Louis+Pasteur+and+Spontaneous+Generation

Louis Pasteur discovered that spontaneous generation is not real. living things do not come from non living things for example, worms don't come from meat and frogs don't come from mud by not letting food expose to the air. the doctrine of spontaneous generation was coherently synthesized by Aristotle who compiled and expanded the work of prior natural philosophers and the various ancient explanations of the appearance of organisms; it held sway for two millennia.
