Answer 1

The correct response is: Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.

This is because in certain populations where dairy farming was prevalent, those individuals who could digest lactose into adulthood had increased access to a valuable food source, leading to better nutrition and survival compared to those who could not tolerate lactose.
