  skos:definition "Chemical evolution is the process of the synthesis of biochemically important molecules starting from simple molecular building blocks, such as water (H20), nitrogen (N2), carbon dioxide (C02), and hydrogen sulfide (H2S), under plausible primordial conditions that governed the prebiotic Earth. It describes a process of increasing complexity from simple inorganic compounds toward first simple organic compounds that in turn formed biochemically important structures for a first living system.
