Arslantepe: Late Chalcolithic Echoes

Rising from the silts of the upper Euphrates, Arslantepe is a long-occupied tell whose Late Chalcolithic horizon (c. 3946–3032 BCE) registers increased social complexity across eastern Anatolia. Archaeological data indicates monumental architecture, specialized craft production, and exchange networks that linked the highlands with Mesopotamia and the Aegean margin. Stratigraphic sequences at Arslantepe show phases of rebuilding and fortification, suggesting episodes of competition or external threat.

The genetic signal from 18 individuals sampled at Arslantepe complements the material record. Y-chromosome lineages dominated by haplogroups J and G point toward continuity with broader Near Eastern male ancestry clusters known from contemporaneous Anatolian and Levantine sites. Maternal haplogroups (K, H, J1c, N, X) reveal a mosaic of West Eurasian lineages, reflecting both local continuity and long-range connections. Limited evidence cautions against sweeping narratives: while patterns fit a Near Eastern core with punctuated input, the resolution of demographic events (migration, marriage networks, or elite exchange) remains provisional pending larger comparative datasets.

Arslantepe's emergence should therefore be read as a palimpsest — built of local traditions, regional ties, and episodes of external influence visible in both objects and genomes.

Eighteen genomes from Arslantepe_LateC offer a moderately sized window into Late Chalcolithic population structure. Y-DNA is dominated by haplogroups J (5/18) and G (4/18), lineages frequently associated with long-standing Near Eastern male ancestries in Anatolia and the Levant. Smaller counts of H (2), E (1) and R (1) indicate some heterogeneity: haplogroup H—while more common in South Asia—appears sporadically in West Eurasian contexts and may reflect low-level gene flow or ancestrally diverse paternal lines.

Mitochondrial diversity is notable: K (3), H (2), J1c (2), N (2), and X (2) together suggest a wide array of maternal origins with strong ties to West Eurasia. Maternal haplogroups such as K and H are common across prehistoric Europe and the Near East, while J1c and X point to lineages with deep regional roots. Archaeogenetic analyses indicate that the Arslantepe community fits a Near Eastern cluster but with detectable internal diversity consistent with trade and interregional marriage.

Caveats: although 18 samples provide better resolution than single graves, this is still a moderate sample size. Patterns observed are robust enough to suggest a Near Eastern genetic backbone with punctuated external inputs, but demographic processes (directionality of gene flow, kinship structures, social transmission) require more samples and ancient DNA from neighboring sites for definitive models.
