1. The (supposed) origin or evolution of living organisms from lifeless matter without
the action of living parents; spontaneous generation (introduced by Professor
Thomas H. Huxley when addressing the British Association at Liverpool, September,
1870): "Our professor explained the theory of abiogenesis when we were learning about the evolution of species."
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 non-living 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."
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 for any abiogenetically spontaneous existence of life could possibly exist."

, abiogenic theories (pl) (nouns)
The theory that hydrocarbon deposits have a primarily non-biological origin.
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.

The non-living component of the total particulate matter suspended in water.
1. That which is devoid of life; non-living: "Geology is another example of abiosis or the study of non living matter."
2. Anything that is deficient or absent of life: "The primary goal of space exploration is to study the abiosis of other planets."
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. That which is harmful to or destructive of living organisms: "Water pollution creates an abiotic conditiion for aquatic plants and animals such as fish."
3. Relating to, or caused by, nonliving environmental factors: Many of the abiotic conditions such as temperature, water, soil, pH, salinity are destructive of living organisms."
