What do you, me and every other person on Earth have in common? I won't make you guess, because we all have a lot more in common than we think we do. No matter how different we might seem from each other, we're all part of the same species: homo sapiens. And that means that we all have ancestors in common. We know what Neanderthals look like, but it's a different story for their recently discovered cousin, the Denisovans. Some scientists have just made a pretty good guess about what the Denisovans looked like.
