Five ancient genomes from Marcita (dated within 1400–900 BCE) provide a rare biological window into a Late Bronze Age Sicilian community. Among these samples, two male individuals carried Y-chromosome haplogroup G, while mitochondrial haplogroups were dominated by K (three individuals), with single occurrences of H and T. These results must be read cautiously: with only five genomes, statistical power is limited and broader population patterns cannot be confidently inferred.
Haplogroup G in Italy can reflect a deep substratum associated in some regions with Neolithic farmer lineages and later local persistence; however, G has diverse sublineages whose geographic histories vary, and we do not have enough samples to resolve subclade patterns at Marcita. The maternal signal — K (3/5), H (1/5), T (1/5) — aligns with distributions seen across Neolithic and Bronze Age Europe, where K and H are common among agriculturalist-descended populations and T appears episodically during the Bronze Age. Together, the genetic picture suggests substantial continuity with earlier European farmer ancestry, plus admixture from wider Mediterranean gene pools.
Genetic data here dovetails with archaeology: material evidence of interaction and modest mobility fits a community that maintained local roots while engaging in maritime exchange. Still, given the low sample count (<10), these genetic impressions are preliminary; larger, geographically broader sampling is required to test hypotheses about migration, continuity, and contact in Late Bronze Age Sicily.
