It is set against the idea of spontaneous generation, which is the idea that life can spontaneously form in non-living matter.Spontaneous generationSince ancient times, people have observed life such as mold and maggots appearing from seemingly nonliving matter. It was concluded that life simply could emerge spontaneously.BiogenesisBiogenesis theory began when scientists began to observe microscopic life through microscopes. With this, it became clear that the apparent spontaneous growth of life was actually from pre-existing life.TheoryBiogenesis means that living cells can arise only from pre-existing, living cells. The presence of billions of microscopic lifeforms around us is responsible for the growth of molds and other life that appears around us.Louis PasteurSpontaneous generation was refuted in an experiment run by scientist Louis Pasteur in 1859.
