Teeth and jaw fossils discovered in Ethiopia provide a link between two species of early human ancestors, filling a crucial gap in human evolution, scientists have announced.
Genome researchers have identified more than 700 regions in human DNA where apparently strong selection has occurred, driving the spread of genes linked to traits from bone structure to skin color.
It may be a threat to humans' long-term future on the planet, but climate change may have helped bring us into being in the first place, some scientists say.
A study of ancient cemeteries in North America suggests that a prehistoric baby boom swept the continent about 2,500 years ago, just as farming was taking root.
Europeans inherit their looks from Stone Age hunters, according to a new study, which compared facial features of modern Europeans with those of ancient skeletons.
Early humans colonized northern Europe 200,000 years earlier than previously thought, as shown by ancient stone tools discovered along the British coast.
At least two distinct groups of early humans colonized the Americas, a new study says, reviving the debate about who the first Americans were and when they arrived.
Footprintlike marks found in Mexico have recently been dated at over a million years old, renewing debate about when humans first arrived in the Americas.
New research suggests that before reaching Europe modern humans arrived in India, where they created some of the earliest human culture and drove an older hominid species to extinction.
Wildlife is becoming "globalized," biologists warn, as the spread of animals and plants makes species more homogenous at the expense of regionally unique varieties.
