Know what the Spontaneous Generation Debate was, which scientists played a part, and how each contributed to settling the debate. Who finally disproved it? How? Why didn't the other experiments prove/disprove spontaneous generation? penned by Aristotle, held its own for over 2000 years. Francesco Redi did not believe in spontaneous generation. 1668, set up an experiment to disprove it. (Meat in the flask experiment. One uncovered, one with a film, and one with a cork.
