 | | According to the more-popular soup theory, chemical evolution first took place in the upper atmosphere, where ultraviolet radiation from the sun could generate an assortment of simple and complex organic (carbon-based) molecules out of the basic components of the atmos- phere. |
 | | Via the ultraviolet radiation, light- ning, volcanic action, and other forms of heat and energy, this soup was able to slowly combine the organic molecules into ever more com- plex forms: first simple amino acids, then organic macromolecules, then single-strand RNA molecules, and finally simple viruses. |
 | | This allows them to be easily washed away by the sea, forming a primordial soup not of basic simple mole- cules, but of the far more complex and already evolved RNA macromole- cules and possibly even viruses. |
