Overview
E-BY154477 is a minor but phylogenetically informative sub-branch of E-Z25374. The lineage’s time to most recent common ancestor falls in the Middle to Late Bronze Age, suggesting that its early carriers were part of the highly dynamic populations of the Northern Levant and southern Anatolia. Although the clade is not numerous today, its structure indicates a small but persistent population that underwent limited regional dispersal rather than large-scale demographic expansion. E-BY154477 helps clarify the intermediate layers of E1b1b1 diversification that occurred as agro-pastoralist groups spread and settled through the Eastern Mediterranean corridor.
Geographic distribution
Modern carriers of E-BY154477 show their highest concentrations in the Levant (particularly Lebanon and northern Israel), as well as in southern Anatolia. A smaller number of occurrences appear in Cyprus, Crete, and coastal western Turkey, likely reflecting historical maritime traffic and cultural exchange networks of the Bronze and Iron Age eastern Mediterranean. Rare outlier samples in the Balkans and Italy are typically consistent with later secondary diffusion.
Ancient DNA
- No confirmed ancient individual assigned directly to E-BY154477, but surrounding branches within the parent cluster appear in ancient Levantine and Anatolian datasets.
- The estimated age and phylogenetic position align with Eastern Mediterranean populations active during the Bronze Age trade sphere.
Phylogeny & subclades
Notes & context
E-BY154477 exhibits a branching pattern consistent with a lineage that experienced regional stability rather than explosive expansion. It is valuable for reconstructing fine-scale movements between southern Anatolia and the northern Levant. Its subclades, while not numerous, likely formed through localized founder effects during the Bronze to early Iron Age transition.
