WebOne possibility is that the first life forms were self-replicating nucleic acids, such as RNA or DNA, and that other elements (like metabolic networks) were a later add-on to this basic system. This is called the genes-first hypothesis ^ {14} 14. Webthe lowest forms and as we ascend the scale is very quickly lost.
