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 ...

Many of the body's biggest flaws are the result of evolution building on old designs instead of starting over. Our spine, eyes, teeth, pelvis, and even certain nerves all reveal compromises that ...

The pelvis is the part of the human skeleton with the largest differences between females and males. The female birth canal is on average more spacious and exhibits shape features that enable birth of ...

A combined study on the morphology of the human pelvis – leveraging genetics and deep learning on data from more than 31,000 individuals – reveals genetic links between pelvic structure and function, ...

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 ...

For decades, one idea has shaped discussions about human evolution and birth: humans endure unusually difficult childbirth ...

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 ...

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 ...
