...so? That's a trivial detail, it's just how the mechanism of how the genome is added to. Whether there is even a difference between 'adding' and 'replicating and changing' in the first place, that is. By your definition of 'adding to the code', a group of new bases would have to appear out of nowhere and physically wedge themselves into the DNA... and that's never going to happen. Basically, regardless of the mechanism, the code is definitely being added to. It codes for a greater number of amino acids so it has therefore been added to.
