Who were the scientist who challenged the idea of 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.”
Who disproved the theory of spontaneous generation using flies and rotten meat?
Redi
Redi went on to demonstrate that dead maggots or flies would not generate new flies when placed on rotting meat in a sealed jar, whereas live maggots or flies would. This disproved both the existence of some essential component in once-living organisms, and the necessity of fresh air to generate life.
How did Francesco Redi disprove the theory of spontaneous generation?
In 1668, Francesco Redi, an Italian scientist, designed a scientific experiment to test the spontaneous creation of maggots by placing fresh meat in each of two different jars. Redi successfully demonstrated that the maggots came from fly eggs and thereby helped to disprove spontaneous generation.
How does the evidence derived from this experiment refute the idea of spontaneous generation?
the evidence derived from this experiment refutes the idea of spontaneous generation because in order to have generation there must be contamination were spontaneous generation just comes out of no where and that is not possible.
Why was the theory of biogenesis challenged?
Showed the importance of oxygen to life. His theory was challenged because critics said there was not enough oxygen in the flasks to support microbial life. In 1858, this German scientist challenged spontaneous generation with the concept of biogenesis, the claim that living cells can only arise from preexisting living cells.
Who is credited with disproving the theory of spontaneous generation?

Who was the first scientist to believe in biogenesis?
Rudolf Virchow: Proponent of Biogenesis. In 1858, scientist Rudolf Virchow challenged the spontaneous generation with his concept of biogenesis. He claimed “that living cells can arise only from preexisting living cells”.
How did Pasteur disprove the theory of biogenesis?
The microorganisms are trapped in the flask’s S-shaped neck. Pasteur’s ingenious experiments changed how the world understand the origin of a living thing. He successfully disproved the idea that mystical forces in nature have the ability to generate living things from non living things spontaneously.
