Yes. This one is so obvious it’s a mystery to me why many can’t see it. Mutations accumulate, they’re subject to natural selection, so their functions are selected and their information accumulates. The genetics of replication is EXACTLY the kind of thing that would produce a gradual increase in information, genes, functions, and so on.
Mutations even come in exactly the types required to sample the space of genetic solutions: Duplications, rearrangements, transpositions, substitutions, insertions, deletions.
