The Eastern side of the Westernmost Europeans: Insights from subclades within Y ‐chromosome haplogroup J‐M304

ConclusionsWhile previous inferences based on modern haplogroup J Y‐chromosomes implicated a main Neolithic dissemination, here we propose a later arrival of J lineages into Iberia using a combination of novel Portuguese Y‐chromosomal data and recent evidence from ancient DNA. Our analysis suggests that a substantial tranche of J1‐M267 lineages was likely carried into the Iberian Peninsula as a consequence of the trans‐Mediterranean contacts during the first millennium BC, while most of the J2‐M172 lineages may be associated with post‐Neolithic population movements within Europe.
