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 Mutation Causes Lactase Persistence In Humans? Within European and populations of European ancestry, they are almost entirely correlated with the presence of the −13,910 C/T mutation in the enhancer region of the lactase gene (LCT). Is there only one mutation that causes lactase persistence? Some humans, however, continue to produce lactase throughout adulthood, a
