- Animal behavior includes all the ways animals interact with other organisms and the physical environment.
- Behavior can also be defined as a change in the activity of an organism in response to a stimulus, an external or internal cue or combo of cues.
- To fully understand a behavior, we want to know what causes it, how it develops in an individual, how it benefits an organism, and how it evolved.
- Some behaviors are innate, or genetically hardwired, while others are learned, or developed through experience. In many cases, behaviors have both an innate component and a learned component.
- Behavior is shaped by natural selection. Many behaviors directly increase an organism's fitness, that is, they help it survive and reproduce.
