What was Redi's hypotheses?

Francesco Redi's hypotheses centered around the concept of spontaneous generation—the idea that living organisms could arise from non-living matter. He proposed that maggots on decaying meat came from eggs laid by flies, rather than spontaneously generating from the meat itself. To test this, he conducted experiments using jars with meat, some open to the air and others covered, demonstrating that maggots only appeared in the open jars. His findings challenged the prevailing notion of spontaneous generation and laid the groundwork for modern Biology.
