San Teodoro Epigravettian of Sicily

The Epigravettian occupants of San Teodoro emerged against the dramatic backdrop of a warming post-glacial world. Dated human remains and associated deposits from San Teodoro cave near Messina place people on northeastern Sicily between roughly 17,171 and 11,397 BCE. Archaeological data indicates adaptation to shifting coastlines and rich marine resources as sea levels rose after the Last Glacial Maximum. Lithic typologies attributed to the Epigravettian tradition—backed blades, microliths, and retouched tools—tie Sicilian groups into a wider southern European cultural horizon.

Limited evidence suggests these groups were part of regional networks of mobility rather than isolated island populations: similarities in tool styles and raw-material procurement hint at contacts with mainland southern Italy and the central Mediterranean. Yet the island setting also fostered local innovations in subsistence and settlement. While evocative rock shelters and hearth features survive at San Teodoro, the sparse sample count and taphonomic loss over millennia mean our picture is fragmentary. Archaeology indicates a resilient human presence that negotiated dramatic environmental change, leaving a material signature that only begins to align with early genetic snapshots.

Three analyzed individuals from San Teodoro yield a clear maternal signal: all carry mitochondrial haplogroup U. Haplogroup U and its sublineages are common among Late Palaeolithic and Mesolithic hunter-gatherers across Europe, suggesting that the maternal lineages in Sicily fit within a broader continental pattern of post-glacial recolonization by hunter-gatherer populations. No consistent Y-chromosome haplogroup is reported for these samples, so paternal affinities remain unresolved.

Genetic data from these three individuals provide tantalizing but preliminary insights. With only three genomes, any inference about population structure, continuity, or admixture must be cautious. Archaeogenetic studies elsewhere have shown that Late Palaeolithic European hunter-gatherers often share affinities with clusters sometimes called Western Hunter-Gatherers or Villabruna-related groups; limited evidence suggests Sicilian Epigravettians may have connections to these broader gene pools, but firm conclusions require larger sample sizes and comparative analyses. Future sampling could reveal whether San Teodoro individuals represent island-endemic lineages, mainland-derived migrants, or a mixture shaped by maritime mobility. For now, mitochondrial uniformity (U) is a clear signal, while the deeper demographic story remains an open and compelling question.
