Generation of living entities from non-living chemical forms.

Abiogenesis is the idea that non-life can beget, i.e., parent living things, which is an idea implicit to that of the origin of life but does not likely occur in the modern world due to changes that have occurred in environmental and ecological conditions.

Abiogenesis is as may be postulated to have occurred in ancient environments over time spans that are much longer than that of the human lifespan.

Contrast with biogenesis as well as with spontaneous generation.
