Why do we have eyebrows? I understand most other hairs have the use of blocking something, like dust in our nose(i may be wrong on that as well) but what is the use of eyebrows?
In: Biology
They can help us see in the rain or when we’re super-sweaty, by diverting the flow of water running down our heads and keeping it out of our eyes. Think of them as storm gutters for your forehead.
They’re also a pretty important part of the expressive gestures we make with our faces, so there might be some selection pressures which made them more prominent too.
