Mutation isn't necessarily a permanent change. In many cases, mutations are not inherited by the mutant's offspring.

Evolution is simply change over time that leads to speciation via adaptation, nothing says that it has to be a 'better' form. There is a whole process of evolution called 'neoteny' that involves organisms reverting to more primitive child-like forms with more ancestral / larval traits rather than adult traits.
