Humans are in a different position than all other organisms because we have such great communication skills. We don't need to physically adapt anymore. If a new ice age comes we'll build underground cities with great heating and everyone will live. Humans socially evolve, and this evolution happens much more rapidly than natural selection. So that's why we don't see any physical adaptation in humans anymore...and probably won't. Also, evolution has been duplicated millions times over in every species. Every species of the Galapagos islands is specifically adapted to that island. Greytone said it, and I'll say it again. Evolution is an observable fact.

...there was a time when the general scientific community KNEW that earth was the center of the universe. There was a time that they KNEW the world was flat.

Were have we ever observed mutations to be good? I mean a mutation by any other name is.. cancer

Everything that dies doesn't become a fossil. For an organism to stay preserved as a fossil it has to die in or around certain chemicals or rocks. This is a freak occurence and over time so many things have died that many fossils were left but this is only a fraction of what existed. But we have found enough fossils to connect the dots with great certainty. You don't need every last piece of the puzzle to know what it represents.

Scientists never knew the earth was flat. They thought it was because it made the most sense to them. They never observed the earth or had gathered facts to prove this like they have evolution.

Mutations are one of the 5 mechanisms of evolution along with natural selection (I think it's 5 if I remember correctly). Cancer is only mutations in genes regulating cell growth. Many other genes can be mutated to give an organism a greater chance at survival. I work with bacteria and when you put them under harsh conditions they begin to randomly mutate their own genes. Most of them die because they mutate genes at the wrong places, but by chance there's always a few cells that hit a certain gene that lets them live.
