All mutants die out? You haven't been looking into the matter again, only into your little websites.
The rule is that only a few survive, and a fraction of those result in speciation, i.e. the appearance of a new species that is unable to mate with its ancestors. Speciation is best observed in insects because of their high rates of reproduction. Novel genetic material is created by non-fatal mutations all the time.
As for mutants dying out, just ask bacteria. Mutation is their very strategy of of survival.
It is a pity that you stick to mythology. Many creationists at least accept the basics of evolution because their own world view and concept of science wouldn't make sense without it.
