Francesco Redi refuted the “spontaneous generation” theory, both location and climatology agents which a corpse is exposed to determine the composition and abundce of insect’s populations, expanded and systemized forensic entomology, stablishing the age and development rate of larvae, The place of the death strongly determines the species of arthropods we can find in a dead body as well as the succession patterns of their communities, difficulty and complexity to determine the PMI and the place of death at marine habitats, Symbiosis: relationships between living beings, Is essential to know the development degree of larvae and pupae of each species, as well as their length of their life cycles and their specific traits to estimate the PMI, (Dermestidae) and lepidopterans (e.g. He was the first scientist to challenge the theories of spontaneous generation by demonstrating … 1-5 Interesting Facts About Maggots 1.
