Spontaneous generation, a theory that maggots, fleas, worms and other living organisms developed from inorganic or dead organic matter, was the prevalent viewpoint of scientists for around 2,000 years, since Aristotle first posited a description of the phenomenon. 9 What did Redi discover about spontaneous generation? What did Redis experiment with flies prove? A strong opponent of spontaneous generation, the Italian physician Francesco Redi set out in 1668 to demonstrate that maggots did not arise spontaneously from decaying meat.
