I bestræbelserne for at forklare fremkomsten af biomolekyler og de første levende celler, har det vigtige spørgsmål været om det var peptider først, DNA først eller RNA først. I 2015 se svaret ud til at være peptider og RNA<ref>[[http://www.sciencealert.com/scientists-may-have-worked-out-how-life-evolved-from-building-blocks-on-earth Scientists may have worked out how life evolved from building blocks on Earth.
