The Importance of Specialized Mutation Systems in Mutation Bias Evolution
Theory doesn't depend on there being any kind of adaptive. Or like directed even would you? Right, exactly. There's no directed mutation.

So from my perspective, as someone who is really interested in the role of mutation in evolution, I really want to strictly distinguish between origination and fixation as two different steps in the evolutionary process.
