Some scientists believe humans became bipedal to adapt to climate change, but our closest primate ancestors complicate that ...

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 ...

Bipedalism in these ancestors isn’t exactly a surprise. The arm and leg bones analyzed in this study were found in Chad in 2001 alongside a nearly complete cranium, the study said.

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.

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 ...
