BEHAVIORAL ECOLOGY- 4 ways evolution has been used to study behaviorHistorical/phylogenic approachTesting adaptive value through experimentation (ethologists)Comparative approach – involves looking at a collection of species, and often they share similar environment but at some instances, they may have different environment. Thus due to different environment, have some different traits. You can take a set of species that are quite distant, raise them in similar environment get similar traits. Predictive approachInvolves hypothesis derived from evolutionary theory that predict the nature of behavior and then testing those hypotheses with behavioral data from extant species. - Peppered moth: Kettlewell2 different color forms within species. With industrial pollution, hypothesized that it changed them. Crypsis: the camouflage or protective appearance of an animalDark vs light moth. Kettlewell did it at the trunk, not at the junction of the branch where moths are usually there.
