Scientists tested crows on their ability to recognize “geometric regularity,” a skill previously assumed to be unique to humans ...

Squares, triangles, circles - these geometric shapes appear everywhere in art and architecture going back all through human history. Geometric regularity seems to be something that the human brain ...
