Frances Redi disproved spontaneous generation by designing a controlled experiment where he placed raw meat in six (6) jars. He covered three jars with a fine net and left three jars open. After a short period, maggots appeared in the open jars while the covered jars had no maggots. In your opinion, what additional controls and measurements could Frances Redi have done to prove that rotting of raw meat is caused by live bacteria?
