Francesco Redi
He had two jars with a steak in it. In the first jar he left it open and saw that as the flies came, maggots were produced. In the next jar he put a lid and the flies weren't able to get in and no maggots were produced. Which supports how spontaneous generation isn't possible.
bacteria/ maggots etc are produced by the item which is rotting, rather than causing the rot to occur
Spontaneous generation- which is an idea or theory that someone had which is compleatly and compentanly obserd
Spontaneous Generation is a now discredited theory that certain living things could be produced spontaneously from non-living matter. For example, before the life cycle of the fly was understood, maggots were thought to be the products of Spontaneous Generation, as they seemed to appear spontaneously in dead animals at that were left exposed for a time.
Francesco Redi did an experiment in 1668 that disproved a belief that maggots spontaneously generated on rotting meat. His experiment was to place meat into sets of jars: one set he left open to the air, one set he covered with very fine gauze, one set was completely sealed. Maggots appeared on the meat in the open jars; flies laid eggs on the gauze but no maggots appeared because the scent of rotting meat provides no nourishment; nothing appeared on the meat in the completely sealed jars. Redi believed in spontaneous generation of many things, just not fly maggots. He is credited with beginning the experiments using controls method used now.
Spallanzani discovered that the theory of spontaneous generation was incorrect; boiling water is a better sterilizer than hot air; and some microorganisms can live for days in a vacuum before dying...
He demonstrated that new bacteria appeared in broth only when they were produced by living bacteria. The experiments of Redi and Pasteur helped to convince people that living things do not arise from nonliving material.
