Questions

  1. 1.

    In certain social animal species, an individual incurs an immediate fitness cost to assist an unrelated group member, with the expectation that the recipient will return the assistance in future encounters. Which concept best explains the evolutionary maintenance of this cooperative behavior?

    • A) Kin selection
    • B) Fixed action pattern
    • C) Competitive exclusion
    • D) Reciprocal altruism
  2. 2.

    In many flocking birds and schooling fish, individual animals reduce their personal scanning time as group size increases, yet the group as a whole detects approaching predators more rapidly. Which concept best explains this collective anti-predator advantage of social group living?

    • A) The many-eyes hypothesis
    • B) The dilution effect
    • C) The selfish herd effect
    • D) Competitive exclusion
  3. 3.

    In social insects such as honeybees (Apis mellifera), a returning forager performs a waggle dance primarily to communicate which of the following pieces of information to hive members?

    • A) The distance and direction to a distant food source relative to the position of the sun
    • B) The chemical composition and sugar concentration of a newly discovered flower patch
    • C) The physiological health and reproductive fertility of the resident queen bee
    • D) The exact size and flight path of an approaching aerial predator
  4. 4.

    In many social animal species, conflicts over mates or territory are resolved through ritualized agonistic displays rather than lethal combat. What is the primary evolutionary advantage of resolving disputes through these ritualized behaviors?

    • A) It ensures that subordinate individuals gain equal access to reproductive opportunities within the group.
    • B) It completely eliminates the expenditure of metabolic energy during competitive social interactions.
    • C) It permanently prevents future challenges to the established social hierarchy by younger group members.
    • D) It minimizes the risk of severe physical injury or mortality while determining resource access and social rank.
  5. 5.

    Which evolutionary concept best explains how altruistic behaviors, such as sterile worker insects caring for their siblings rather than reproducing directly, can be favored by natural selection?

    • A) Competitive exclusion
    • B) Inclusive fitness
    • C) Disruptive selection
    • D) Character displacement
