Spontaneous generation, the theory that life forms can be generated from inanimate objects was the commonly held belief of the time. Scientist X, took eight jars, placed meat in all the jars, but covered four of the jars with gauze. Maggots developed in the open jars but did not develop in the gauze-covered jars.
