Why the evolution of Beards?

What are the possible theories on the evolution of beards? Its significance to beauty may be culturally biased as some cultures have revered it, others find them primitive.

It must have had some significant advantage as it consistently appears in most populations of our species and our closest evolutionary links don't have mustaches or full facial hair. Why did we select for it or did it add any advantage? Does advertising or film have anything to do with why we don't prefer facial hair anymore?

    How come you ignore species of other primates having facial hair in male, even male goats (not being primate) have that.

    Hope more questions will not come about differences between other organs of male and female :)

    A mustache was quite popular and sexy before the 70's or 80's but now its tilted the other way. There must be some root causality to such trends?

    I think that facial hair is useful for quick distinction amongst a crowd.

    Jun 22 2011: Well, I think a small mustache and beard are marks of manhood. My husband has both and I think he looks great. To me a sign of virility. As for women that is some kind of natural mistake.
