RNA world is a hypothesis that is heavily supported but not without its flaws. These flaws surround the stability and creation of RNA. To solve these problems a 'Pre-RNA World' was introduced. The hypothesis suggests that before RNA there was a much simpler molecule that still had "both catalytic activity and information sotrage capabilities" [1].
