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.
Around 3.5 million years ago, a gigantic energy flare punched out from the center of our galaxy, the Milky Way. The radiation it released erupted in two energized cones that were so powerful, the impact was felt 200,000 light-years away.
Another puzzle piece has been recovered in the quest to understand a close and relatively recent addition to the human family tree.
When humans are habitually exposed to cold water and air,
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.
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.
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.
One million of the planet's eight million species are threatened with extinction by humans, scientists warned Monday in what is described as the most comprehensive assessment of global nature loss ever.
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.
Early humans were still swinging from trees two million years ago, scientists have said, after confirming a set of contentious fossils represents a "missing link" in humanity's family tree.
Humans have unusually globular (or round) skulls and brains compared to our ancient ancestors -- including our closest extinct cousins the Neanderthals -- and a new study provides a possible explanation as to why.
