  • 1. 
  • 2. 
    Describe two ways to test if behaviour can be inherited. For each test, provide a real-world example
  • 3. 
    The best decision often depends on conditions relating to an animal and its environment. Hence, there is no "best decision." If this statement is true, think of a real-world example to prove this statement
    • A. 

      True

    • B. 

      False

  • 4. 
    Behaviour does not fossilize. However, comparison among species can suggest a possible sequence behavioural evolution. If this is true, think of an example which may help to prove this statement. 
    • A. 

      True

    • B. 

      False

  • 5. 
    Natural Selection has resulted in behaviours that help animals to survive and reproduce
    • A. 

      True

    • B. 

      False

  • 6. 
  • 7. 
    Describe two costs of living in groups. For each description, provide an example
  • 8. 
    Describe the term 'selfish geometry' and provide a real-world example of this behaviour
  • 9. 
    Describe two benefits of living in a group which have not been discussed in previous questions. Provide an example for each description.
  • 10. 
    The process of natural selection means that animals ARE selected to act “for the good of the species”
    • A. 

      True

    • B. 

      False

  • 11. 
    Kin selection favours behaviour that spreads genes through any kin, not just offspring
    • A. 

      True

    • B. 

      False

  • 12. 
    According to Hamilton's rule:
    • A. 

      Natural selection favors altruistic acts when the resulting benefit to the beneficiary, corrected for relatedness, exceeds the cost to the altruist.

    • B. 

      The effects of kin selection are larger than the effects of direct natural selection on individuals.

    • C. 

      Altruism is always reciprocal.

    • D. 

      Natural selection does not favor altruistic behavior that causes the death of the altruist.

    • E. 

      Natural selection is more likely to favor altruistic behavior that benefits an offspring than altruistic behavior that benefits a sibling.

  • 13. 
    Altruistic behavior __________.
    • A. 

      Never occurs in natural populations

    • B. 

      Is expected when the species as a whole benefits from it

    • C. 

      Occurs only when closely related individuals benefit from it

    • D. 

      Is expected when it increases the long-term inclusive fitness of the altruists

    • E. 

      Is expected when there are plentiful resources to share

  • 14. 
    Which of the following statements best defines an altruistic act?
    • A.

    • B. 

      It immediately benefits another individual at some cost to the performer.

    • C. 

      It immediately benefits the performer and imposes a cost on another individual.

    • D. 

      It imposes a cost on the performer and the other individual.

    • E. 

      It imposes a cost on the performer without benefiting another individual.
