An exciting new study has demonstrated that bumblebees can teach other bumblebees how to solve a puzzle to earn a reward. Even though the size of a bumblebee's brain is as small as the head of a pin, these bees exhibit some of the most complex and intricate behaviors anywhere in the animal kingdom. After the bumblebees in this study learned how to solve the puzzle, they taught the skill to other bees. While the other bees tried different versions of the behavior, they ultimately reverted to using the techniques they were taught to solve the puzzle. At its most simple, culture is defined as behavior learned by someone else, i.e.,"social learning."
