11. Why was it important for both populations to retain the ability to digest lactose into adulthood when all other mammals lose the ability as they become adults?
12. What evidence was provided to support this coevolution theory of the same gene mutation in populations so distant from each other?
13. Explain the selective advantage of lactase persistence in populations 10,000 years ago, and how that contributed to its increase in modern-day populations.
14. From what you learned about gene-culture coevolution, do you believe lactase persistence will increase or decrease in future populations? Explain your answer with supporting evidence or ideas.
