![]() ![]() Redi would show people that venom came from a fang, in the form of a yellow fluid. There were many misconceptions about what would happen to a person when exposed to venom. He was able to provide this type of experiment because of past work with snake venom. It is this controlled process, where ideas can be compared to one another so that findings can have evidence to support them, that has become part of the science since this initial experiment. This allowed Redi to show the maggots on top of the gauze, not in the jar with the cork, and on the meat with the open jar. The flies could not get through the cork, but they did reproduce on top of the gauze. One was covered in cork, while the other was covered in gauze. He left just one jar uncovered, while covering two others. Why? Because the maggots are a life-stage of the fly, which Redi would document when reporting his findings. As one might guess, maggots developed in the uncovered jars, but did not develop in the jars that were covered. He would then cover 3 of the jars with muslin and leave the other 4 uncovered. He took 6 jars and placed a piece of meat into all of them. ![]() The experiment by Francesco Redi was quite basic. To do this, he created a controlled experiment. What Redi wanted to do was disprove the idea that living things could be spontaneously generated from non-living cells. Therefore, if someone were to leave meat outside in the heat and allow it to spoil, the maggots that would eventually come out of the meat were a “spontaneous” occurrence. If a person couldn’t see something happen, then it was assumed that nothing happened. In the early days of science, people relied on what their senses told them. What made Redi’s work so notable was the fact that he relied on the information that controlled experiments could provide. He was a published poet, a working physician, and an academic while pursuing a passion in science. Born in Italy, his 17th century experiments were just one aspect of his life.

Redi was also a poet, his best known work being " ". Also, when dead flies or maggots were put in sealed jars with dead animals or veal, no maggots appeared, but when the same thing was done with living flies, maggots did appear. ![]() He continued his experiments by capturing the maggots and waiting for them to metamorphose, which they did, becoming common flies. After several days, he saw maggots appear on the objects in the open jars, on which flies had been able to land, but not in the gauze-covered jars. Redi took the first group of four jars, and covered the tops with fine gauze so that only air could get into it. In the experiment, Redi took eight jars, which he divided in two groups of four: in the first jar of each group, he put an unknown object in the second, a dead fish in the last, raw chunk of veal. At the time, prevailing wisdom was that maggots formed naturally from rotting meat. Francesco Redi (February 18/19, 1626– March 1, 1697) was an Italian physician.īorn in Arezzo, Tuscany, to a family of nobility, he is most well-known for his experiment in 1668 which is regarded as one of the first steps in refuting " spontaneous generation" - a theory also known as Aristotelian abiogenesis. ![]()
