Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~20,000 and 12,000 years ago, with the virus present in European and South American hunter-gatherers during the early Holocene.

- The Iberian Peninsula served as a key area for studying human population movements during prehistoric times, particularly during the Last Glacial Maximum (LGM), acting as a refuge for hunter-gatherers who later contributed to the repopulation of northern areas.
- Recent research revealed that the genetic makeup of Iberian hunter-gatherers (HGs) includes ancestral ties to both the Villabruna individual from Italy and Magdalenian-related groups, indicating a complex ancestry in the region.
- New genomic data from Iberian Early and Middle Neolithic individuals support the idea that as farming expanded into the region, there was significant mixing with the local hunter-gatherer populations, preserving the dual genetic legacy.
Article Synopsis
- Agriculture arrived in the Iberian Peninsula around 5700 BCE, marking a shift in lifestyle from hunter-gatherers to farming communities.
- This study analyzes the mitochondrial DNA of 213 individuals across various regions of Iberia from the Neolithic to the Early Bronze Age, contributing to a comprehensive understanding of prehistoric populations.
- The findings indicate a notable genetic continuity in the Early Neolithic lineages, with a higher presence of hunter-gatherer genes in Iberia compared to other parts of Europe, suggesting a unique population history for the region.
