We are raising a few eyebrows with this awesome question from Sam Lane which is Why do we have eyebrows? Yes, those two bits of hair that sits just above your eyes that are preened, picked, plucked, and manicured. Why do we have them?

In a nutshell, as homo sapiens we had hair all over our face and as evolution progressed we lost that hair, but the hair around our eyebrows just hung on. Don't pluck too much as those eyebrows are not just an evolutionary hangover they also protect your eyes from sweat and dust. Yuk!

To find out how far we've come check out James' vid on evolution http://www.youtube.com/watch?v=KVy5aO2DHmI&list=PLMrtJn-MOYmfqNgyPxx6NYMZnd25y4shc&index=35

Or for more biology questions have a look at Greg's vid on why we have fingernails http://www.youtube.com/watch?v=ytHsDlmAo0g&list=PLMrtJn-MOYmcMLEnLKQjjxJqled29hSLB&index=9
