The pelvis is often called the keystone of upright movement. It helps explain how human ancestors left life on all fours ...

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 ...

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, ...

Harvard scientists have discovered new evolutionary changes in pelvic structure that allowed the first humans to walk upright on two legs. The August study published in the journal Nature reveals 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 ...

The size of the neonatal skull is large relative to the dimensions of the birth canal in the female pelvis. This is the reason why childbirth is slower and more difficult in humans than in most other ...

A fossilized human-like pelvis that was discovered by researchers and dated by a UA scientist could help answer questions about how humans evolved, according to findings made public today. 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 ...

This article was published in Scientific American’s former blog network and reflects the views of the author, not necessarily those of Scientific American Human babies enter the world utterly ...

An analysis of 2 million-year-old bones found in South Africa offers the most powerful case so far in identifying the transitional figure that came before modern humans — findings some are calling a ...

Human birth is far more challenging than that of other primates. In 1960, anthropologist Sherwood Washburn proposed a widely accepted explanation for the tight squeeze a baby experiences passing ...
