In animal communication natural selection favors callers who vocalize to affect [i.e. manipulate] the behavior of listeners and listeners who [are selected to] acquire information from vocalizations. . . . Whereas signalers may vocalize to change a listener’s behavior, they do not call to inform others. Listeners acquire information from signalers who do not, in the human sense, intend to provide it.—Robert Seyfarth and Dorothy Cheney  “Signalers and Receivers in Animal Communication” (2003)
