In this EdgeVideo, evolutionary biologist Armand Leroi reports on his art/science conversation and collaboration with musician Brian Eno which began when the two sat next to each other an an Edge dinner in London. The dinner discussion began with evolution and music, proceeded to the evolution of music, and led to the following question: has anybody attempted to reconstruct the history of human song? People around the world sing in different ways. Is it possible to retrieve that history. Can we do for songs what we’ve done for genes, for language?
