Cognition and Locomotion

Hugo Mercier and Dan Sperber:

Cognition is first and foremost a means for organisms that can move around to react appropriately to risks and opportunities presented by their environment. Cognition didn’t evolve in plants, which stay put, but in animals that are capable of locomotion. Cognition without locomotion would be wasteful. Locomotion without cognition would be fatal.
