Aristotle proposed that life arose from nonliving material if the material contained pneuma ("vital heat"). Having observed the development of maggots and flies on decaying meat, Redi in 1668 devised a number of experiments, all pointing to the same conclusion: if flies are excluded from rotten meat, maggots do not develop. There was some confusion in one place. An additional fifth criterion was introduced subsequently which states that antibodies to the causative organism should be demonstrable in the patients serum. It also explained the origin of life from the nonliving subjects. Francesco Redi's main contribution to biology was proving that maggots did not erupt spontaneously from rotting meat, but were deposited there in the eggs of flies.

L., & Burton, G. R. W. (2011). The relative simplicity of the microorganism, their short life span and the genetic homogeneity provided an authentic simulated model to understand the physiological, biochemical and genetical intricacies of the living organisms. However, he did make a major contribution to microbiology in 1668 by . Experimental science was in its infancy, and Redi came up with a brilliant new idea: the controlled experiment.

The Johns Hopkins University Press, 1974, Raffaele Roncalli Amici A founding father of both pathology and social medicine, Virchow analyzed the effects of disease in various organs and tissues of the human body. The ideas of all three scientists Schwann, Schleiden, and Virchow led to cell theory, which is one of the fundamental theories unifying all of biology. Italian physician Francesco Redi performed an experiment in 1668 that proved that maggots DO NOT spontaneously generate on rotting meat. Francesco Redi, an Italian scientist was the first scientist to challenge the theory of spontaneous generation by demonstrating that living organisms did not actually originate from non-living things. In Redis era, people commonly believed all sorts of nonsense about snakes, such as: snakes enjoy drinking wine; its deadly to eat the flesh of an animal killed by snake venom; snakes produce venom in their gallbladders; and eating a snakes head is an antidote to its venom.

His scientific work resulted in a number of significant milestones: he showed that flies breed and lay eggs and do not, as was popularly believed, spontaneously generate; his microscopic examination of parasites marked the founding of modern parasitology; and in studying chemical treatments to kill parasites, he devised and performed the first controlled experiments in scientific history.
