Every step you take depends on a structure most people rarely think about. The pelvis sits at the center of the body and ...

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 ...

A 3.4M-year-old set of foot bones from Ethiopia is forcing paleoanthropologists to redraw one of the most familiar diagrams ...

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 ...

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 ...

A big difference between humans and other apes is the ability to stride easily around on two feet, with our bodies vertical. Now, a new analysis of some fossil bones shows that adaptations for bipedal ...

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 5 million years, but the precise ...

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 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 ...
