How did Pasteur's experiment help disprove spontaneous generation?
How was spontaneous generation theory then disproved.
Many people believed for centuries in spontaneous generation, which is the creation of life out of organic matter. Francesco Redi proved that spontaneous generation is not possible for large organisms. He showed that maggots can only be created from meat when flies lay eggs in it.
You might also wonder, "What was Pasteur's control?" Pasteur had both positive and negative controls in his experiments. He knew that samples in straight-necked flasks would be contaminated by microorganisms, but he also knew that the flasks would stay sterile.
People often ask: Why is spontaneous generation wrong? How did Redi's and Pasteur’s experiments disprove this idea?
In 1668, an Italian physician named Francesco Redi came up with a hypothesis to disprove the idea of spontaneous generationaspecifically, the thought that maggots could come to life from meat. He concluded that maggots form only when flies are in contact with meat, and spontaneous generation is not possible.
Did Louis Pasteur believe spontaneous generation?
The belief in spontaneous generation was held until the 1860s when Louis Pasteur's experiments introduced germ theory to the rest of the world. Pasteur wasn't the only one to question spontaneous generation. Francesco Redi, an Italian scientist, had conducted experiments 200 years before Pasteur and reached similar conclusions.
