| '''Chemical evolution''' has two meanings and uses. The first refers to the theories of evolution of the ]s in the universe following the ] and through ] in ]s and ]s. | |||
| The second use of chemical evolution or '''chemosynthesis''' 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 ]. For that they are now called ]s. However only very basic organic building blocks were obtained. The challenge is getting complex molecules organized consistently. | |||
| The hypothesis is that simple chemical compounds could catalyze the creation of copies of themselves (somewhat similar to the formation of a ] or ]) in an environment rich with the necessary building block compounds or elements. As these ] "reproduce", they can be created with slightly different structures randomly, similar to biological ]s. Eventually these replicators would produce ]s. | |||

Chemical evolution may refer to:
- Abiogenesis, the transition from nonliving elements to living systems
- Astrochemistry, the study of the abundance and reactions of molecules in the universe, and their interaction with radiation
- Cosmochemistry, the study of the chemical compositions in the universe and the processes that led to them
- Evolution of metal ions in biological systems, incorporation of metallic ions into living organisms and how it has changed over time
- Gas evolution reaction, the process of a gas bubbling out from a solution
- Molecular evolution, evolution at the scale of molecules
- Oxygen evolution, the process of generating molecular oxygen through chemical reaction
- Stellar nucleosynthesis, the creation of chemical elements by stellar thermonuclear fusion or supernovae
