Eyebrows!

Hey guys, it's Adventure Van here with a blog about Eyebrows. We know the reason we have eyebrows. It helps keep stuff out of our eyes, like dust. But the question is, why has mankind got such... expressive eyebrows? We can use them to signal happiness, and discomfort, and tons of other emotions. We can use them for secret codes and signs, even. But why are they so maneuverable? Simple. It was so that we could survive in a changing world. As social interaction became more and more of a big deal, the more information you could get out during a conversation, the less time had to be spent on it, and more time running from predators, catching prey, and later farming and building. Our eyebrows evolved so we could show reactions and interact. It also helps that people with more agile eyebrows were better at getting mates, letting those genes carry on.
