All vertebrate species have a pelvis, but only humans use it for upright, two-legged walking. The evolution of the human pelvis, and our two-legged gait, dates back five million years, but the precise ...

The pelvis is often called the keystone of upright movement. It helps explain how human ancestors left life on all fours behind. Yet the “how” has stayed fuzzy for decades. A new Nature study led by ...

Two small changes in human DNA may have played a big role in helping our ancestors walk upright, researchers say. The study, recently published in the journal Nature, found that these tweaks changed ...

Ardi is the oldest known partial skeleton of a hominin and shows foot features that are transitioning from vertical climbing to bipedal walking. While Ardi has the primitive grasping big toe of the ...

Two small genetic changes reshaped the human pelvis, setting our early ancestors on the path to upright walking, scientists say. One genetic change flipped the ilium — the bone your hands rest on when ...
