Briefings

An international consortium led by IBE, Harvard, and EHU reconstructed the genetic history of Iberia between the first and eighth centuries A.D. by analyzing 243 ancient genomes from 31 archaeological sites. The study reveals that despite significant migrations by Suebi, Alans, and Visigoths, the deep genetic legacy of Roman Hispania persisted, with ancient populations maintaining substantial genetic continuity into the medieval period.

Key points

• The study reconstructed the genetic history of Iberia using 243 ancient genomes from 31 archaeological sites.
• Ancient populations maintained substantial genetic continuity into the medieval period despite major migrations.

Context

This research addresses the long-standing debate about whether early medieval migrations erased the genetic legacy of Roman Hispania, providing a comprehensive genetic timeline for the Iberian Peninsula.

Limitations

The analysis relies on 243 ancient genomes from 31 archaeological sites, limiting the scope to specific locations and time periods. Results are based on preprint data and require further validation.
