Quinn M. (2001) Evolving Communication without Dedicated Communication Channels. In: Kelemen J., Sosík P. (eds) Advances in Artificial Life. ECAL 2001. Lecture Notes in Computer Science, vol 2159. Springer, Berlin, Heidelberg
Artificial Life models have consistently implemented communication as an exchange of signals over dedicated and functionally isolated channels. I argue that such a feature prevents models from providing a satisfactory account of the origins of communication and present a model in which there are no dedicated channels. Agents controlled by neural networks and equipped with proximity sensors and wheels are presented with a co-ordinated movement task. It is observed that functional, but non-communicative, behaviours which evolve in the early stages of the simulation both make possible, and form the basis of, the communicative behaviour which subsequently evolves.
