I think the data better supports that DNA pre-codes for DNA changes. I suggest that speciation is not because mutations alter DNA serially, and then express, and then are selected. It is because the parent species has a propensity to alter itself into the daughter species. This essentially puts all of the code for the common ancestry into the first life form. A little tough to accept, but I think this is the most consistent with the extant data. It does (certainly) make the abiogenesis process that nuch more difficult, but it is what it is.
I ran a whole thread on this topic a couple years. The title was something like "statistical/probabilisitic issues with speciation".
