We taught bees a simple number language, and they got it

Bees join an elite group of species that understands the concept of zero as a numberTo train honeybees to match symbols and number amounts , we used a subset of the symbols previously used to train pigeons on a similar task.Bees were trained to fly into a Y-shaped maze. Inside the maze the bee would view a stimulus. The bee would then fly into the decision chamber were it would view two options, one correct and one incorrect.

For example, if a bee viewed an N-shaped sign, she would need to choose a display presenting two items. She would need to be able to do this regardless of the shape, pattern, or colour of the items presented. Interestingly, however, we found bees were unable to reverse their learnt tasks. If a bee had learnt to match a sign to a numerosity, she could not then match a numerosity to a sign, or vice versa. It appears the association between the number and the symbolic representation was only learnt in one direction and was unable to be reversed.” – are sometimes applicable to how humans learn too.
