Theory suggests that signals between prey and predator can coevolve. In order for an “I see you” display to evolve, the prey species must be able to back up its “I see you” with action, by outrunning the predator, collective mobbing, escape to a refuge or any other mechanism that prevents the predator from making a kill. Without such action, even if it is rarely applied, it is difficult to see how an “I see you” display could evolve.
