In a remarkable new study, crows demonstrated an intuitive grasp of geometry—identifying irregular shapes without training.

A seemingly simple math problem about dividing pizzas sparked debate when someone highlighted a potential flaw in the assumed answer.

W hen most people think of shapes, they imagine a triangle, a rectangle, or maybe even a fancier- sounding rhombus or ...

Crows in a lab were able to distinguish shapes that exhibited right angles, parallel lines, and symmetry, suggesting that, like humans, they have a special ability to perceive geometric regularity.
