Ancient Genomes Reveal Early Human-Neanderthal Interactions and Extinctions
New studies uncover genetic links between early humans and Neanderthals, highlighting a complex migration and extinction history in Eurasia.
- Researchers analyzed the genomes of 45,000-year-old skeletons from Germany and the Czech Republic, the oldest known Homo sapiens genomes in Europe.
- Findings indicate that early humans interbred with Neanderthals for approximately 7,000 years after migrating out of Africa around 50,000 years ago.
- The genetic legacy of this interbreeding remains in modern non-African populations, with about 1-3% of their DNA tracing back to Neanderthals.
- Populations like the Ranis-Zlatý-kůň group in Central Europe represent evolutionary dead ends, leaving no genetic contribution to present-day humans.
- The studies also suggest that interbreeding with Neanderthals provided genetic advantages, such as adaptations related to immunity and metabolism, aiding survival in new environments.
