The simple act of chewing gum can raise the body’s metabolic rate by as much as 15 percent, a study finds.

Coppens, alongside Donald Johanson and Maurice Taieb, found a 3.2-million-year-old Australopithecus afarensis fossil in the 1970s.

In Chapter 7, “More Remarkable Encounters,” author Gregory Forth relays a story told to him by Tegu, a Lio man who says he found and disposed of a dead organism that might fit the description of an "ape-man."

Do members of Homo floresiensis still inhabit the Indonesian island where their fossils helped identify a new human species fewer than 20 years ago?

The Kenyan fossil finder is known for his discoveries of various Stone Age artifacts and ancient human skulls and skeletons.

Taieb recognized the potential importance of the Hadar Formation, where remains of the hominin Australopithecus afarensis were found only a few years later.

Researchers found the relatively high proportion of DNA from a hominin cousin—nearly 5 percent—when they scanned more than 1,000 genomes from 118 distinct ethnic groups.

A massive, well-preserved skull discovered in China in the 1930s belongs to a new species called Homo longi, researchers report, but experts remain skeptical about the evidence.

A selective advantage may have led the modern human Y chromosome to sweep through the Neanderthal population after it was introduced via interbreeding more than 100,000 years ago.

Africa’s sparse fossil record alone cannot reveal our species’ evolutionary history.

Modern human genomes and bones left behind from ancient hominins in Africa tell a complex story about the origins of our species.

A tooth and six bone fragments are the oldest confirmed Homo sapiens fossils in Europe.

An analysis of fossilized teeth sheds light on the evolutionary relationships between Pleistocene hominins.

A study points to the existence of an ancient human relative that interbred with Homo sapiens.

Researchers’ simulations suggest that small population sizes and inbreeding made Neanderthal populations vulnerable to chance fluctuations in population size.

The 12-million-year-old bones of a previously unknown species named Danuvius guggenmosi challenge the prevailing view about when and where our ancestors first started walking upright.

From skin color to immunity, human biology is linked to our archaic ancestry.

The astronomical idea doesn’t align well with the fossil record, anthropologists argue, but the origins of bipedalism are still difficult to determine.

See when and where our ancestors may have interbred with Neanderthals and Denisovans.
