Found what I was looking for. Keeping old biology notes/packets are handy, yeah? I added a few words of my own. Animal behavior can be inherited through genes (innate behavior), or it can be learned through interactions with the environment. Behavior that is influenced by genes (innate) is molded by natural selection and other evolutionary forces. As a result, most genetically based behaviors should increase the fitness or reproductive success of the individual. The study of behavior that seeks to explain how specific behaviors increase individual reproductive success is called behavioral ecology. - Instinct is behavior that is innate, or inherited. - Fixed action patterns are innate behaviors that follow a regular, unvarying pattern. They're initiated by specific stimulus. Typically, the behavior is carried out to completion - even if the original intent of the behavior can no longer be fulfilled. - Imprinting is an innate program for acquiring a specific behavior, only if an appropriate stimulus is experienced during a critical period. Once acquired, the behavior is irreversible (meh, never say never! And science.) Okay . . . I flipped the page and there are like 6 more kinds of behavior and/or learning. I don't feel like typing all of the explanations. - Associative learning; trial-and-error learning; spatial learning; habituation; observational learning; insight. Some behaviors that appear to be learned may actually be innate behaviors that require maturation (or, vice-versa, it'd be easy to mistake for the other). For example, birds appear to "learn" to fly by trial-and-error, or by observation. However, if birds are raised in isolation, they will fly on their first try, if they are physically capable of flying. In general, inherited behaviors and learning capabilities of animals have evolved because they increase individual fitness (and, in turn, increases chances of survival and reproduction). In relation, there are also various types of movement; directed, undirected - migration, movement toward light, scent; communication, social behaviors, etc.
