What Are The Advantages Of Lactase Persistence?

What Are The Advantages Of Lactase Persistence? Evolutionary advantages. Lactase persistence is a text-book example of natural selection in humans: it has been reported to present stronger selection pressure than any other known human gene. Why are some people lactase persistent? The apparent convergent evolution of lactase persistence among human populations is best explained as

What Is The Action Of Lactase?
