Every step you take depends on a structure most people rarely think about. The pelvis sits at the center of the body and quietly supports nearly every movement. It holds the spine upright, steadies ...

A study published in Nature identified two structural innovations in the upper human pelvis that enabled bipedalism and reported associated genetic programs active during development. Researchers from ...

Walking upright on two legs is one of the key traits that sets humans apart from other primates. Now, scientists are beginning to unravel some of the developmental and genetic mysteries underpinning ...

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 ...

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 ...

Fossil remains of the human pelvis are rare because the pelvic bones do not preserve very well. Therefore, it has remained unclear when human sex differences in the pelvis evolved: jointly with ...

The wide, basin-shaped pelvis of modern humans helps us walk upright on two legs and give birth safely to babies with large heads. Pixabay Walking upright on two legs is one of the key traits that ...

Human childbirth is comparatively difficult because our babies' heads are large relative to our birth canals. This tight 'fetopelvic' fit increases the risk of obstructed labor, which in turn has ...
