What is behaviour?
Behaviour is the sum of an organisms responses to an external and internal stimuli
How are actions ( behaviour) carried out?
by muscles under control of the nervous system
stimulus-> _ -> _ -> behaviour
nervous system, muscle glands
Example of a behaviour
animal using its throat muscles to produce a song or releasing a scent to mark behaviour
Proximate causation explains
how a behaviour occurs
Ultimate causation explains
why a behaviour occurs
Example of ultimate causation questions
Evolutionary history for a behaviour. Ultimate causation is the “real” reason something occurred, and is often referred to as the evolutionary explanation for something
Example of proximate causation questions
Proximate causation is an event that is closest to, or immediately responsible for causing, some observed result.
what is physiological stimuli and an example

example= increased daylight triggers release sex horomone
What is Behavioural stimuli and an example
Closing the eyes in response to bright light is
what do systemic reasons explain
why a cicada sings…. bcs members of cicada lineage usually sing
what do evoultionary reasons explain
bcs singing increases fitness
what is a fixed action behaviour
an unlearned behaviour that contiues until completed
example of fixed action pattern
observer noticed that male sticklebacks behave aggressively towards red items that pass like a truck
the red item that prompted this behaviour is a _ bcs
a sign stimulus, bcs it triggered a fixed action pattern (FAP) in an animal
environmental stimuli not only trigger behaviours but also provide
cues to help them carry behaviours out
