When animals move, forage or generally go about their lives, they provide inadvertent cues that can signal information to other individuals. If that creates a conflict of interest, natural selection will favour individuals that can suppress or tweak that information, be it through stealth, camouflage, jamming or flat-out lies. As in the robot experiment, these processes could help to explain the huge variety of deceptive strategies in the natural world.

The article at Not Exactly Rocket Science, describes an experiment in which robots competed for food at a hidden location and controlled a visible signal that could be used to reveal their location.  The robots adapted their signaling strategy by a process that simulates natural selection.  Eventually, the robots learned not to pay attention to others’ signals and the signals become essentially uninformative.
