Life has been on the planet for an estimated (Outside edge) 4 and a half BILLION years.
That is a 'Long' time. In that time the surface of the planet has, litterally, reshaped itself through continental plate tectonics.
So, pretty much every place on the planet has been every where else...
Not at work.
Well, I think the fact that there are marsupials in the Americas goes with your point about shifting surfaces. They're not all isolated to Australia, presumably because of those shifts. However, I think this overall idea of spreading goes against your point. Competition, it seems to me, has a greater effect within such pristine pockets. By restricting life to smaller location, resources are limited, and it makes sense for competition to have a more magnified effect. But if life is being spread all over, it allows for greater resources, and less competition.
The idea of DNA eating RNA is still a bit obscure. I've forgotten how DNA replicates; but in terms of doing anything else (primarily building proteins) it needs RNA to do it. Perhaps there is some bacteria that skips RNA and can go from DNA to protein; but in our bodies RNA is equally important to DNA.
