abiogenesis

[ab′ē·ōjen′əsis]
Etymology: Gk, a + bios, not life, genein, to produce
the idea that life can originate from inorganic, inanimate matter. Mid-twentieth century research by two University of Chicago chemists, Stanley Miller and Harold Urey supported the hypothesis that organic compounds essential to cellular life could be created under specific laboratory conditions. Also called spontaneous generation. Compare biogenesis. abiogenetic, adj.

abiogenesis

(1) Spontaneous generation. 
(2) The theory of spontaneous generation.

a·bi·o·gen·e·sis

(ā'bī-ō-jen'ĕ-sis)
Spontaneous origination of a living organisms directly from lifeless matter.

[G. a-, without, + bios, life, + genesis, formation]

abiogenesis

The theory of ‘spontaneous generation’-the long-discarded notion that living organisms can be formed from non-living matter. Louis Pasteur's work (see PASTEURIZATION) did much to overthrow this idea which was based largely on the observation that maggots often appeared on rotting meat.
