Inbreeding may have helped cause Neanderthals to go extinct

Neanderthals went extinct around 40,000 years ago -- about the same time that modern humans migrated out of Africa. This has led researchers to believe that modern humans won the competition for resources, leading to the demise of Neanderthals.

Early humans breastfed their young for a year, study says

Three million years ago, Australopithecus africanus was one of the first human ancestor species to live across the southern African grasslands and forests. A new study of fossil teeth suggests that like modern humans, they breastfed their babies for up to a year after they were born.

210,000-year-old human skull in Greece oldest found outside Africa

Two skulls found in a Grecian cave paint a surprising portrait of who lived there hundreds of thousands of years ago. One fragmentary skull has been dated to 210,000 years ago, and researchers believe that it is the earliest evidence of modern humans living in Eurasia, according to a new study. The other, more complete skull belonged to a Neanderthal who lived 170,000 years ago.

Exploding stars may have motivated human ancestors to walk

When stars exploded within range of Earth 2.6 million years ago, it may have set certain things in motion that would cause human ancestors, called hominins, to go from swinging through the trees to walking upright, according to a new study.

This cave sheltered some of the first known humans

In the foothills of Siberia's Altai Mountains lies a cave that contains some of the keys to understanding the earliest humans to walk the Earth. Denisova Cave is the only place in the world where fossils have been found that belong to mysterious ancient humans called Denisovans.
