BLG 144 Lecture Notes - Lecture 20: Eusociality, Bluegill, Monarch Butterfly
Document Summary
Aim is to understand how and why animal"s behaviour is adaptive to the environment it habits. Natural selection heritable variation with competition for survival and reproduction. Behaviour to evolve: - must have alternative behaviour. Fixed action potential (fap): highly inflexible and stereotyped behaviour patterns. Mousse jumping (response to a stimuli) when he hears a rattle snake (sound = stimuli) Answer: related to causation neurological, hormonal and skeletal- muscular mechanisms; and developmental: learning from parents and plus in genes to learn that behaviour. Innate behavior inherited; does not have to be learned (little variation on learning) Most animals are not stimuli machine; they actually process the info about the environment change and actually make decisions through observation and learning and show flexibility. Most behaviour is flexible and conditioned-dependant use a framework cost-benefit analysis how animals tend to weigh cost and benefit before responding to a situation in various ways.
