North east Italians did have high Balkan scores. That HGDP Tuscan sample is closer to Rome than it is to Firenze.
    From what I understand PCA based on correlation may "be more informative and reveals some structure in the data and relationships between variables", I'm quoting the exact words of an expert user on PCA. So maybe this PCA may reveal indeed a Balkan influence which differentiates the two Tuscan samples.

    I do agree with that you Northwest Italians are those who have less Balkan influence, which instead exists in the Northeast Italians.

Mainland Greece + Tuscany (+ Albania) vs the Aegean and South Italy/Sicily. It's probably due to greater later steppe ancestry in the former and greater near eastern ancestry in the latter added to the Neolithic base.
    But why is that central Italy is closer to Greece and Albania than let's say Anatolia?

    Is that supposed to be a serious question?

    It is.
    -- Here is one map showing Greece closer to Anatolia (Turkey/TR) than Italy. So it depends on the composition and calculation.

    That PCA is pretty old and doesn't seem to use good, representative sampling overall. Check out more recent stuff. You don't get a great reception because people are unsure whether you've just not kept up with this stuff at all or are just trawling, I think. :)

    The map your referencing has Greeks overlapping with Italians (not sure of the region), Albanians, Bulgarians but honestly it just looks really scrambled.
