40. The Spontaneous Generation Of Life Wald, George. 1954. The origin of life. Scientific American 19146. Wilson, John H. 1983. The origin of life. in Wilson, D.B., Did the devil make Darwin do it? http://www.genesispark.com/genpark/spongen/spongen.htm

THE SPONTANEOUS GENERATION HYPOTHESIS Abstract: As our knowledge of life’s microscopic secrets continues to advance it is instructive to reflect upon the history of the spontaneous generation hypothesis to contemplate whether scientific advancements are indeed progressing as the anti-creationist predicted nearly two decades ago: "If I have made my point, the next time you hear creationists talking about the ‘impossibility’ of making a particular protein, ...you can smile wryly and know that they are nowhere near a consideration of the real issues. ...Given the rapid rate of progress in our understanding of molecular biology, I have no doubt that satisfactory explanations of the problem posed here soon will be forthcoming." (Doolittle, 1983, p. 96). Aristotle (384-322BC), Greek philosopher and scientist, expressed the hypothesis that decaying material could be transformed by the ‘spontaneous action of Nature’ into living animals. Classical scientists as recently as two hundred years ago believed in vitalism, the idea that non-living material like dirt, damp hay, or decaying meat had innate vitality such that "simple" life would spontaneously arise from it. Francisco Redi is best remembered for his 18th century experiments demonstrating that maggots did not come from the meat but from the flies that had laid their eggs upon it. In the 1860’s Louis Pasteur conducted his famous scientific disproof of spontaneous generation in which he sterilized and sealed jars of nutrients, demonstrating that only life begets lifethe law of biogenesis. In reflecting upon this, Wald (himself a proponent of spontaneous generation) notes:
