Overview
G-FT66792 is a lineage that underwent its major demographic expansion in the Mediterranean and European classical-to-medieval transition periods. The lineage’s deep genealogical roots lie in Anatolia, consistent with all M406 sublineages, but its historical amplification took place primarily in Europe. The population contexts likely involved Roman mobility, post-Roman regional consolidation and maritime traffic along the Adriatic and Tyrrhenian basins.
The signature of FT66792 is its connection to communities operating around coastal settlements, military sites and trade ports. As such, it represents a historical diffusion wave rather than a prehistoric dispersal.
Geographic distribution
Modern carriers appear most frequently in Italy, Croatia, Albania, Greece and the western Balkans. Smaller clusters appear in Spain, France and the British Isles. The lineage is rare in Anatolia and the Near East, suggesting that its European presence reflects westward movement rather than deep prehistoric distribution.
Ancient DNA
- Roman provincial burials in Italy and Dalmatia present paternal profiles compatible with FT66792 ancestry.
- Late antiquity Aegean individuals show upstream markers that precede FT66792’s internal split.
- Early medieval Balkan samples exhibit partial SNP overlap with the western Balkan branch of this lineage.
Phylogeny & subclades
FT66792 divides into an Italian-Adriatic cluster and a Balkan-Greek cluster, each with further internal microclades. Divergence estimates point to the late Roman and early medieval transition. Its structure aligns with maritime and military corridor movements.
- G-FT66792* Italian-Adriatic basal lineage
- G-FT66792a Balkan-Greek branch
- G-FT66792b western European microcluster
- rare British Isles offshoots
Notes & context
FT66792 adds to the atlas’s European historical expansion category by documenting another Anatolian-rooted lineage that underwent demographic growth during classical and medieval periods.
