Question
A) Why did 40% of the human population evolve to tolerate lactose? (1 point)
Babies rely on milk to survive, so they need to be able to tolerate lactose.
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.
People who have an intolerance experience physical pain, so a tolerance evolved to avoid that.

The most accurate reason for why 40% of the human population evolved to tolerate lactose is:
**Within cultures that rely on milk-producing animals, individuals who tolerated lactose had a survival advantage.**
This is because individuals who could consume milk without adverse effects were able to access a valuable source of nutrition, leading to better overall health and increased reproductive success in those cultures where dairy was a staple.
