Louis Pasteur


The idea of biogenesis was commonly believed before the experiments of Louis Pasteur. Worms appeared in dead meat, wine soured as living things "spontaneously appeared. These and other observations led to the idea that it was easy for live to occur from non living things.

Pasteur did experiments between 1855 and 1864 that proved life only came from life. Complex organisms only come from complex organisms by reproduction. This went against the idea of descent through modification proposed by Charles Darwin.

Franceso Redi in 1668 also did experiments proving that fly larva came only from flies. Maggots were thought to occur spontaneously.
Redi did controlled experiments that proved maggots did not come from dead meat spontaneously.

These experiments disproved the theory of a biogenesis that life could come from non living things.

The experiments of Louis Pasteur and Redi established the theory of biogenesis, that complex organisms come only from complex organisms.
