You might not think about your eyebrows much, but if they weren’t there, you’d definitely notice! So how did those patches of hair come to be above our eyes? Why can we wiggle them? What are they for? We asked Penny Spikins, Professor of Human Evolution at the University of York in the UK, to help us answer our questions.
If there’s a question that’s made you raise your eyebrows, we can help with that! Submit your Moment of Um question at BrainsOn.org/contact and we’ll find the answer.
