Let me point out that when you said: I laughed at you. And I absolutely disagree with you on that point, and it would take someone without a clue as to what a mutation is, or how it works in evolution, to say it. I'm calling you out on your ignorance. Anyhow, it seems you've wised up to the fact that mutation is very pertinent to evolution and genetic variation, and that evolution at its very core is a mutation of species - changes in their DNA - and that mutations are purely random. I don't feel like discussing this anymore, I've got too much to do. You all take care now. It's true that mutations are random. What does that gain you? Advantageous mutations mean that individual is more likely to reproduce and pass that mutation onto it's offspring. This is the heart of evolution.
