000139388 520__ $$aReliable information is a crucial factor influencing decision-making, and thus  fitness in all animals. A common source of information comes from  inadvertent cues produced by the behavior of conspecifics. Here we use a  system of experimental evolution with robots foraging in an arena containing  a food source to study how communication strategies can evolve to regulate  information provided by such cues. Robots could produce information by  emitting blue light, which other robots could perceive with their cameras.  Over the first few generations, robots quickly evolved to successfully locate  the food, while emitting light randomly. This resulted in a high intensity of  light near food, which provided social information allowing other robots to  more rapidly find the food. Because robots were competing for food, they  were quickly selected to conceal this information. However, they never  completely ceased to produce information. Detailed analyses revealed that  this somewhat surprising result was due to the strength of selection in  suppressing information declining concomitantly with the reduction in  information content. Accordingly, a stable equilibrium with low information  and considerable variation in communicative behaviors was attained by  mutation-selection. Because a similar co-evolutionary process should be  common in natural systems, this may explain why communicative strategies  are so variable in many animal species.
