BioNB 221: Lecture 6 Sept. 10, 2008 Page 1 Lecture 6: Principles of Communication Professor Robert Raguso 1. What is communication? Definition: the process in which a sender uses a specially evolved signal to modify the behavior of the receiver Important points: a. "specially evolved signal" this narrows considerably the definition because it eliminates cases where the behavior of one animal influences that of another without a specially evolved signal being involved example: a mouse making rustling sounds is not communicating with the owl that is hunting it this also implies that the response of the receiver has, on average, benefited the sender, for otherwise natural selection would not have favored the production of the signal b. "modify the behavior of the receiver" note the neutrality of this with respect to the effects on the receiver's fitness; the act of communication may increase or decrease the receiver's fitness
