Overview
J2b-Y15058 is a downstream branch of J2b-M241 with a distribution that bridges the Balkans, western Anatolia and the eastern Mediterranean. Its age points to an origin in early Holocene populations that were part of the same broad Neolithic interaction sphere linking the Aegean, western Anatolia and the central Balkans. By the Bronze Age, Y15058-bearing lineages were embedded in societies associated with complex chiefdoms and early states in the Balkans and Aegean region, and they likely contributed to the paternal ancestry of later Greek, Illyrian and Thracian cultural formations. The clade also appears in Levantine and Anatolian populations, indicating sustained gene flow along maritime and overland routes connecting southeastern Europe and Southwest Asia.
Geographic distribution
Today, J2b-Y15058 is most frequently observed in the western and central Balkans (Albania, Kosovo, North Macedonia, Montenegro, parts of Greece and Bulgaria), as well as in coastal western Anatolia, some Aegean islands and sporadically in southern Italy. Lower but notable frequencies occur in the Levant and Cyprus, reflecting historical eastern Mediterranean connectivity. Occasional occurrences in Central Europe and the Caucasus are generally interpreted as the result of secondary dispersals rather than primary centers of diversity. The clade’s distribution broadly tracks regions that were strongly impacted by Neolithic farming expansions from the Aegean, as well as by later Bronze Age and classical movements in the Balkans and eastern Mediterranean.
Ancient DNA
- Neolithic and Chalcolithic individuals from the Balkans carry J2b lineages that may include early precursors to Y15058.
- Bronze Age archaeological contexts in Greece, Albania and the central Balkans reveal J2b-M241-related haplotypes compatible with Y15058 diversification.
- Aegean Bronze Age individuals with Balkan connections show J2b variants that could derive from Y15058-bearing populations.
- Iron Age and classical-era remains from the western Balkans and Greece show continuity of J2b branches in urban and tribal settings.
- Levantine coastal and Anatolian individuals from the Bronze and Iron Ages occasionally show J2b lineages that fit within the broader Y15058 phylogenetic framework.
Phylogeny & subclades
J2b-Y15058 forms a structured set of branches under J2b-M241, with clear clustering in the Balkans and adjacent regions. Sub-branches show evidence of local founder effects in specific mountain valleys and coastal zones, consistent with the historical pattern of small tribal units, village endogamy and geographically constrained expansions. Some downstream lineages extend into the eastern Mediterranean and western Anatolia, matching maritime connectivity patterns during the Bronze Age and later periods.
- Y15058* (basal, low frequency)
- Balkan-centered microclades in Albania, Kosovo and northern Greece
- Aegean and western Anatolian sub-branches
- Low-frequency Levantine and Italian clusters
Notes & context
J2b-Y15058 illustrates how J2b lineages became deeply embedded within southeastern European population history while maintaining genetic links to Southwest Asia. The clade’s structure and geography indicate that Neolithic and Bronze Age movements were followed by strong local drift and founder effects. It should not be simplistically equated with any single historic group such as “Illyrians” or “Greeks,” but rather viewed as part of a broader Balkan–Aegean–Anatolian genetic continuum.
