Voices of the Levant: Israel_MLBA

Under a sky of cedar scent and coastal winds, the Middle to Late Bronze Age communities sampled here coalesced into dense towns and fortified sites across the Jezreel Valley and coastal corridors. Archaeological data indicates settlement continuity and expansion between major tells—Megiddo and Hazor—and smaller nodes such as Tel Shadud, Yehud and Baq'ah in Jordan. Material culture—standardized ceramics, storage architecture and monumental fortifications—speaks to administrative complexity and integration into eastern Mediterranean trade networks during the second millennium BCE.

Genetic sampling of 52 individuals dated ca. 2010–1100 BCE anchors these archaeological patterns to people. A strong representation of Y‑chromosome haplogroup J aligns with a long‑standing Near Eastern paternal landscape. Yet the presence of R, E and CT paternal lineages hints at additional inputs or localized heterogeneity. Mitochondrial diversity (T, N, U, H, J) suggests varied maternal ancestries, consistent with the Levant’s role as a crossroads.

Limited spatial sampling still leaves open questions about population structure across the southern Levant. While the combined archaeological and genetic picture sketches communities embedded in regional trade and political networks, the precise directions and timing of gene flow—whether gradual local admixture or episodic arrivals—remain partly unresolved.

The genetic portrait from 52 individuals provides a substantive snapshot of male and female lineages in the southern Levant during the Middle–Late Bronze Age. On the paternal side, haplogroup J is predominant (22 of 52), consistent with long‑established Near Eastern male lineages. J2a appears among these data (2 counts), a clade commonly associated with Neolithic and Bronze Age Near Eastern contexts. The presence of R (4) and CT (2) indicates additional paternal diversity; these lineages may reflect gene flow from regions beyond the Levant or internal demographic complexity, but without deeper subclade or autosomal resolution their precise origins remain uncertain.

Mitochondrial diversity is notable: the most frequent maternal groups are T and N (each 5), followed by U, H and J. This mix suggests maternal ancestries spanning familiar Near Eastern and Mediterranean haplogroups, compatible with a region shaped by mobility and exchange. The sample size (n=52) affords reasonable confidence in observed haplogroup frequencies for these sites, yet geographic sampling is concentrated in a few tells. Consequently, conclusions about wider Levantine population structure should be cautious.

Archaeogenetic integration with archaeological contexts reveals patterns of continuity alongside heterogeneity: a broadly Near Eastern gene pool with punctuated inputs. Future high‑coverage autosomal sequencing and broader spatial sampling will be crucial to resolve admixture timing, kinship within cemeteries, and sex‑biased mobility.
