	Abiogenesis - LoveToKnow 1911
		ABIOGENESIS, in biology, the term, equivalent to the older terms "spontaneous generation," Generatio aequivoca, Generatio primaria, and of more recent terms such as archegenesis and archebiosis, for the theory according to which fully formed living organisms sometimes arise from not-living matter.
		Aristotle explicitly taught abiogenesis, and laid it down as an observed fact that some animals spring from putrid matter, that plant lice arise from the dew which falls on plants, that fleas are developed from putrid matter, and so forth.
		The refutation of abiogenesis has no further bearing on this possibility than to make it probable that if protoplasm ultimately be formed in the laboratory, it will be by a series of stages, the earlier steps being the formation of some substance, or substances, now unknown, which are not protoplasm.

	Abiogenesis and the Origin of Life
		It is a common belief among today's scientists that life's origin was naturally based, and therefore abiogenesis (life from non-life) must have occurred.
		Likewise all organisms on earth were constructed with the same common design, which to some indicates a common ancestry.
		Abiogenesis is a theory that attempts to explain the origin of life through random natural processes, and is taught as a regular component of evolutionary biology.

	Abiogenesis
		Aristotle explicitly taught this form of abiogenesis, and laid it down as an observed fact that some animals spring from putrid matter, that plant lice arise from the dew which falls on plants, that fleas are developed from putrid matter, and so forth.
		The first step in the scientific refutation of the theory of Aristotelian abiogenesis was taken by the Italian Francesco Redi, who, in 1668, proved that no maggots were bred in meat on which flies were prevented by wire screens from laying their eggs.
		It was due chiefly to Louis Pasteur that the occurrence of abiogenesis in the microscopic world was disproved as much as its occurrence in the macroscopic world.

	Abiogenesis
		While spontaneous generation proposed the emergence of a complete, complex cell or organism from organic molecules in one huge jump, abiogenesis draws from gradualism, where the original life forms were much simpler than modern cells and only gradually evolved their present-day form of complexity.
		Thus, abiogenesis not only places the spontaneous generation of life far in the past, but the life that is generated was supposedly much simpler, thus easier to generate spontaneously.
		Essentially, abiogenesis is an exercise in reductionism whereby we attempt to a) conceptualize life in progressively simpler and simpler components and b) imagine that history reversed this process of conceptualization, building up layer and layer of increasing complexity.

	Britain.tv Wikipedia - Abiogenesis
		Abiogenesis (Greek a-bio-genesis, "non biological origins") is, in its most general sense, the generation of life from non-living matter.
		As knowledge of microscopic forms of life increased, so the apparent realm of abiogenesis increased, and it became tempting to hypothesise that while abiogenesis might not take place for creatures visible to the naked eye, there existed a fount at the microscopic level from which living organisms continually arose from inorganic matter.
		One must conclude that, contrary to the established and current wisdom a scenario describing the genesis of life on earth by chance and natural causes which can be accepted on the basis of fact and not faith has not yet been written.

	Abiogenesis - CreationWiki
		Abiogenesis (Greek a-bio-genesis, "non biological origins") is a theory which contends that organisms have originated from nonliving material at some point in the distant past.
		Many evolutionists have now chosen to remain agnostic on the actual origin of life, and will frequently try to dodge the issue by claiming that abiogenesis is not part of the theory of evolution.
		The hypothesis of abiogenesis remains virtually unchanged since its inception in the 1920s, and assumes that life originated at some point in earth's past under conditions no longer present.

	Why Abiogenesis Is Impossible
		Evidence for a large number of transitional forms to bridge the stages of this process is critical to prove the abiogenesis theory, especially during the early stages of the process.
		The plausibility of abiogenesis has changed greatly in recent years due to research in molecular biology that has revealed exactly how complex life is, and how much evidence exists against the probability of spontaneous generation.
		Abiogenesis is only one area of research which illustrates that the naturalistic origin of life hypothesis has become less and less probable as molecular biology has progressed, and is now at the point that its plausibility appears outside the realm of probability.

	Abiogenesis - SkepticWiki (Site not responding. Last check: 2007-10-29)
		Abiogenesis is the process by which life originates from unliving manner, as presumably happened at some point in the past on Earth.
		Abiogenesis is separate from the question of Theory of Evolution, although many creationists do not properly make the distinction.
		Despite the theoretical separability of "evolution" and "abiogenesis," scientists are of course interested in the questions of the origins of life.

	Abiogenesis
		Aristotle explicitly taught this form of abiogenesis, and laid it down as an observed fact that some animals spring from putrid matter, that aphids arise from the dew which falls on plants, that fleas are developed from putrid matter, that mice come from dirty hay, and so forth.
		From the seventeenth century onwards it was gradually shown that, at least in the case of all the higher and readily visible organisms, spontaneous generation did not occur, but that omne vivum ex ovo, every living thing came from a pre-existing living thing.
		Although the hypothesis of panspermia is not in conflict with the idea of abiogenesis, Hoyle's interpretation of panspermia is in conflict.

	The Myth of Abiogenesis
		Below, the standard theory of abiogenesis, as presented in the nearly uniform testimony of evolutionist teaching and textbooks, will be demonstrated as scientifically untenable, based upon scientific knowledge which has actually been experimentally determined (rather than resting solely in the realm of theory).
		Abiogenesis, after amino acids and other life-necessary precursors were formed, was proposed to proceed in the primal oceans.
		Abiogenesis, in fact, violates several basic principles of chemistry and biochemistry which are so universally held as to be axiomatic.

