Theory Briefing
- Neanderthal DNA persists in modern non-African humans at roughly 1-4%, a fingerprint of ancient interbreeding events Reich's lab decoded.
- Reich's population genetics framework shows gene flow between archaic and modern humans was not a one-time event but a complex, multi-directional exchange.
- Some inherited Neanderthal variants affect immunity and disease risk today, proving ancient admixture has real consequences for living humans.
