Grazing Rites

What evolutionary process do eyebrows serve? Do they keep incredibly small debris from falling down our face into our eyes? Do they keep the sun from getting in our eyes at exactly high noon? Would that matter to anyone but a cowboy gunslinger?

Now I know not all evolutionary traits serve a survival purpose. Often birds with brighter plumage will attract more mates and thus pass that trait on to future generations but the bright colours only make them more visible to predators. But if eyebrows fell into this category wouldn’t bushy eyebrows and unibrows be considered more attractive? So that can’t be it.

Besides even those silly attraction things often have evolutionary support like those bright colours being a sign of good health or large sexual organs a sign of good breeding potential.

Perhaps they are evolutionary holdovers from our monkey days but why just the eyebrows? Why two lines above your eyes? There must be a reason.

Even creationism doesn’t have an answer for this. If we were made in God’s image that’s just passing the buck, the question then becomes why does God have eyebrows?

Anyone?
