A new study says honeybees can learn basic arithmetic.
According to a study published this week in Science Advances, scientists at RMIT University in Melbourne, Australia, have shown that honeybees can add and subtract if trained to do so. This discovery helps scientists understand the relationship between brain size and brain power, perhaps knocking birdbrain off the list of perceived slights. Honeybees and humans are separated by more than 400 million years of evolution, so the study’s authors say their findings suggest that an advanced understanding of numbers “may be more accessible to nonhuman animals than previously suspected.”
Many animals understand numbers at a basic level for essential tasks. But until now, only a few animals have demonstrated the ability to add and subtract. Honeybees join this short list that includes chimpanzees, African grey parrots and spiders.
The revelation that the tiny brain of a honeybee can understand basic mathematical operations has ramifications for the future development of artificial Intelligence, according to RMIT.
“This could give us insight on how to build more simple computers that can still process at a higher level … perhaps making computers more energy efficient,” said Scarlett R. Howard, the study’s lead author.
Training bees to do your homework won’t be an option, but here’s how the scientists helped them learn.
In this study, 14 free-flying honeybees were taught to recognize colors as “symbolic representations for addition and subtraction,” where blue is addition and yellow is subtraction.
Bees entered a Y-shaped maze. At the maze entrance, they viewed a sample set containing a specific number of blue or yellow shapes. Next, they flew through an opening and chose between two possible options: If the elements they first saw were blue, the bees would need to fly to the decision chamber that had one more than the sample they first saw (addition!). If the shapes were yellow, the bees would need to choose the option that contained one less shape than the sample (subtraction!).
In 100 trials, bees were rewarded with a drop of sugar water for the correct choice and punished for the wrong choice with a drop of quinine solution.
After training came the moment of truth in the testing phase: During tests that contained no reward or punishment, bees came up with the correct answers 63% to 72% of the time. That’s not random chance.
In this study, bees were tested on the number range of 1 to 5 for their ability to add and subtract. Howard notes it would be useful to examine how bees would perform on larger numbers, such as 2 plus 3, or moving on to test more complex operations.
