Funnily enough, despite being more Balkan-shifted, the average of those three corners actually captures fewer Turks than using Austria as the center. Fair point though: you picked a concrete, existing population. Mine is an abstract geodesic centroid. Still, I'd go with Basque_Labourd as the european-most. And Romanian_Transylvania as core European, controversial as it may sound.😆
I'd disagree on that in the sense that Europe is more ethno-political than a landmass division. I can't speak for Greek Cypriots, of course. I'm just using them as a modern proxy for an archaic population that I consider fundamental to what we understand as Europe today. Also, the average of those three triangle corners doesn't fall that far from Austrians, look (no sims):
An arbitrary cutoff, but not a meaningless one. Plot European populations on a PCA and they form a near-perfect triangle: Basques, Greek Cypriots, and Latvians at the three corners. Latvians are the closest people alive to WHGs, Greek Cypriots carry the ancestry of the civilizations that built the classical world. And Basques occupy the vertex furthest from everything else simultaneously
