To prove the impossibility of spontaneous generation, the Italian naturalist F. Redi was to
- isolate meat from indoor flies
- consider pieces of meat under a microscope
- constantly remove the larvae from the meat
- keep meat warm
In the seventeenth century, Francesco Radi (an Italian natural philosopher, physician and just an intelligent man) conducted the following experiment.
He took a few pots of meat and put them on the table in the room.
Half of the pots he covered with a cloth, half - stood open.
In those that were open to the access of flies, there were larvae - maggots.
In those that were covered with a cloth, worms could not be found.
The conclusion of F.Redi: spontaneous generation can not be spontaneous.
