Terry,
If evolution depends on mutations please to explain to me how then it postulates progress? You are assuming that good mutations will outnumber or outweigh bad mutations. Is that the observation of Science, or is it a matter of faith, because is the only mechanish that is available to make the theory reasonable?
It must go something like this - All or almost all the mutations we observe are BAD, but there must have been good mutations at some time in the past because there has been progress from the single cell to the complex of billions of cells with specialized that make up the human body. Oh and yes, where did the single cell come from? The evolution of the woodpecker has always been somewhat of a puzzle to me. Think of all the millions, even billions of woodpeckers that beat their brains out and died before that magical day when the shock absorbing material in the woodpeckers head was complete and the organism was able to both eat and live...
