Overview

J2a-FGC18155 is a downstream component of the J2a-Z2227 Mediterranean and coastal-oriented radiation. Its earliest diversification corresponds to the emergence of Holocene maritime communities along the southern Anatolian coastlines and the eastern Mediterranean islands. Archaeological correlations include Chalcolithic port settlements, early copper trade nodes and the maritime exchange systems that linked southwestern Anatolia, Cyprus and the Levant. During the Bronze Age, FGC18155-bearing groups were involved in the demographic processes tied to Cypriot and Anatolian metallurgy, Aegean–Levantine maritime corridors and proto-urban systems of the eastern Mediterranean. Its downstream structure includes several insular and littoral subbranches, indicating recurrent localized expansions followed by long term demographic continuity through Classical and Hellenistic periods.

Geographic distribution

Cyprus, southwestern Turkey, Dodecanese, Crete, southern Levant; minor presence in Greece and southern Italy.

Ancient DNA

  • Bronze Age Cyprus populations show upstream J2a signals consistent with ancestral FGC18155.
  • Southern Anatolian Bronze Age individuals exhibit J2a-Z2227 diversity related to this clade.
  • Aegean Bronze Age samples carry J2a lineages connected to maritime expansions parallel to this cluster.
  • Classical port towns of the eastern Mediterranean preserve downstream derivatives.
  • Roman insular populations show persistence of FGC18155 microbranches.
