cork through a microscope-coins the term “cell.”
1668 Francesco Redi performs the first documented
controlled scientific experiment. Covers meat with
cheese cloth, and leaves other pieces of meet
uncovered. Uncovered meat, exposed to flies,
develops maggots. Covered meat does not develop
maggots. Redi concludes that adult flies are
necessary for the production of maggots. This is the
first major blow to the theory of spontaneous
generation.

had been disproved.
