Answer to Question 1

Lactose intolerance is caused by a discontinued production of lactase in adults. The ability to
digest milk sugars is tied directly to coevolution, as those descended from dairying populations
have retained their ability to digest milk sugar through lactase persistence.

Answer to Question 2

True
