Bumblebees Able to Problem Solve Despite Having Tiny Brains
Researchers found 23 of 30 buff-tailed bumblebees solved a ball puzzle without specific training, suggesting goal-directed problem solving.
- On Thursday, researchers published a study in Science showing bumblebees spontaneously rolled a plastic foam ball underneath an artificial flower to reach a sugary reward, demonstrating advanced problem-solving previously observed only in vertebrates.
- German psychologist Wolfgang Kohler established this research tradition more than 100 years ago by tasking chimpanzees with stacking boxes to reach a banana, a classic test that inspired the current insect study.
- University of Oulu researchers tested 30 bees in a rectangular arena, finding 23 succeeded at moving the ball to the correct location, with 16 doing so without trial-and-error or prior training.
- Senior researcher Olli Loukola of the University of Turku stated the findings do not imply human-like reasoning but prove miniature brains can generate flexible solutions to novel problems in unexpected ways.
- Scientists suggest spontaneous, goal-directed problem-solving can emerge in animals with vastly smaller brains than vertebrates, positioning insects as worthy subjects in advanced cognitive research for the first time.

The brain of a bumblebee consists of only one million nerve cells and is able to perform amazingly. An experiment shows how well the insects solve problems independently.
Untrained bumble bees demonstrate spontaneous problem-solving in study
A century ago, a psychologist named Wolfgang Köhler proved that chimpanzees could solve complex problems. He hung a banana high out of reach. The chimps sat, thought, and suddenly stacked wooden boxes to reach the fruit. It became the definitive proof of animal insight. Now, an insect is crashing the party. Researchers in Finland have revealed that bumble bees (Bombus terrestris) can solve an insect version of the classic “box-and-banana” proble…
The German psychologist Wolfgang Köhler proved more than a hundred years ago that chimpanzees could solve new problems by combining objects in unexpected ways, such as stacking boxes to reach a banana beyond their reach.These experiments became some of the first and most influential demonstrations of insight and spontaneous problem solving in animals.So far, it was estimated that only humans and other vertebrates with large brains had the cognit…
