You missed the point completely. It doesen't matter whether mutations are beneficial, neutral or detrminental, but that mutatations being the mechanism that drives natural selection makes no sense because the DNA molecule avoids mutations at all costs. A mutation only occurs when a gene expresses itself incorrectly, resulting in a new protein being synthesized than would otherwise be the case. So you are basically saying that what drives evolution are flaws in gene expression that the DNA tries to avoid at all costs? My point is that, since adapatations to the challenges of the natural environment are necessary for the DNA to survive but that the DNA does not encourage mutations, then there must be another mechanism that drives evolution, otherwise the DNA would encourage mutations, by causing as many errors in gene expression as possible and by making living organisms seek mates with the highest amounts of assymetries possible, which is the opposite of what happens. Understand now?

Sucky,
Your post is what scientists refer to as "NOT EVEN WRONG".
You need to understand the process before you critique some imagied flaw in the theory. Mutation is NOT always detrimental to an organism, nor is it the only method of adaption.
Sexual reproduction introduces huge VARIATIONS in the expression of genes (the genotype) in the phenotype (the body). Perhaps if you think in terms of variation instead of your mistaken concept of mutation you might better grasp the process.
Your argument that DNA avoids mutation "at all costs" is simply wrong, and countered with a singe word: cancer.
I think you have coflated one of the basic MECHANISMS of evolution (mutation) with the PROCESS itself.
Variation among a breeding species/population is caused by:
-mutations (deletions, transpositions, reversals, insertions of genes and gene groups)
-sexual blending of genes
Evolution itself is caused by:
-adaptive advatage
-reproductive advantage
-sexual selection
-population filtering (immunity; adaptability; "fitness" or aptness)
-species radiation
Believe me when I tell you that you misuderstand the basics sufficiently that you won't comprehend why you are mistaken... not without further study.
