Researchers have significantly expanded the catalogue of known human genetic variation. The resulting datasets, shared in two back-to-back publications in the journal Nature, constitute what may be ...

Researchers have mapped variation in human stem cells that explains how cells of an individual may shape a unique 'developmental dance' at the molecular level, thereby controlling how the brain and ...

It is often assumed that modern humans are no longer evolving. But there is now considerable agreement among scientists that evolution is still affecting our species—and this process is taking place ...

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 groundbreaking DNA study has unveiled a hidden chapter in human evolution, revealing that all modern humans evolved from two ancient and distinct groups. This research, published in March 2025, ...
