1
Q

Proximate

A

immediate sequence of physiological effects that lead to behaviour— how?

2
Q

Ultimate

A

adaptive value or evolutionary origins of the adaptive behvaviour– why?

3
Q

Evidence for genetic component to behaviour: deprivation experiments

A
  • eliminating the learn component through isolation of the subject
    ex. squirrels burying
4
Q

Fixed Action Pattern

A

pattern that appears essentially complete and is played out to completion once activated by a simple sensory cue, predictable, first performed without training

5
Q

Evidence for a genetic component to behaviour: selection experiments

A
  1. hold environment constant
  2. all participants learn the same thing
  3. measure phenotype
  4. breed individuals with extreme phenotypes
  5. measure phenotype in next generation
6
Q

Evidence for a genetic component to behaviour: crossing of genetic strains

A

ex. crossing of non-hygienic bees and hygienic bees affects their role in the hive

7
Q

Evidence for a genetic component to behaviour: Molecular Genetics

A

ex. mono amine oxidase mutation: neurotransmitter not broken down normally = hyper agressive disorder
