It is actually a genetic variant that allows adults to continue to produce lactase, the enzyme which breaks down lactose.

What percentage of the world is lactose intolerant?

While most infants can digest lactose, many people begin to develop lactose malabsorption—a reduced ability to digest lactose—after infancy. Experts estimate that about 68 percent of the world’s population has lactose malabsorption. Lactose malabsorption is more common in some parts of the world than in others.
