When did we start kissing?

Have you ever considered when kissing first started? Who, or what, first decided that this was a good way to show affection?

Ancient historian, Troels Pank Arbøll, and hedgehog researcher, Sophie Lund Rasmussen, joined forces to attempt to find an answer. Cuneiform scripts, which are the world’s oldest written text, have the first mention of romantic kissing in a mythological narrative dating back to 2500 BCE.

But animals can also help us to answer this question. Bonobos have been shown to kiss romantically to strengthen pair bonds and assess a mate’s suitability. Perhaps the origins of kissing could be much older than human history! Find out more by listening to our latest podcast.
