primordial soup  (prī-môr'dē-əl) Pronunciation Key
A liquid rich in organic compounds and providing favorable conditions for the emergence and growth of life forms. Oceans of primordial soup are thought to have covered the Earth during the Precambrian Eon billions of years ago. 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. |
