Detailed explanation-1: -Spontaneous generation theory is an archaic scientific theory which stated that living organisms could arise from nonliving matter and that such a process was regular in nature. It also explained the origin of life from the nonliving subjects.
Detailed explanation-2: -The theory of spontaneous generation states that life arose from nonliving matter. It was a long-held belief dating back to Aristotle and the ancient Greeks.
Detailed explanation-3: -Cells can only be formed by division of pre-existing cells. The first cells must have arisen from non-living material. The origin of eukaryotic cells can be explained by the endosymbiotic theory.
Detailed explanation-4: -“Spontaneous generation” was the idea that living organisms can spring into existence from non-living matter.
Detailed explanation-5: -Louis Pasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment. He subsequently proposed that “life only comes from life.”
