Prior to the 17th century the idea of spontaneous generation was held as the way new organisms were produced. This idea was based on the observations of the experiment in the diagram above. The flask on the left was covered with a piece of cheesecloth. The flask on the right was left uncovered. How could the experiment have been revised so that scientists of the day could make a different inference about the mechanism for the creation of life?
