Why do you have eyebrows?

You’ll think twice about plucking your eyebrows when you discover their important role, says Greg Foot.

They are one of the most expressive parts of our bodies. With your eyebrows, you can communicate your feelings to other people whether you’re quizzical or angry. But is that their only purpose?
Over millennia, we have lost lots of body hair. So it’s curious that hair still remains on our brows. As the Head Squeeze team explains, the main job of the eyebrows is as a special form of protection for the eyes.
In fact, their job so important that some researchers believe if we didn’t have them, we’d have evolved some other facial feature to do the same task – so if it wasn’t for eyebrows, we’d look a lot weirder.
