Bees Surprise Scientists with Unexpected Mental Abilities
A new scientific study has revealed that bumblebees are capable of using tools to solve relatively complex problems, a discovery that adds the insects to a limited list of creatures known for their flexible thinking and unusual problem-solving abilities.
The study, published in the journal Science, showed that bees successfully completed a modified version of a famous experiment known from about a century ago as the "Box and Banana Problem," which was originally used to demonstrate chimpanzees' ability to devise solutions to access food.
An Unprecedented Experiment
During the experiment, researchers trained a group of bees to attach a blue artificial flower to a reward of sugar water. The flower was then moved to the ceiling of a transparent chamber, out of the bees' reach. To reach it.
The bees had to push a small polystyrene ball to the correct location below the flower and then climb over it to reach the reward—a sequence of behaviors they had not previously been trained to perform. The results showed that 75% of the bees successfully solved the problem in the original version of the test.
In this context, Dr. Olli Lokola, a researcher in animal behavior at the University of Oulu in Finland and the study's supervisor, said that this experiment represents the insect version of the classic "box and banana" test. He explained that the result lies in the bees' understanding that they can move an object and use it as a tool to reach a goal that is not directly accessible.

A More Complex Test
To ensure that the success was not merely a coincidence, the scientists designed a more complex version of the experiment. After allowing the bees to see the location of the flower, the visual cues that enabled them to see it directly were turned off. They then had to remember its location and move the ball to the correct spot using only their memory. Twenty-three out of thirty bees successfully completed the task, which the researchers considered further evidence that bees possess more complex cognitive abilities than previously thought.

Small Brains, Big Capabilities
The researchers emphasized that they are not claiming that bees think in the same way as humans, but the results indicate that very small brains can produce flexible solutions to novel problems.
Professor Lars Chittka, an insect behavior specialist at Queen Mary University of London and author of "The Brain of the Bee," said these findings represent the clearest evidence yet that bees possess some kind of understanding of the problem they face.

He added that while intelligence is often linked to brain size, bees provide a striking example of the level of intelligence that can be achieved with extremely small nervous systems.
These findings join a growing body of research demonstrating that bees are capable of counting, learning, pattern recognition, and manipulating objects in complex ways, reinforcing the growing scientific view that insects possess cognitive abilities far exceeding previous assumptions.
