Are they watching YOU? Bees and wasps can recognise and learn different faces

It seems insects might be able to see much more than we previously thought. New research has revealed that both the honeybees and wasps are able to learn achromatic (black and white) images of human faces. Despite having tiny brains made up of just one million brain cells – compared to the 86 billion that make up a human brain – they appear to visually process faces in a similar way to how we do. This is despite them having no evolutionary reason for doing so, writes Dr Adrian Dyer, an associate professor from RMIT University in Australia for The Conversation. Understanding how this developed could help researchers create smarter artificial intelligence, Dr Dyer says.
