Experimental science was in its infancy, and Redi came up with a brilliant new idea: the controlled experiment. 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 Fracastorius of Verona (1546) proposed a Contagium vivum as a possible cause of infections disease and Von Plenciz (1762) suggested that each disease was caused by a separate agent.

Redi explained that flies land on exposed meat and lay their eggs which eventually hatch to produce maggots.
