Scientists trained honeybees to recognise human faces, showing how tiny brains can distinguish faces by the arrangement of their features |– timesofindia.indiatimes.com

Honeybees can be trained with nothing more than the promise of a sugary reward; they learn to pick out a specific face and keep picking it out later, even when it appears from a slightly different angle or sits among faces they have never encountered before. It is a strange and slightly humbling discovery, not because bees have any use for recognising people, but because it forces a rethink of how much brainpower a task like this actually needs. Two separate studies, a decade apart, chipped away at this question from different angles, and together they tell a fuller story than either one does alone.
