I don't know where you get this idea that I am a creationist, but if that makes you feel all fuzzy, then have at it.<quoted text>
Here it is again:
Not sure what you mean by the "reasons" for mutation. They simply happen. That's why you are born with around 125 to 175 mutations which are not shared by either of your parents. This is a normal part of human reproduction. So to me it sounds like you are thinking that evolution involves some kind of goal-direction. This is a common mistake made by creationists, which probably stems from their assumption that humans were always the intended goal since God made them that way.
I don't see any "goal" in evolution. In fact, from what I see it is more of regression than progression.
