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.
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.

abioseston (s) (noun)

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.
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.
