Document Summary
Outline: defining behavior, questions about behaviour, innate behaviour and adaptation, learning, Stimulus may be another animal or aspect of the env. Focuses on details of behaviour what is being observed? (attack/retreat). Focuses on mechanisms of behaviour how organism"s electrical system work to run Behavioral traits vary in flexibility and dependence on learning: behaviour falls in diff places on grid. Some behaviours like yawning (innate behaviour) and learning language (need a lot of flexibility) how flexible behaviour is (fixed to variant) and | is how much learning involved in response. Phenotype is related to genes and environment. P = g + e (behavioral phenotype = genes + environment) Slight differences in environment lead to variation in behaviours. -> fixed action patterns: unchangeable behavioral sequences (always 1-5) -> survival/fitness depends on innate behaviour (ex. kangaroos). -> highly stereotypical innate behavioral pattern that has 3 characteristics.
