To start, I became lactose intolerant many years ago and it was a very difficult transition as I live in a society where dairy products are primarily all the popular foods that I like to eat. Like ice cream. Imagine being at a birthday party faced with delicious looking ice cream cake while young with no magical lactase pills.

As I got older, I found out that a great deal of the world population is lactose intolerant after a certain age. I learned that most cultures that have very low dairy consumption are predominately lactose intolerant while those that, even recently, consume more dairy products become lactose tolerant.

The science of this is that there is a mutation on chromosome 2 gene which eliminates the shutdown in lactase production after the suckling years. While I found this out years ago to help me accept my inferior ability to handle that spicy milk, I always wondered about actual statistics regarding people by region. I found this on Wikipedia to be of interest.

An anecdote here involves my Native American friend mocking me for becoming lactose intolerant only for him to become lactose intolerant after several months of joking about my condition.

After a little thought, isn't lactose tolerance a simple explanation for people regarding recent evolutionary proof in human beings? Why is it that this is never brought up in debates or arguments with those that choose to fail to grasp the idea or ignore evolution? Is this not a stopper in support for evolution during those ridiculous debates?
