Question

Why did 40% of the human population evolve to tolerate lactose?(1 point)

Lactose tolerance allows people to enjoy a wide variety of food, including milk, butter, ice cream, and cheese.

Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.
