Fossils offer a glimpse into Earth's distant past. They provide insights into extinct animals and plants, as well as past ecosystems. However, the fossil record is incomplete: Fossilization is rare, and only a small fraction ...

Endurance running or endurance diving—which came first?

A new study combines paleoanthropology and diving physiology to address a fundamental question in human evolution: Why did humans evolve their exceptional aerobic endurance? Did our ancestors begin endurance running to exhaust ...

Bone strength study reveals new clues about human evolution

Bipedalism, or walking on two legs, is one of the key features that distinguishes humans from other apes. But when and why our ancestors transitioned from a life often spent in trees to a life spent almost exclusively on ...
