How did Pasteur's experiment help disprove spontaneous generation?
Regarding this, how was the spontaneous generation theory disproved?
For many centuries many people believed in the concept of spontaneous generation, the creation of life from organic matter. Francesco Redi disproved spontaneous generation for large organisms by showing that maggots arose from meat only when flies laid eggs in the meat.
Likewise, what was the control in Pasteur's experiment? Pasteur's experiments contained both positive controls (samples in the straight necked flasks that he knew would become contaminated with microorganisms) and negative controls (samples in the sealed flasks that he knew would remain sterile).
One may also ask, why is the idea of spontaneous generation incorrect How did Redi and Pasteur's experiments disprove this concept?
In 1668, an Italian physician named Francesco Redi came up with a hypothesis to disprove the idea of spontaneous generation–specifically, the thought that maggots could come to life from meat. He then concluded that maggots only form when flies come in contact with meat and that spontaneous generation is not at play.
Did Louis Pasteur believe spontaneous generation?
Belief in spontaneous generation lasted until the 1860s, when Louis Pasteur's experiments brought germ theory to the world. Yet Pasteur was not the first to doubt spontaneous generation: 200 years earlier an Italian named Francesco Redi conducted his own experiments and came to similar conclusions.
