Why do we have art at all? There must be some evolutionary explanation. In this episode of the Aesthetics Bites podcast series, Stephen Davies discusses some of the evolutionary theories about where art came from in conversation with Nigel Warburton.  Aesthetics Bites is a podcast series of interviews with top thinkers in the philosophy of art. It is a collaboration between the London Aesthetics Forum and Philosophy Bites and is made possible by a grant from the British Society of Aesthetics .