	Why Is Abiogenesis Impossible? - ChristianAnswers.Net
		The difficulties of terrestrial abiogenesis are so great that some evolutionists have hypothesized that life could not have originated on earth but must have been transported here from another planet via star dust, meteors, comets, or spaceships (Bergman, 1993b)!
		Darwin evidently recognized how serious the abiogenesis problem was for his theory, and once even conceded that all existing terrestrial life must have descended from some primitive life form that was called into life "by the Creator" (1900, p.
		By far the greater part of the plasm that comes under investigation as active living matter in organisms is metaplasm, or secondary plasm, the originally homogeneous substance of which has acquired definite structures by phyletic differentiations in the course of millions of years (1905, p.126).

	Biogenesis & Abiogenesis - America's Debate
		The main reason why many scientists deny abiogenesis is the fact that it is negenthropic process (which is pretty obvious).
		Abiogenesis can only work if some process actually makes life, if some law exists that makes matter produce life.
		Religious people who are against the theory of abiogenesis are not truly offering an alternative - after all, "God" would have created life out of nothing - unless he too is biologically alive, in which case he came from some other life in turn.

	GMAT Reading Comprehension: Section 6: Short Passage 3 - Abiogenesis
		Aristotelian abiogenesis, also known as spontaneous generation, was the theory according to which fully formed living organisms sometimes arise from not-living matter.
		Although Aristotle may have originated the idea of Abiogenesis, he is unlikely to be the only theorist to teach the theory.
		It is likely to be found in an encyclopedia under the term "Abiogenesis." The passage's focus on a single theory makes it unlikely to appear in a history textbook (C), as a history textbook is too general to go into detail on one specific theory.

		Abiogenesis is the theory that life can arise spontaneously from non-life molecules under proper conditions.
		Darwin evidentially recognized how serious the abiogenesis problem was for his theory, and once even conceded that all existing terrestrial life must have descended from some primitive life form that was called into life “by the Creator” (1900, p.
		A major issue then, in abiogenesis is “what is the minimum number of possible parts that allows something to live?” The number of parts needed is large, but how large is difficult to determine.

	Pretending that Evolutionary Theory is Separable from Abiogenesis \| Uncommon Descent
		Therefore, the disconnecting of abiogenesis with Darwinism is a means of life-preservation — to simply cut off from discussion the more abysmal findings about the theory.
		Therefore, even though they know that evolutionary theory _should_ be separate from abiogenesis, they have too much institutional baggage to deal with the issue on a broad scale, and noting the implications it could have across the board.
		However, Haeckel tried to blur the demarcation of abiogenesis (properly speaking at that time it was known as spontaneous generation not abiogenesis) and subsequent evolution.

	Biogenesis and Abiogenesis (1870)
		The beef is dead ox, and the hay is dead grass; but the "organic molecules" of the beef or the hay are not dead, but are ready to manifest their vitality as soon as the bovine or herbaceous shrouds in which they are imprisoned are rent by the macerating action of water.
		With organic chemistry, molecular physics, and physiology yet in their infancy, and every day making prodigious strides, I think it would be the height of presumption for any man to say that the conditions under which matter assumes the properties we call "vital" may not, some day, be artificially brought together.
		If it may be generated by Abiogenesis, or by Xenogenesis, within the silkworm or its moth, the extirpation of the disease must depend upon the prevention of the occurrence of the conditions under which this generation takes place.

	Abiogenesis: The First Frontier
		Abiogenesis is basically an attempt to explain the origin of life while nullifying the possibility of a creator.
		Early Abiogenesis Experiments: Perhaps most influential to the study of Abiogenesis is the famous Stanley Miller experiment in which he ran large currents of electricity through a container of what he believed to represent the conditions of prebiotic earth.
		Abiogenesis is an attempt to explain the origin of life without considering the possiblity of direct intervention in this origin by a "creator", however it would not nullify the possibility that a "creator" existed for steps leading up to abiogenesis (such as creation of the cosmos, formation of the planets, etc).

	Biogenesis - Wikipedia, the free encyclopedia
		Primarily, they do not respond to stimuli, they are ataxic, they lack the ability or the mechanics to grow or reproduce on their own, and they do not possess cells.
		Still, proponents of the idea of abiogenesis cite these results in support of their position, stating that both "non-living" viruses and "living" bacteria are solely "molecular machines" of different complexity.
		They also say that creationists' use of the law as an argument against theories of common descent is an example of the fallacy of false dilemma, since it is imaginable that a creator god created the LUCA or one of its ancestors, from which point on evolution occurred in a guided or unguided fashion.

		Abiogenesis is the belief that life came from non-life, which would mean that before minds or any living beings came into existence there was non-life.
		I agree that at least the actual distinction given - that abiogenesis is the first origin of primitive life, passing through several prebiotic stages where it hardly could be classified as life - and spontaneous generation was the idea that more complex organisms would arise from present conditions.
		Even though he didn't believed in abiogenesis occurring nowadays, with that knowledge about origin and nature, complexity of life, one couldn't see much trouble with the primordial abiogenesis occurring this day, and that could be referred as spontaneous generation of life.

		This [my claim that abiogenesis is seperate from the Theory of Evolution] is the old definition switch Evolutionists are so fond of.
		Abiogenesis is related to evolution as the Big Bang is related to various theories in physics.
		Now abiogenesis is part of biology and if true is related to the Theory of Evolution in that it provides an explanation for what the Theory of Evolution takes as a given.
