Cavemen Peter Evans visits a Palaeolithic cave to see evidence of our ancestors' musicality. Even playing stalactites came into their repertoire!
But could man's musical abilities have developed much earlier than this - more than two hundred thousand years ago?
Standing on two feet 'Yes' argues archaeologist Iain Morley. His research suggests our musical voice developed as we started walking on two legs. And this happened about 1.75 million years ago.
Musical intuition Music therapist Nigel Osborne and psychologist Colwyn Trevarthen push our innate musicality even further back. They believe our reaction to music is based on an intuitive mechanism evolved over billions of years.
Could this intuitive response explain why babies react to music so positively?
Peter Evans explores the evolutionary function of music in the first of a new series of Frontiers.
