Supernumerary, or extra, penises are very uncommon. Medical students uncovered a particularly rare case while dissecting a cadaver.

The human body evolved through adaptation and compromise, not perfect engineering. Human anatomy is less a story of perfect design and more one of evolutionary adaptation and compromise. Many common medical problems can be traced back to structures that evolved for entirely different purposes millions of years ago. The human body is often described as [...]

Wolves and humans share the same eye trait that helped both species become the ultimate pack hunters.

Human anatomy is far from complete, with ongoing discoveries reshaping understanding of variation, structure, and disease. Spend a few minutes with a biology textbook, scroll through fitness content, or overhear a conversation at the gym, and it can seem like the human body has already been fully mapped. Muscles are labeled, nerves are charted, and [...]

High-resolution X-ray offers a new look at an understudied organ: the clitoris.

Triceratops’ enormous nose may have been a built-in cooling system for its massive head. Triceratops and other horned dinosaurs had remarkably large nasal cavities compared with most animals. To understand what filled that space, researchers, including a team from the University of Tokyo, examined CT scans of fossilized Triceratops skulls and compared them with the [...]

__Humans have five main senses, of course, and there's even strongscientific agreement about a sixth: proprioception, or the ability to sense where our limbs are in space. But new research suggests we may also have a __"seventh sense." Scientists are calling it "remote touch."

A study out of Queen Mary University of London (QMUL) recently set out to examine how humans compare to common…
