Genetics
The original Nuraghe inhabitants of Sardinia, who are now concentrated in the interior of the island due to pressure from colonists, are a genetic anomaly[citation needed] in the region. They belong to Y-chromosome haplogroup I, which otherwise has high frequency only in Scandinavia and the Croatia-Bosnia area.
Furthermore, the I haplogroup of the indigenous Sardinians is of the I1b1b subtype, which is unique to the island. The I1b1b haplogroup also has a low distribution in and around the Pyrenees, indicating some migration of Sardinians to or from that area. The Sardinian subtype is more closely related to the Croatian-Bosnian subtype than to the Scandinavian subtype. Sardinia also has a relatively high distribution of Y-chromosome haplogroup G, stemming from people that migrated to Sardinia from Anatolia. The Y-chromosome haplogroup G also has a relatively high concentration in and around the Pyrenees, again indicating migration of Sardinians to or from that area.
