What is the meaning of F. Redi’s experiments?

At the beginning of the XVII century. it was widely believed that the larvae of flies spontaneously originate from rotten meat. Francesco Redi (1626-1698) in his experiments decided to refute this error. He put the meat in the vessels and covered some of them with gauze. Larvae did not appear in the vessels covered with gauze where flies could not get, and in the open several days later many larvae were found. The experiments of F. Redi dealt a serious blow to the theory of spontaneous generation and confirmed the concept of biogenesis, according to which life can arise only from existing life.
