In 2001, researchers unearthed a scattering of fossils beneath the windswept dunes of the Djurab Desert of northern Chad. The remains were later identified as belonging to an extinct species, ...

It’s considered to be one of the most decisive steps in human evolution. Now, scientists believe they have pinpointed when our ancestors made the transition from walking on all fours to standing on ...

Every step you take depends on a structure most people rarely think about. The pelvis sits at the center of the body and quietly supports nearly every movement. It holds the spine upright, steadies ...

For centuries, the question of how humans became upright walkers has fascinated scientists and philosophers. Charles Darwin famously argued in The Descent of Man (1871) that humans evolved from apes, ...

The oldest distinguishing feature between humans and our ape cousins is our ability to walk on two legs – a trait known as bipedalism. Among mammals, only humans and our ancestors perform this ...

Scientists may have cracked the case of whether a seven-million-year-old fossil could walk upright. A new study found strong anatomical evidence that Sahelanthropus tchadensis was bipedal, including a ...

The wide, basin-shaped pelvis of modern humans helps us walk upright on two legs and give birth safely to babies with large heads. Pixabay Walking upright on two legs is one of the key traits that ...

The pelvis is often called the keystone of upright locomotion. More than any other part of our lower body, it has been radically altered over millions of years to allow us to accomplish our bizarre ...

The chimp with the most human-like gait and body type walked upright more efficiently than he knuckle-walked a finding that study co-author Herman Pontzer calls a snapshot of how this evolution may ...

The oldest distinguishing feature between humans and our ape cousins is our ability to walk on two legs—a trait known as bipedalism. Among mammals, only humans and our ancestors perform this atypical ...
