Lecture 21

Question 1

Proximate

Answer 1

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

Question 2

Ultimate

Answer 2

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

Question 3

Evidence for genetic component to behaviour: deprivation experiments

Answer 3

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

Question 4

Fixed Action Pattern

Answer 4

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

Question 5

Evidence for a genetic component to behaviour: selection experiments

Answer 5

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

Question 6

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

Answer 6

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

Question 7

Evidence for a genetic component to behaviour: Molecular Genetics

Answer 7

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