Document Summary
Natural selection> increased efficiency of behaviors in particular environments. Reproducing= mating, taking care of babies *most important* Some individuals better able to produce more offspring > left more copies of their genes: behavioral ecology: the study of behavior from an evolutionary and ecological perspective. The aim is to understand why different species behave in different ways: behavior is a product of natural selection on ancestral populations resulting in increased adaptatio(cid:374) to a parti(cid:272)ular ha(cid:271)itat.

Social system evolves in response to ecological conditions. Social behavior is a suite of adaptations to the ecological and social (who is around you) environment. Who mates with who and what are the genetic consequences. For survival and fitness: (fitness being reproductive success) Defense of territory/food resources and mates from competitors.
