Evolution A Mistake

I really like what Dawkins says about evolution being a mistake. If it wasn't for all the random mutations and mistakes during copying, humans would not be here right now. When you think about it like that, it is weird to think that we started off as simple replicator cells.
He also says that no species actually wants to mutate, which is very true. All of this really makes you think about everything that could've gone wrong throughout history. Imagine of all of these mutations would have never existed. What if these replicator cells got the copying process flawlessly correct on the first try? Humanity, then, is the result of a million mistakes.
