Blonde hair and blues eyes are both fairly recent mutations. I think you'd find some argument over whether this decreases the owner's chances of passing on his or her genes.
Methinks you have a twisted (go figure) idea of what a mutation actually is.
Penny ante science...do you ever play with a full deck---no wild cards/straight poker!
Nonsense. No one knows how blonde hair and blue eyes came about so saying they are mutations is just another evolutionist assumption. In addition to which, even if they were, it is not something that makes a species more complex or transforms it into something different. So even if it could be proven to be a mutation it would not be any sort of proof for evolution.
