Learning objectives: define / explain the significance of all red terms, distinguish between the potential outcomes of the act of communication (mutualism, altruism, manipulation, spiteful) and identify the outcome from a given example. 3. define ritualization and describe how a behaviour becomes ritualized. 4. from a given example, identify what information is being sent through a signal (e. g. alarm, sharing information about a resource, etc. ) 5. define altruism and describe the potential hypotheses discussed for its evolution in lecture. From a given example, identify what hypothesis is likely at work. Communication: process in which a specialized signal produced by one individual affects the behaviour of another individual. Signal: an evolved trait that is selected for its effect on the behaviour of the receiver. E. g. focus of this part of the lecture. Cue: consistent aspects of the environment that can guide the behaviour of an individual in a way to enhance its fitness. E. g. mosquitos using co2 concentrations to detect prey.
