"Our history is far richer and more complex than we imagined," said human evolutionary geneticist Aylwyn Scally.

Modern humans descended from not one, but at least two ancestral populations that drifted apart and later reconnected, long before modern humans spread across the globe.

Researchers discovered uniquely human neuroanatomical features in a study comparing human brains to macaque and chimpanzee ...

The human brain is more than seven times the expected size. Although evolution has enlarged the human brain, it hasn’t done so uniformly: some brain areas have ballooned more than others.
