What to know about Animal Cognition

Researchers from three Finnish universities have published a study in the journal Science demonstrating that bumble bees can solve a novel object-manipulation task without prior training. The findings suggest that spontaneous problem-solving is possible in insects, challenging previous assumptions that such abilities were limited to larger-brained vertebrates.

What happened

Bumble bees show spontaneous problem-solving, challenging big-brain assumptions Sadie Harley Scientific Editor Robert Egan Associate Editor In a new study, bumble bees solve a completely novel object-manipulation task.

Why it matters

What makes this behavior especially remarkable is that the bees had never been trained.

Common ground

The findings challenge the long-standing assumption that spontaneous problem-solving is restricted to humans and other large-brained vertebrates.

Claim 1: “the bees were not trained to move the ball underneath the flower. Instead, they only learned two separate pieces of information beforehand: that the blue artificial flower contained a reward, and that the ball was a movable, non-threatening object”
CORROBORATED
Multiple sources confirm the bees were not trained on the solution itself, but were familiar with the reward signal (blue flower) and the ball as a movable object.
