Ancient genomes reveal where migrants arrived from and when they adapted to high altitudes Modern inhabitants of the Tibetan Plateau are descendants of people who have occupied the ‘roof of the world’ for the past five millennia. In the biggest study of its kind, researchers sequenced dozens of ancient genomes from the region, revealing where its ancient settlers came from and how they adapted to high-altitude living.
