In this lecture, we will introduce basic theories of communication and the evolution of communication in animal behavior. We focus on the relationship between communications and signals as well as how signals can evolve from cues and then be further elaborated with stereotypy and redundancy (possibly leading to multi-modal communication). This also gives an opportunity to introduce autocommunication, public information, and eavesdropping.
Topic highlights:
- the relationship between a communicating pair of sender and receiver and the signals between them
- the distinction between a signal and a cue
- autocommunication
- the evolution of communication/signaling
- cue ritualization, noise, stereotypy, and redundancy
- visual semaphoring by some animals
- opportunities for exploiting communication
- public information and eavesdropping
Important terms: communication, signal, cue, ritualization, stereotypy, redundancy, autocommunication, co-option, exaptation, noise, semaphore/sempahoring, public information, eavesdropping, concealment, private information, multimodal communication
