Explain the theory of spontaneous generation and why people once accepted it as an explanation for the existence of certain types of organisms. Explain how certain individuals (van Helmont, Redi, Needham, Spallanzani, and Pasteur) tried to prove or disprove spontaneous generation.
Francesco Redi (born Feb. 18, 1626, Arezzo, Italy—died March 1, 1697, Pisa) was an Italian physician and poet who demonstrated that the presence of maggots in putrefying meat does not result from spontaneous generation but from eggs laid on the meat by flies.
May 30, 2017 · Francesco Redi was an Italian physician and the first scientist to suspect that the theory of spontaneous generation may be flawed, so he set up a simple experiment. He placed fresh meat into two different jars, one with a muslin cloth over the top, and the other left open.
Experimentation by Francesco Redi in the 17th century presented the first significant evidence refuting spontaneous generation by showing that flies must have access to meat for maggots to develop on the meat.

A rationalist of his time, he was a critic of verifiable myths, such as spontaneous generation. [8] His most famous experiments are described in his magnum opus Esperienze intorno alla generazione degl'insetti ( Experiments on the Generation of Insects ), published in 1668.
Sep 9, 2018 · One of Redi's most famous experiments investigated spontaneous generation. At the time, scientists believed in the Aristotelian idea of abiogenesis, in which living organisms arose from non-living matter. People believed rotting meat spontaneously produced maggots over time.

Mar 1, 2014 · Francesco Redi’s seventeenth-century experiments on insect generation are regarded as a key contribution to the downfall of belief in spontaneous generation. Scholars praise Redi for his experiments demonstrating that meat does not generate insects, but condemn him for his claim elsewhere that trees can generate wasps and gallflies.
