Learned and innate behaviour Flashcards
What does ‘innate behaviour’ mean?
Genetic influences
How do genetic differences lead to a difference in behaviour?
- DNA regulates transcription products -> protein synthesis -> lots of hormonal control
- different genes have been shown to influence behaviour
Differences in what complex, can lead to a difference in odour production?
Major histocompatibility complex
What stops storm petrels from breeding together?
Do it by recognising the MHC difference in odour which leads to odour based mate choice for optimum immune system function
How do sweat bees only allow their kin into their nest burrows? How does this impact them for future generations?
Learn odour of their nestmates. These odours are heritable meaning some bees may recognise odours of someone they have never met before, keeping non-kin out
How do honey bees determine which bee is their next queen bee?
Queen lays loads of eggs, larvae are fed with royal jelly, ones fed for longer develop into a queen.
Environmental differences determines the developmental behaviour
What is habituation?
Reduced response across repeated exposures to a stimulus
What is neophobia?
Brief aversion to new objects - only lasts a few minutes
What is dietary wariness?
Prolonged aversion to novel food
How can environment influence dietary wariness?
Can be modified by animals experience with food e.g., chicks brought up trying novel food a lot shouldn’t have this problem
What is social learning?
Changed behaviour in response to to observing others
What is cultural transmission?
Transmission of behaviour within and between social networks
What is horizontal and vertical transmission?
Vertical - transmission down matrilines
Horizontal - transmission between peers in different matrilines
