In the animal kingdom, penises can be spiked, split, corkscrewed—even detachable. They're one of the most diverse structures in biology. The human penis is so uniform, it's an anatomical outlier.

It all really comes down to habit. Once people get used to doing things one way — like using the word "horsepower" to refer to an engine's output — it can be exceedingly difficult to get them to ...

The mammals' mysterious clicks contain a stunning level of complexity, a new study shows. A group of sperm whales (Physeter macrocephalus) swims together in the Indian Ocean. For years, researchers ...
