Pick up an object that’s close at hand. Throw it at something, or even someone (but gently, of course!) You’ve just reenacted what appears to be a pivotal stage in human evolution, when a propensity for projectiles shaped cognitive powers that later became language and symbolic thought.

That, at least, is one hypothesis for how humans became so smart. And now researchers have found support in chimpanzees, among whom the ability to throw goes hand-in-hand with increased intelligence and brain development.
