abiogenesis

n. creation or evolution of an organism from lifeless material, spontaneous generation (Biology)

This article focuses on the history of thought regarding abiogenesis (the spontaneous generation of life from non-living sources). For abiogenesis as a scientific study, see main article, Origin of life. For the theory of abiogenic petroleum origin see abiogenic petroleum origin. Abiogenesis (Greek a-bio-genesis, "non biological origins") is the formation of life from non-living matter. Today the term is primarily used to refer to hypotheses about the chemical origin of life, such as from a 'primeval soup' or in the vicinity of hydrothermal vents, and most probably through a number of intermediate steps, such as non-living but self-replicating molecules (biopoiesis). The current models of abiogenesis are still being scientifically tested.
