Researchers have digitally reconstructed the leg muscles of an ancient human ancestor that lived 3.2 million years ago, revealing they could stand and walk upright like modern humans.

How did human bipedalism evolve towards greater energy efficiency? By analyzing the occasional bipedal walking of baboons, ...

The upright posture is said to have enabled long-distance running and greater flexibility in locomotion. A quadruped will destroy us over a hundred yards, but we perform well as cross-country runners.

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 questions remain about the evolution of bipedalism. We still do not know why upright walking was selectively advantageous for our earliest ancestors and extinct relatives.
