In the quest to understand how and why early humans started walking on two legs, scientists are now looking to chimpanzees ...

When did the first hominins start to walk upright? How long ago did the first bipedal species emerge? I think that the answer to these questions goes back a lot further than we all previously thought ...

Learn why our ancient ancestors maintained their climbing abilities once they developed their walking ones, and discover how their bipedalism evolved (possibly in the trees).

A new study on savannah-living chimpanzees could help answer some of paleoanthropology’s oldest questions about the origins ...

Habitual bipedalism is considered as a major breakthrough in human evolution and is the defining feature of hominins. Upright posture is presumably less stable than quadrupedal posture, but when ...

The acquisition of bipedalism is considered to be a decisive step in human evolution. Nevertheless, there is no consensus on its modalities and age, notably due to the lack of fossil remains. A ...

Analysis of Lucy’s fossil over the past 20 years has suggested that she and others of her species walked upright. But lead study author Dr. Ashleigh L.A. Wiseman, a research associate at the ...

A male western gorilla (Gorilla gorilla), photographed at the Bronx Zoo. The origin of human bipedalism has long been a hot topic among paleoanthropologists. At the very least it is seen as ...

Human bipedalism—walking upright on two legs—may have evolved in trees, and not on the ground as previously thought, according to a new study involving UCL researchers.

Many researchers think that bipedalism developed to enable humans to run faster or to enable us to carry tools and supplies. This new research suggests that it might have had another reason: to ...

The ability to move around on two legs, known as bipedalism, is a defining feature of modern humans. Yes, various other things make us human—a big brain, dexterous hands, language, material ...
