	The second use of chemical evolution or ] is as a hypothesis to explain how ] might possibly have developed or evolved from non-life (see ]). Various experiments have been made to show certain aspects of this process, the first ones were done by ] in the 1950s. For that they are now called ]s. However only very basic organic building blocks were obtained. The challenge is getting complex molecules organized consistently.

As these ] "reproduce", they can be created with slightly different structures randomly, similar to biological ]s. Eventually these replicators would produce ]s.{{Fact\|date=October 2007}}
