Genetic differentiation in S.Italy : new clusters and evidence from recent admixture from Greece

[Grace O'Malley]

Yes I used R1b-U152 because it's related to Italics, and a higher distribution in this area where Bruttians lived (Lucanians/Sicels and also additional Samnite tribes) is not surprising definitely.

Cosentia alone had loads of Italic people, and also in the countryside.

Yes I can understand that but the first map being labelled Italo-Celtic is not a very accurate description of R1b but I'm aware you didn't name it that. This is what I wanted to highlight.

The possible explanation for their 20.3% Greek ancestry is the presence of an ethnic Greek community in Calabria. The Greek settlements were founded in the region during the Classical period. The Ancient Greeks colonized southern Italy beginning in the 8th century BC and the region was called Magna Graecia.

I don't think that this percentage is reflecting ancient greek admixture but rather recent.

As I've said there have been recent movements from Greece to Southern Italy + if you add Arbereshe you can have easily results like that.
