I remember learning in my science class about evolution. I think it is interesting that so many people don't believe in evolution. It is obvious and impossible to ignore that things evolve. Even humans evolve over time. That's why we have different skin colors. It all depends on where our original civilizations evolved from. The more sunlight there is, the darker our skin is. I am very white. It is almost disgusting. Maybe my body will learn to evolve if I go outside more. I guess that is also why we tan. Evolution is an interesting thing. Maybe one day I will be able to study and understand it just a little bit more.
