A 200,000-year-old southern African population, linked to modern San people, shows deep genetic roots and unique adaptations, reshaping understanding of human origins.
A new study of ancient DNA from 28 individuals in southern Africa reveals a population that lived in near isolation for up to 200,000 years, developing a unique genetic profile with half of all known human genetic variation.
Found in modern San people, these ancient genomes show adaptations to harsh environments, including protection from sunlight, and reveal genetic variants not seen in other human groups.
The findings, published in Nature, challenge previous theories of human origins, positioning southern Africa as a key region in human evolution and highlighting long-term genetic continuity despite later contact with northern farmers.
