Five ancient individuals from Himera provide an initial genetic window into Classical Sicilian life. Maternal lineages are dominated by mtDNA H (3/5), with single occurrences of mtDNA J and T. MtDNA H is widespread in Europe and the Mediterranean and its presence here aligns with broad maternal continuity across southern Italy. Haplogroups J and T are also common in the Near East and Mediterranean, compatible with historical models of east–west connectivity.
On the paternal side, two individuals carry Y-haplogroup R (a cluster common across much of Europe), while one carries haplogroup L. Y-L (L-M20 and related branches) has higher frequencies in South Asia and parts of western Asia and is uncommon as an autochthonous marker in central Mediterranean contexts; in this small dataset it could reflect an individual-level connection—trade, migration, or later admixture—or sampling noise. No claim is made about broad population replacement or major migrations from this evidence alone.
Because the dataset totals five samples, statistical power is low. Archaeogenetic interpretation must therefore remain cautious: the patterns are consistent with a predominantly European maternal heritage and a paternal pool reflecting both local European and less typical lineages. These data hint at sex-biased gene flow possibilities (for example, incoming male lineages in a multilingual port city), but further sampling across tombs, households and temporal horizons is needed to test such hypotheses.
Methodological caveats: preservation bias, burial selection, and low sample counts can distort apparent frequencies; contamination and differential sequencing coverage can affect Y-chromosome calls. Consequently, the Himera genetic portrait should be viewed as a promising preliminary snapshot that invites expanded sampling and comparative analysis with neighboring Sicilian, Greek and Punic datasets.
