Sardinia: Middle Bronze Age Echoes

Beneath wind-swept maquis and the silhouette of limestone ridges, Middle Bronze Age Sardinia (1800–1234 BCE) stands as an island chapter written in stone and bone. Archaeological contexts tied to Anghelu Ruju and Seulo yield a fragile window into this era: funerary deposits, reused ritual spaces, and settlement traces that suggest communities negotiating long-term Mediterranean networks. The islands’ long Neolithic legacy — visible in pottery traditions and megalithic architecture — frames the Middle Bronze Age as both continuity and change.

Limited evidence suggests that local traditions persisted while new material influences reached the coast and interior. Radiocarbon-dated contexts place these samples squarely within the Middle Bronze Age horizon, but stratigraphic mixing and later use of ancient sites complicate a simple narrative. Archaeological data indicate that Sardinian communities maintained island-specific lifeways while participating in broader Bronze Age exchange across the central Mediterranean.

Because only four individuals are available, any model of population emergence must remain tentative. These remains are best seen as pieces of a larger, still incomplete puzzle: they hint at enduring local roots layered with incoming influences from maritime contacts, rather than wholesale population replacement.

Ancient DNA from four Middle Bronze Age individuals on Sardinia produces a cautious but evocative genetic portrait. Paternal lineages include haplogroups I (two individuals) and G (one individual reported); mtDNA haplogroups include J (two), H (one), and T (one). These signals are consistent with a mosaic of deep European hunter-gatherer heritage (often linked to Y-haplogroup I) and enduring Neolithic farmer-related ancestry (Y-haplogroup G and mtDNA lineages like J and T).

Archaeogenetic research across Sardinia and the central Mediterranean has repeatedly shown that the island retained a high proportion of early farmer ancestry relative to many continental populations. The presence of mtDNA lineages J, H, and T in these MBA individuals aligns with that broader pattern. However, with only four samples, statistical power is low: observed haplogroups may reflect local family structure or burial selection rather than island-wide frequencies.

Limited evidence suggests continuity from Neolithic to Bronze Age populations on Sardinia, punctuated by gene flow events of varying intensity across centuries. These four genomes contribute to a growing dataset that, when combined with additional samples, will refine models of continuity, admixture, and the demographic impact of Bronze Age maritime connections.
