Overview
R-FGC22501 is a rare downstream lineage under R-U152 that likely emerged during the late Bronze Age within populations inhabiting the Alpine foothills and upper Rhine regions. Archaeological evidence from this period shows intensified metalworking, the development of fortified communities and increased trade connectivity linking central Europe to northern Italy and the western European plains. FGC22501 probably originated among small kin groups living within these zones.
During the Iron Age, FGC22501 lineages participated in the cultural developments associated with Hallstatt and La Tene societies. These groups maintained longstanding trade routes, including salt roads, metal exchange networks and Alpine crossings. The lineage's rarity reflects microregional persistence rather than large scale expansion. Under Roman rule, FGC22501 individuals were integrated into provincial contexts, including military activity near the Rhine frontier. Through the medieval period, the lineage persisted in Alpine and upper Rhine communities shaped by Alemannic, Bavarian and local identities.
Geographic distribution
R-FGC22501 appears mainly in Switzerland, southwest Germany and eastern France. Additional occurrences in Austria and northern Italy reflect deep historical connections across Alpine corridors. It is rare in Belgium, the Netherlands or the British Isles. Outside Europe, the lineage appears in diaspora populations with roots in these central European regions.
Ancient DNA
- La Tene individuals from the Swiss plateau exhibit R1b-P312 lineages compatible with FGC22501.
- Hallstatt burials in the Alpine forelands include haplotypes that modern analyses place near FGC22501.
- Roman era skeletons in upper Raetia contain U152 derived chromosomes aligned with ancestral FGC22501.
- Early medieval Alemannic graves exhibit haplotypes consistent with FGC22501 preservation.
- Iron Age individuals from the upper Rhine display signatures overlapping with the FGC22501 phylogenetic zone.
- Comparative studies show long term U152 continuity including minor branches such as FGC22501.
Phylogeny & subclades
R-FGC22501 forms a very small but clearly structured branch under U152. Its internal topology includes a few microclusters, each tied closely to Alpine or upper Rhine localities. The lineage likely maintained small but stable populations throughout its history, giving it strong regional character.
- Swiss microclusters
- Southern German variants
- Alpine foothill branches
Notes & context
R-FGC22501 is a key lineage for extremely fine scale paternal ancestry in central Europe. Although rare, its presence strongly indicates ancestry from historically stable Alpine populations. It contributes to completing the full phylogenetic landscape of U152, ensuring that minor but meaningful lineages are represented in a comprehensive atlas.
