It states that organisms came from non-living things.
Who was able to disprove that maggots could be spontaneously generated from meat using a controlled experiment. Also, disproved the Theory of Spontaneous Generation.
Francesco Redi
He believed that life can arise spontaneously. He repeated Redi’s experiment but yielded different result because he was not successful in killing all microbes while boiling broth.
John Needham
He disagreed to the theory of spontaneous generation after observing absence of small organisms in some chicken broth placed in sealed flasks heated for 30 minutes.
Lazzaro Spallanzani
He 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.
