Their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).
Explanation:
Redi put meat in three different jars one jar with covering and another without covering and the 3rd jar was sealed. He disproved spontaneous generation theory in this experiment. He showed that maggots did not come directly to meat but came from eggs laid by flies The sealed jar had no maggots in the meat.
Pasteur also checks the spontaneous generation theory by putting the boiling broth in different flasks, some open and some sealed. The conclusion he drew from this is that living things did not come from broth directly.
Thus, their experiment showed that the flies did not come directly from meat but flies laid their eggs there (disprove the spontaneous generation).
