spontaneous generation

spontaneous generation

* * *

also called  Abiogenesis,  

      the hypothetical process by which living organisms develop from nonliving matter; also, the archaic theory that utilizes this process to explain the origin of life. Pieces of cheese and bread wrapped in rags and left in a dark corner, for example, were thus thought to produce mice, according to this theory, because after several weeks, there were mice in the rags. Many believed in spontaneous generation because it explained such occurrences as the appearance of maggots on decaying meat.

      By the 18th century it had become obvious that higher organisms could not be produced by nonliving material. The origin of microorganisms such as bacteria, however, was not fully determined until Pasteur proved in the 19th century that microorganisms reproduce. See also biopoiesis.
