Why is skin darker around the pubic region?

I am a male and I know its not true for everybody. I also know its true for some females as well (I know my freinds have referred to it as the girl having "roast beef" downstairs). Can anyone explain it?

There is an increase of the melanin cells in that region for some people, it is just a genetic variant that doesnt really have a purpose that i remember learning about. Some theorize it was to help protect the more sensitive skin of the area from the effects of the sun when exposed.
