This is supposed to simulate evolution:

The genomes of the bots that found food and avoided poison were recombined by researchers, mimicking biological natural selection. To create a next generation bot, traits were combined and randomized to mimic biological mating and mutation. First simulated in software before using actual bots, five hundred generations were evolved this way with different selective pressures by roboticists and biologists at the Ecole Polytechnique Fédérale de Lausanne in Switzerland in 2007. "Under some conditions, sophisticated communication evolved," says biologist Lauent Keller of the University of Lausanne. "We saw colonies that used their lights to signal when they found food and others that used signals to communicate they had found poison."
