Communication models must include eavesdroppers as evolutionary actors

Evidence

In communication there is a sender and a receiver connected by an informative signal. A third subject is the eavesdropper or the involuntary receiver that utilizes the information which circulates between the two. Eavesdropping represents an important evolutionary phenomenon. Communication is costly in term of energy budget allocated by vocal individuals, and a well-designed communicative framework should be the result of selective pressure. — Almo Farina, Soundscape Ecology, 540
