Prominent scientists designed experiments and argued both in support of (John Needham) and against (Lazzaro Spallanzani) spontaneous generation. Louis Pasteur is credited with conclusively disproving the theory of spontaneous generation with his famous swan-neck flask experiment. He subsequently proposed that “life only comes from life.”

The theory of spontaneous generation was finally laid to rest in 1859 by the young French chemist, Louis Pasteur. The French Academy of Sciences sponsored a contest for the best experiment either proving or disproving spontaneous generation. Pasteur's winning experiment was a variation of the methods of Needham and Spallanzani.

In order to test Needham's theory, Spallanzani put broth in a flask, sealed the flask so that way no air could get in, and boiled it. No organisms grew in that flask. Many people said that all that Spallanzani did was prove that Spontaneous Generation did not occur when there was no air.

On the other hand, Athenaeus also dissented towards spontaneous generation, claiming that a variety of anchovy did not generate from roe, as Aristotle stated, but rather, from sea foam. As the dominant view of philosophers and thinkers continued to be in favour of spontaneous generation, some Christian theologians accepted the view.

3. Evidence used to support spontaneous generation was the observation that foods over time became covered in maggots or fungal and bacterial growth. The inference behind spontaneous generation is that there is no "parent" organism. Write this inference as a hypothesis using an if-then sentence that suggests a way of testing it.

To disprove the theory of spontaneous generation, Louis Pasteur devised a way to flask that allowed oxygen in, but prevented dust from entering. Pasteur discovered that the destruction of bacteria can be accomplished by exposing them to a specific minimum temperature for specific minimum amount of time.3/5(1)

However, Spallanzani’s experiments were inconclusive to some, because it was argued that Spallanzani’s methods deprived air from the mixture, which may have been the critical ingredient for life to come from nonliving things. Louis Pasteur eventually resolved the issue by allowing air, and only air, to come in contact with properly heated ...

Louis Pasteur finally disproved spontaneous generation through an experiment where beef broth was sterilized through boiling in two flasks, one that was exposed to air and another that was protected from it. The one that was exposed to contaminants clouded, showing microbial growth, while the sealed one did not.
