A protein that helps make human spit slimy reveals signs that the ancestors of modern humans interbred with an extinct human lineage that was an even more distant relation than Neanderthals.
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.
DNA in a fossil from a young girl has revealed that a mysterious extinct human lineage occupied Asia longer than previously thought, allowing more potential interbreeding with Neanderthals.
Some of the genes that up your risk of heart disease are also linked with having more kids, a new study finds.
The oldest known bones of our species, dating back around 300,000 years, have been discovered in a cave in Morocco.
Paleoanthropologists now also say a primitive-looking relative to modern humans was likely much smarter than the current understanding of the primitive hominins would suggest.
DNA from Neanderthals and a mysterious branch of humanity called Denisovans has been detected in the ancient mud of caves holding no fossilized remains of those individuals.
New research on Indonesian fossils reveals clues to an ancient expansion out of Africa led by human ancestors nicknamed "hobbits."
Scientists have found what they are saying could be the oldest evidence of human activity in North America — the marked bones of a mastodon dating back some 130,000 years.
A new study suggests that it is unlikely ancient hominins cannibalized each other as an easy alternative to going out and hunting.
Scientists have observed a chimpanzee cleaning the teeth of her adopted son, suggesting that humans might not be the only species with funerary rituals.
Fossils unearthed in China show a strange patchwork of features, with the large brains of modern humans; the low, broad skulls of earlier humans; and the inner ears of Neanderthals.

Humans can't seem to keep a tail, suggests new research that finds our early ancestors lost tails not just once, but twice.
Neanderthals and modern humans interbred long ago, but evolution has purged many of our caveman relative's genes from modern human genomes, a new study finds.
A group of humans migrating out of Africa some 40,000 to 70,000 years ago mingled with an as-yet unknown branch of humanity, three new studies have found.
