Final answer:
Francesco Redi's experiment demonstrated that maggots come from eggs laid by flies on the meat, debunking the idea of spontaneous generation.
Step-by-step explanation:
Francesco Redi's experiment in 1668 supports the hypothesis that maggots do not arise from spontaneous generation, but rather from flies laying eggs on the meat. Redi's experiment involved placing rotting meat in jars, some of which were open, some covered with gauze, and others tightly sealed. His observations showed that maggots developed only in the uncovered containers where flies had direct contact with the meat, thereby disproving the notion that maggots could spontaneously generate from the meat itself.
