Animal behavior:
Morphology:
Physical structure of an animal
Physiology:
Function of morphology
Behavior:
Action in response to a stimulus
Adaptive behavior:
Behavior that increases the animals reproductive success either directly or indirectly
Non-adaptive behavior:
Behavior like altruism that doesn't contribute to reproductive or survival success
Proximate causes:
Event closest to or responsible for a happening.
For behavior, the proximate causes are what stimulus causes the behavior and what the animal does in response to the stimulus
Ultimate causes:
The real reason something happened.
Foraging:
Behavior associated by eating food
Optimal foraging model:
Foraging model providing the most food for the least work or most net energy
Altruism:
Altruism can evolve when "Benefit of a behavior > Cost on individual"
Inclusive fitness:
Expected fitness of an individual includes the direct fitness or the personal fitness and indirect fitness which depends on who it interacts with socially
