The same process can be also observed in human society where cultural artifacts – words, songs, images, ideas – are constantly remixed and reinterpreted by people. A reinterpretation is an imperfect copy and therefore a “mutation”. Thus, the variety of our culture is the result of a cultural evolution.
In order to examine the underlying mechanism of cultural evolution, Robert M. MacCalluma, Matthias Mauch, Austin Burta, and Armand M. Leroia constructed a Darwinian music engine consisting of a population of short audio loops that sexually reproduce and mutate.
The selection is based on human feedback via a webpage that implements the remixing of tunes as a game. By remixing your tune with others, the other parent gets a score point. Your goal is to make an attractive tune - the more often you get remixed, the more points you have.
In 2010, researchers from the Alpen-Adria-Universität Klagenfurt released a similar system where people could vote for recombinations of music tunes.
