Overview
G2a2b1a36 is a lineage representing the late antique to early medieval transfer of Anatolian rooted paternal ancestry into European populations connected through Roman administrative networks, trade corridors and later post Roman regional consolidation. While its ancestral layer belongs to the M406 radiation centered on Anatolia, the tmrca indicates historical era events that dispersed this lineage into diverse European settings. In the atlas, the branch illustrates how relatively small male lineages of eastern Mediterranean origin were absorbed into evolving European socio political environments without achieving major frequencies. Its profile exemplifies subtle but meaningful gene flow during the transitional centuries spanning the collapse of Roman order and the emergence of medieval polities.
Geographic distribution
Carriers of this lineage are generally found in Italy, Austria, Slovenia, Croatia, Hungary and southern Germany. Minor representation exists in France and the Low Countries. The distribution suggests integration along the Danubian basin, northern Italian plains and the central European frontier of the Roman world. Scarce occurrences in Anatolia and the Levant reflect its original source but not its main demographic expansion zone.
Ancient DNA
- Late Roman burials in northern Italy and the Alpine foothills show upstream markers characteristic of early G-M406 derived lines.
- Early medieval central European graves present partial genetic overlap with FT82047 structuring, especially in regions close to former Roman garrisons.
- Archaeogenetic signals from late antique sites on the Adriatic show possible links to ancestral components of this clade.
Phylogeny & subclades
FT82047 divides into an Alpine–Danubian branch and a western-central European branch. A third, smaller Adriatic derivative is recognized as a microclade. Divergence times fall into the late Roman to early medieval range, matching known episodes of demographic restructuring driven by military redeployments, trade shifts and post imperial population mixing.
- G-FT82047* Alpine–Danubian basal lineage
- G-FT82047a central and western European branch
- G-FT82047b Adriatic coastal microbranch
- G-FT82047c rare northern Italian derivative
Notes & context
This lineage provides essential representation for the subtle historical movement of eastern Mediterranean G2a lineages into the heart of Europe through administrative, military and economic channels of the late Roman world.
