Bees can recognise human faces — and remember them
Honeybees can be trained to recognise individual human faces, distinguishing between them with surprising accuracy. They use a technique called 'configural processing' — combining facial features as a whole rather than individual parts — similar to how humans do it. Bees can remember a face for at least 48 hours. Given that bee brains contain fewer than a million neurons (versus 86 billion in humans), this suggests face recognition doesn't require a large or complex brain.
Face recognition feels like a distinctly human and primate ability. Finding it in an insect with a pin-sized brain challenges fundamental assumptions about the minimum cognitive hardware required for sophisticated social identification.
