Knowledge check
Q1. What is the primary mechanism of evolutionary change according to Darwinian theory?
- A. Mutation
- B. Natural Selection ✓
- C. Genetic Drift

- B. When the benefit to the recipient is low
- C. When the relatedness between the altruist and recipient is high ✓
- D. When the altruist is not related to the recipient
Why: Hamilton's rule suggests that altruism is more likely when the relatedness between the altruist and the recipient is high, making the behavior evolutionarily favorable.
Q5. Which of the following is an example of kin selection?
- A. A bird feeding a unrelated orphan
- B. A human helping a sibling in need ✓
- C. A wolf attacking another wolf from a different pack

- A. She is the only reproductive individual ✓
- B. She performs all tasks in the colony
- C. She is the smallest member of the colony
- D. She does not interact with other members
Why: In many eusocial insect colonies, the queen is the primary reproductive individual, laying eggs and ensuring the continuation of the colony.
Q5. What is the evolutionary advantage of eusociality?
- A. Increased individual survival
- B. Increased genetic diversity
- C. Enhanced reproductive success of the colony as a whole ✓
- D. Reduction in predation
Why: Eusociality enhances the reproductive success of the colony as a whole by ensuring the survival and propagation of the genes of the queen and other related individuals.

- A. Epigenetics
- B. Heritability
- C. Gene-environment interaction
- D. Behavioral genetics ✓
