Document Summary
Intro: behavior, a behavior is an acion. It"s one that is carried out by muscles and these muscles are under the control of the nervous system: we can also think of it as a set of adaptaions. When we ask these quesions about the simulus, the physiological response, we are addressing here something called proximate causaion. What is happening now in terms of this behavior: the why quesions, why does this behavior aid survival and reproducion, these quesions are related to the evoluionary history. These quesions address ulimate causaion: example: bluegill sunish. Well, that"s not very reliable reliable factor: i. ii. And when the days are longer, these photoreceptors get simulated for a longer period of ime. And when they do, they trigger a series of physiological responses in the ish. This is the ime when breeding is most producive. The water is warm, and food is abundant.
