The Kiss

from The Why Factor · host BBC World Service

Why do humans kiss? You might think it is a universal trait, something that we all do. But when European explorers travelled the world, they met tribes that didn’t kiss. So is it a learnt response after all? It can be used as a greeting, a sign of reverence or supplication, but we will be talking about the romantic kiss: Face to face, lips to lips. We examine the biochemistry, psychology, anthropology and history of kissing. Where does it come from? Image: Two women kissing at a festival (Credit: AFP/Getty Images)
