Ok theres a fringe hypothesis that at some point in our evolution one of our ancestors spent a bit of time in the water. It's known as the Aquatic Ape Theory or ATT for short, but in keeping with scientific norms it should be called a hypothesis and not a theory as it is far from an established theory. I know very little about serious biology but I know more than most people, which isn't saying much at all, hell I'm not even sure if "most" know that evolution is real. Anyway I heard about this theory, er hypothesis, at some point and found it interesting. It seemed to explain a few odd things, such as why aren't we covered in hair like other primates? From the view of a layman it seemed possible and interesting. But it appears that from the view of someone who knows something about biology it's not a very convincing argument at all. This is how and why science works, anyone is welcome to come up with a hypothesis, and anyone is welcome to try to prove it wrong. Contrary to what the haters think taking down an established theory is what makes the greats the greats. You've heard of people like Einstein and Newton right? It's important to note that Einstein was not a famous scientist who proved Newton wrong, he became a famous scientist BECAUSE he proved Newton wrong. When he proved Newton wrong the second time he was famous.
Anyway the point is that if you are going to venture into science then you'd better have skin thick enough to stand some criticism because it's going to happen, thats how science works, its why science works. I bring this up once again because if I get to it this will be an important part of the next post.
