As I stare at the bathroom, I notice something that I have never pertained any attention to. Something that has never gained any interest, in my aspect. Something that’s just…there… but never noticed, kinda like our belly button. Just on our face. And no, I do not have a naval on my left cheek.

Eyebrows. Eyebrows. Eyebrows. What purpose do they really serve us? Why do we have hairs sprouting above our eye sockets? What necessary biological function, do they really serve?

Of course, they provide the transfer of emotions (such as arching your eyebrows ti represent anger, annoyance, etc) in our culture and may provide as some form of beauty. But, I’m speaking of why physiological function did they have for our ancestors, or us today? After all, I don’t see the eyebrow as a necessary body attribute that contributes to the survival of man.

But, Howstuffworks just has prove me wrong:

“We know that eyebrows help keep moisture out of our eyes when we sweat or walk around in the rain. The arch shape diverts the rain or sweat around to the sides of our face, keeping our eyes relatively dry. The most obvious advantage of this is that it lets us see clearly when we’re sweating a lot or out in the rain. Without eyebrows, getting around in these conditions is a little more difficult.”

“There are a number of ways these qualities might have helped early man survive. Being able to see more clearly in the rain could certainly help you find shelter, and there are several circumstances when keeping the sweat out of your eyes could save your life. If you were trying to outrun a predator, for example, it’s a good bet there would be a lot sweat running down your face. If all that sweat flowed right down into your eyes, you wouldn’t be able to see that well, and your eyes would be irritated, which would certainly impair your ability to escape! Because of this slight survival advantage, nature would most likely select for humans with eyebrows over humans without eyebrows.” - Howstuffworks.com

I’ve taken them for granted all this time?! The next time I run from a man-eating dinosaur, I will surely keep my eyebrows in good condition for absorbing sweat.

I will never doubt the Holy eyebrow, any longer. *bows*
