dimensions in the X and Y axis, not just the one that suits your little fairytale.
You Albanian guys are something else, proclaimed experts on all things ancient Greek, too bad it's all BS.
