Document Summary

Very low frequencies of sound, giving coastlines and mountain chains. Behaviour can evolve into systems of information exchange communication, which may become elaborated as displays or signals, if it benefits both the sender and receiver. Animals communicate using sensory modes, differing in how it is performed, properties of signals, and what can be communicated. Visual signals: easy to produce, come in endless variety, can be changed rapidly, clear indicate position of signaller: not useful at night or low light areas; predators can use deception. Pheromones: molecules used for chemical communication btwn individuals of same species; specific, information-rich messages: ex mammals marking territory/trails remain in environment longer than visual signals, but not rapid exchange. Many degrees of social system complexity exist among living species social systems are dynamic; individuals repeatedly communicate with one another and adjust relationships b/c costs and benefits experienced by individuals change with age, sex, physiological condition, status.
