Primordial soup

A liquid rich in organic compounds and providing favorable conditions for the emergence and growth of life forms. The organic compounds in the primordial soup, such as amino acids, may have been produced by reactions in the Earth’s early atmosphere, which was probably rich in methane and ammonia. The complex self-replicating organic molecules that were the precursors to life on Earth may have developed in this primordial soup. Soviet biologist Alexander Oparin in 1924 proposed the theory of the origin of life on Earth through the gradual chemical evolution of molecules that contain carbon in the primordial soup.
