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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Scientists uncover the developmental shifts that transformed the human pelvis and allowed our ancestors to walk on two legs.

If evolutionary biologist Terence D. Capellini were to rank the body parts that make us quintessentially human, the pelvis would place close to the top. After all, its design makes it possible for ...

The abdominal muscles provide postural support, protect internal organs, and perform other functions. In addition, the lower abdominal muscles help protect the pelvic cavity. The rectus abdominis is ...

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 ...

One of the characteristics that distinctly separates humans from other animals is the ability to walk on two legs. The key organ that enables this is the pelvis, but how the human pelvic structure, ...

Walking on two legs is the single most distinctive trait that separates humans from other primates. Unlike apes, our pelvis is short, broad, and bowl-shaped, and thus stable for walking upright while ...

Evolutionary anthropologists from the University of Vienna and colleagues now present evidence for a different explanation, published in PNAS. A larger bony pelvic canal is disadvantageous for the ...
