suggested that understanding any behavior requires answering as 4 summarized questions
1. What stimulus elicits the behavior, and what physiological mechanisms mediate the response?
2. How does the animal's experience during growth and development influence the response?
3. How does the behavior aid survival and reproduction?
4. What is the behavior's evolutionary history?
1. What stimulus elicits the behavior, and what physiological mechanisms mediate the response?
2. How does the animal's experience during growth and develoment influence the response?
ask about proximate causation : How a behavior occurs or is modified.
ask about ultimate causation : Why a behavior occurs in the context of natural selection.
3. How does the behavior aid survival and reproduction?
4. What is the behavior's evolutionary history?
