RNA alone is a good enough self replicating life form that arose first before we the rest of the cell machinery. This would be the most extreme form of the RNA world hypothesis. There is no need for anything else to evolve to claim that life has arisen.
OK, but how does this evolve into a bacterium? Won’t it evolve into a local maximum of RNA enzyme replication efficiency and stay there?
