Overview
J2b-Z40194 is a downstream component of the J2b-M241 radiation with a strong demographic presence in the southern Balkans, Aegean basin and western Anatolia. Its earliest development corresponds to mid Holocene agro pastoral expansions through the Balkan interior, followed by increasing coastal integration during the Chalcolithic and Bronze Age periods. Archaeological parallels include late Neolithic Balkan village networks, Aegean island communities and proto urban western Anatolian coastal sites.
During the Bronze Age, Z40194 bearing groups were connected to Mycenaean mobility patterns, Aegean maritime corridors and population exchanges between the Adriatic, Greece and Anatolia. Its downstream diversity suggests multiple founder effects in coastal and island populations with sustained presence through the Iron Age and classical periods.
Geographic distribution
Most common in Greece, Albania and western Turkey; moderate in North Macedonia, Cyprus and Bulgaria; lower in Italy and the Levant.
Ancient DNA
- Neolithic Balkan individuals show ancestral J2b structures related to early Z40194.
- Aegean Bronze Age burials include upstream J2b lineages mapping to this branch.
- Western Anatolian Bronze Age remains contain paternal markers consistent with Z40194.
- Iron Age Levantine individuals exhibit downstream signals of this lineage.
- Classical Greek sites maintain strong continuity with Z40194 derived clusters.
