A graphical tour of our evolutionary advantages starts with anatomy

The capacity to engage in shared tasks such as hunting large game and building cities may be what separated modern humans from our primate cousins

More proof of recent and rapid human evolution

New ideas about human evolution reveal just how unique Homo sapiens are

The latest molecular analyses and fossil finds suggest that the story of human evolution is far more complex—and more interesting—than anyone imagined

Our ability to cooperate in large societies has deep evolutionary roots in the animal kingdom

Psychologist/primatologist Michael Tomasello explains

For 30,000 years our species has been changing remarkably quickly. And we're not done yet
