RNA world hypothesis The RNA world is a hypothetical stage in the evolutionary history of life on Earth, in which self-replicating RNA molecules proliferated before the evolution of DNA and proteins. The term also refers to the hypothesis that posits the existenc ...

, and held that the spontaneous emergence of a molecule as complicated as RNA is highly unlikely. Instead, he proposed that life arose from some self-sustaining and compartmentalized reaction of simple molecules: "metabolism first" instead of "RNA first". This reaction would have to be able to reproduce and evolve, eventually leading to RNA. He claimed that in this view life is a normal consequence of the laws of nature and potentially quite common in the universe.Alvin Powell
