Explanation: Francesco Redi was a scientist who designed an experiment to test the spontaneous creation of maggots. It consisted of placing fresh meat in two different jars; one of them was left open (so flies could enter) while the other was covered with a cloth.

As Redi predicted, maggots only appeared in the meat that came in contact with the flies, not in the covered jar. So, the experiment showed that maggots do not spontaneously arise from decaying meat but come from flies that land on it.
