Document Summary
Behavior is an action as a response to a stimulus. Ecological and evolutionary basis of the behavior of organisms in response to particular stimuli from their environments. Research performed on vertebrates, arthropods, mollusks (nervous systems and skeletal muscular systems; they can process and respond rapidly to stimuli) Ask questions about genetics, hormonal signals, neural signaling, natural selection, evolutionary history, ecological interactions. Questions and test hypotheses and two levels: ultimate and proximate causation. Proximate and ultimate causation: proximate (mechanistic): how actions occur in terms of the neurological, hormonal and skeletal muscular mechanisms involved, ultimate (evolutionary): why actions occur based on evolution and history. Is the behavior adaptive, meaning it increases the species tness: ex. Spiny lobster: spend the day hiding in cracks of coral reefs but emerge at night to get clams, mussels, crabs. Proximate: they have receptors in their brain that detect changes in magnetic eld(use this to navigate on how eld changes in strength as they move around)
