Document Summary
Ethologists focused on the behavior of animals in their natural environment: ethology- studying animals in natural environment; believed behaviors were genetically determined if they are performed without learning, are stereotypic, and cannot be modified by learning. Ethologists probed the causes of behavior: by interbreeding closely related species, tinbergen"s four questions: Causation- what is stimulus and how can the relationship between stimulus and behavior by modified by learning. Development- what experiences is need for behavior to be displayed, and how does age affect behavior. Function- how does behavior effect survival and function. Evolution- how does behavior compare in related species, and how did it evolve: causes and development are proximate causes (look at immediate behavior) and function and evolution look at ultimate causes. Breeding experiments can produce behavioral phenotypes: few behaviors can be linked to a single gene. Knockout experiments can reveal the roles of specific genes: ex.
