abiogenesis
n 1: a hypothetical organic phenomenon by which living organisms
are created from nonliving matter [synonym: {abiogenesis},
{autogenesis}, {autogeny}, {spontaneous generation}]

Abiogenesis \Ab`i*o*gen"e*sis\, n. [Gr. 'a priv. bi`os life
ge`nesis, origin, birth.] (Biol.)
The supposed origination of living organisms from lifeless
matter; such genesis as does not involve the action of living
parents; spontaneous generation; -- called also {abiogeny},
and opposed to {biogenesis}.
[1913 Webster]

I shall call the . . . doctrine that living matter may
be produced by not living matter, the hypothesis of
abiogenesis. --Huxley,
1870.

  • Abiogenesis | Biology | Research Starters - EBSCO

  • Abiogenesis: The Origin of Life from Non-Living Matter
    The emergence of life from non-living matter, known as abiogenesis or spontaneous generation, stands as one of the most profound and challenging scientific questions Understanding how life arose on Earth requires unraveling complex chemical and physical processes that occurred billions of years ago This essay explores the historical context, scientific evidence, proposed mechanisms, and
