WASHINGTON (AP) — Africans have more genetic variation than anyone else on Earth, according to a new study that helps narrow the location where humans first evolved, probably near the South ...

Humans were isolated in southern Africa for about 100,000 years, which caused them to "fall outside the range of genetic variation" seen in modern-day people, a new genetic study reveals. The finding ...

A new study provides fresh evidence that ancient interbreeding with archaic human species may have provided modern humans with genetic variation that helped them adapt to new environments as they ...

Scientists have discovered that a gene called MUC19, inherited from Denisovans through ancient interbreeding, may have played a vital role in helping Indigenous ancestors adapt as they migrated into ...

Genome assemblies from 65 individuals, representing a variety of the world’s populations, are advancing the scientific exploration of complex genetic structural variation. Structural variations are ...

Structural variants (SVs) are alterations in the DNA sequence that involve large-scale changes, typically longer than 50 base pairs. Advances in long-read sequencing have significantly increased ...

The Indigenous peoples of the Bolivian highlands are survivors. For thousands of years they have lived at altitudes of more than two miles, where oxygen is about 35 percent lower than at sea level.
