Bees Can Do Basic Mathematics

The ability to manipulate numbers using abstract rules was long considered a hallmark of primates and other large-brained animals. However, groundbreaking research has revealed that even the tiny honeybee possesses a knack for arithmetic. In a clever experiment, individual bees were trained in a Y-shaped maze. They were first shown a number of shapes of a certain color; if the shapes were blue, the bee learned this was a cue to "add one," and if they were yellow, the cue was to "subtract one." The bee would then have to fly to the chamber displaying the correct answer to receive a sugary reward.

Astonishingly, the bees could consistently apply these learned rules to new numbers they hadn't seen during training, demonstrating a true understanding of the concepts rather than simple memorization. This discovery is remarkable because a bee's brain contains fewer than one million neurons, compared to the 86 billion in a human brain. It suggests that complex numerical cognition doesn't necessarily require massive neural architecture. While bees don't need to balance a budget, this cognitive flexibility may be an evolutionary tool that aids in complex tasks like foraging, helping them remember distances and landmarks to locate the best sources of nectar.
