What separates humans from other animals? Some of the answers might surprise you.
Humans are unique creatures on the planet, though it wasn't always this way. Long ago, some bizarre human relatives, such as Nutcracker Man and a Homo species whose miniature bodies resembled the hobbits on Lord of the Rings, roamed Earth. Scientists are even finding evidence that modern humans crossed paths with some of our relatives, with fossils suggesting Homo sapiens may have had sex with Neanderthals and even a newly discovered species called the Denisovans. In news and features, we will cover human evolution and origins, revealing the mysteries of humanity, details on human ancestors and the evolutionary steps that led to modern humans.
Scientists who forced volunteers to chew raw goat flesh (yes, chew) have found that such meat-gnawing likely caused human teeth and jaws to shrink throughout our evolutionary history.
Wisdom teeth may have shrunk during human evolution as part of changes that started with human tool use, according to a new study.
Ancient trysts between Neanderthals and modern humans may have influenced modern risks for depression, heart attacks, nicotine addiction, obesity and other health problems, researchers said.
Stone tools discovered on the Indonesian island of Sulawesi dating back at least 118,000 years suggest that an unknown lineage of toolmakers, relatives of the diminutive "hobbit" once lived there.
Ancient hominins may have harnessed fire from nearby lava flows to cook food, keep warm and evolve bigger and smarter brains, new research proposes.
Neanderthals had protruding facial features because of the way their bodies deposited and dealt with bone, a new study finds.
Monkeys that are revolted by often disease-carrying things such as poop suggest that disgust drives cleanliness - and health.
Just in time for Halloween, gore-resistant scientists are swinging frozen human cadaver arms like battering rams — in the name of science, of course.
The evolutionary response to threat may explain why some want to close the doors to migrants in Europe — but the brain can override those impulses.
