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 have discovered 2.8-million-year-old fossils of what may be a new human species in Ethiopia.
A single gene that is found only in Homo species may partly explain why the human neocortex, the seat of higher cognitive functions, is so large.
A partial skull found at a site called Lukenya Hill in Kenya suggests that early populations of modern humans in Africa had greater diversity than previously thought.
In addition to good looks, charm and intelligence, there's a more surprising reason two people may choose to spend Valentine's Day together: having similar microbes.
Discovery of partial skull in Israel may provide insights on humans' migration out of Africa and when they first interbred with Neanderthals.
An ancient human fossil discovered from the seafloor near Taiwan reveals that a primitive group of humans, potentially an unknown species, once lived in Asia, researchers say.
The ancestors of humans may have evolved powerful, precise humanlike hands enough to use stone tools long before such tools were even developed, researchers say.
Our human ancestors began tasting food differently sometime after the human family tree branched off from the ancestors of chimpanzees, researchers say.
The ancient, big-bodied relatives of modern-day humans not only ate freshwater shellfish, but engraved their shells and used them as tools, a new study finds.
A second look at a century-old shell collection uncovered remarkable engravings made on a freshwater shellfish shell in Java, Indonesia.
The ancestors of modern humans began evolving the ability to digest alcohol about 10 million years ago, new research finds.
