Scientists uncover fossils suggesting Sahelanthropus tchadensis, a 7-million-year-old ancestor, could walk upright. Could this tiny bipedal ape-like hominin rewrite what we know about the earliest ...

A seven-million-year-old fossil may rewrite human origins, showing our ancestors were walking upright far earlier than anyone expected.

A long-running and bitterly fought dispute over whether the earliest known hominin had a knuckle-walking gait, like ...

A big difference between humans and other apes is the ability to stride easily on two feet. A new analysis of fossil bones shows that adaptations for bipedal walking go back 7 million years.

You will be hard-pressed to find an animal that has no rudimentary or useless traits: Atrophied eyes, discarded wings, or male breasts, to name just a few of many. In males, for example, what is the ...

Humans might have evolved our two-footed posture for its fighting advantage; we punch harder standing than on all fours, and downward punches are much more forceful than upward ones. This could also ...

The inner ear may not seem like a particularly bony place, but human ears in fact have three small bones (also known as ossicles): the malleus, the incus and the stapes. While most people would assume ...

One of the biggest questions in human evolution asks why humans became habitually bipedal about 7 million years ago. Most of our primate cousins do well walking quadrupedally and switch to two legs ...

In fact, over 85% of the occurrences of bipedalism that were observed took place when the apes were in the trees. "Our study suggests that the retreat of forests in the late Miocene-Pliocene era ...
