Question

John Needham hypothesized that life is created by the action of oxygen on a nutrient solution. This was the basis of his experiments where he boiled nutrient solutions to kill any existing living organisms, sealed them, and then observed the growth of microorganisms that appeared in the solutions. However, later experiments by Louis Pasteur disproved this hypothesis by demonstrating that microorganisms did not spontaneously arise in sealed nutrient solutions, but rather were introduced from external sources.
