Bots Model Language Evolution

Researchers in Switzerland have done an interesting experiment in language evolution. Part of the experiment involved evolving virtual robots in a kind of genetic algorithm, with the final stage consisting of physical-ized robots using the pre-evolved genome from the virtual genetic hothouse. The story is reported at the Telegraph,
