Abiogenesis is the theory that life evolved from non-living things or inanimate matter. It was believed that life could spontaneously generate, which was disproved by Louis Pasteur. He accomplished this by showing that the air had microorganisms floating around in it. He did this by passing air through gun cotton filters, which trapped the particles in the air. He dissolved the cotton with a mixture of ether and alcohol, which allowed the particles to settle at the bottom of the liquid. He examined the material and found numerous microbes that he knew to be present in putrefying material. He realized that if this material in the air landed on other material, it could contaminate it. He entered a contest to perform an experiment to disprove the spontaneous generation theory based off of this new knowledge. He poured a liquid medium into a flask and then killed the microbes with heat. He heated the end of the ...
