What was a historical experiment performed to test the theory of spontaneous generation?

Answer 1

In 1668, Italian physician Francesco Redi performed an experiment to test the prevailing theory that maggots were formed spontaneously (abiogenesis) in rotting meat.

He took 4 pieces of fresh meat and put them in containers, covering two of the containers with paper and leaving the other two uncovered. In a day or two, maggots appeared in the meat samples that were uncovered, because flies had laid their microscopic eggs in the meat. No maggots appeared on the covered pieces of meat, the ones the flies could not reach.

In 1745, however, John Needham experimented with boiling solutions to prevent spoilage in grain. Needham either did not boil his solutions long enough, or accidentally contaminated the results, because he found bacteria that had apparently appeared spontaneously. These results were challenged by the Italian Lazzaro Spallanzani in 1768, and eventually by Louis Pasteur, who proved in 1859 that bacteria existed in the open air but did not form by themselves.
