Recent ancient DNA research provides the first comprehensive view of the Picenes (Picentes), an Iron Age population of Central Italy along the Middle Adriatic coast. This study sheds light on their paternal lineages, ancestral composition, and genetic relationships with neighboring populations.
Paternal Lineages#
Analysis of Picene male individuals identifies two main Y-chromosome haplogroups. R1b‑M269 / L23 is the dominant lineage, linked to Steppe-related ancestry and widespread across Bronze Age and Iron Age Europe. Subclades suggest connections to both Central and Western European populations. J2‑M172 / M12, including subclades like J2b‑L283, indicates links with Western Balkan and Illyrian populations. These two haplogroups represent the documented Picene paternal diversity in the dataset; other lineages were not reported.
Ancestral Composition#
Genome-wide analysis reveals that the Picenes' ancestry derives from three primary components: Western Steppe Herders, Western Hunter Gatherers, and European Neolithic Farmers.
Admixture models indicate that the Picenes carry a high proportion of combined Yamnaya and Anatolian Neolithic ancestry, with minor contributions from WHG. Their profile is broadly consistent with other Iron Age Central Italian populations, while subtle shifts reflect regional specificity.
Regional Variation#
When modeled alongside Western Balkan, Northern, and local Italic proxies, the Picenes reveal subtle regional variation in their ancestry. Northern Picenes show stronger connections to Western Balkan and northern/Celtic-associated populations, reflecting greater influence from trans-Adriatic interactions, while southern Picenes appear more closely aligned with local Italic groups, suggesting stronger continuity within Central Italy. Across the region, all Picenes maintain a balance of external influences and local ancestry, placing them in an intermediate genetic position distinct from both Etruscans and fully northern populations.
Genetic Position in Iron Age Italy#
The genetic evidence positions the Picenes as a dynamic population within Iron Age Italy. They were neither fully aligned with northern/Celtic nor entirely with local Italic groups. Instead, they combined external influences from across the Adriatic with regional continuity, resulting in a distinct genetic signature. PCA and clustering analyses further confirm that Picenes occupy an intermediate space between Central European, Balkan, and Italian populations, with subtle north-south differences reflecting local demographic history.
