Intelligence was once thought to be uniquely human. But researchers have discovered astonishing cognitive abilities in many other species—not just our close cousins like chimps, or fellow mammals like dolphins—but also crows, parrots, and even octopuses.

Why do some species get an extra dose? And just how special are humans, really?
