The organic world – animals, plants, viruses – is the product of Darwinian evolution by natural selection. Natural selection expresses the idea that organisms (more accurately their genes) vary and that variability has consequences. Some variants are bad and go extinct; others are good and do exceptionally well. This process, repeated for two billion years, has given us the splendours of life on earth.

It has also given us the splendours of human culture. This may seem like a bold claim, but it is self-evidently true. People copy cultural artifacts – words, songs, images, ideas – all the time from other people. Copying is imperfect: there is "mutation". Some cultural mutants do better than others: most die but some are immensely successful; they catch on; they become hits. This process, repeated for fifty thousand years, has given us all that we make, say and do; it is the process of "cultural evolution".

However, the underlying mechanisms are poorly understood. For example, how important is human creative input compared to audience selection? Is progress smooth and continuous or step-like? We set up DarwinTunes as a test-bed for the evolution of music, the oldest and most widespread form of culture; and, thanks to your participation, we're starting to get answers.

Here's a link to our recent PNAS paper and here are the audio results of our initial experiment:
