2. The now discredited theory that living organisms can be spontaneously generated directly from nonliving matter: There are conflicts as to whether abiogenesis has any validity.
3. Spontaneous generation; the concept that life can simply arise spontaneously from nonliving matter by natural processes without the intervention of supernatural powers: There have been many throughout history who have strived to disprove the theory of abiogenesis.
abiogenetic (adjective) (not comparable)
Of or pertaining to that which does not result from the activities of living organisms: The former abiogenetic theory that plant and animal life can spontaneously arise from nonliving organic matter in a relatively short period of time has been rejected by just about everyone.
abiogenetically (adverb) (not comparable)
Relating to a condition of not being involved in or produced by living organisms: On TV, the biologists argued about how impractical it would be if any abiogenetically spontaneous existence of life could possibly exist.

According to this concept, such materials became trapped far below the earth's crust when the basic structure of the planet evolved, and have subsequently migrated into reservoirs and to the surface through openings in in the earth's crust.

Contrasted with the more generally accepted biogenic theory that hydrocarbon deposits derive from the remains of living organisms.

A process of degeneration of the nerve cells in the central nervous system.
abiophysiology (s) (noun), abiophysiologies (pl)
The study of inorganic processes or functions in living species: Abiophysiology involves research in the physical and chemical phenomena of living organisms as distinguished from the living matter; such as, organs, tissues, or cells.
abioseston (s) (noun), abiosestons (pl)
The non-living components of the total particulate matter that is suspended in water.
abiosis (s) (noun), abioses (pl)
1. That which is devoid of life; nonliving: Geology is another example of abiosis or the study of nonliving matter.
2. Anything that is deficient or absent of life: The primary goal of space exploration is to study the abioses of other planets.
abiotic (adjective) (not comparative)
1. A reference to the absence, or deficiency, of life: Is there such a thing as the abiotic existence of matter that is devoid of life or any specific life conditions?

Characterized by the absence of life, inanimate; such as, sand, gravel, stones, etc. all of which are abiotic.

2. Relating to, or caused by, nonliving environmental factors: Many of the abiotic conditions are destructive of living organisms; including temperature, water, soil, pH, and salinity.
