Spontaneous Generations Forms of life could arise spontaneously from non-living matter (snakes could be born of moist soil.)

The Journey from Spontaneous Generation to Biogenesis Redi‚ Leeuwenhoek‚ Needham‚ Spallanzani‚ and Pasteur changed the way we think about life by trying to prove and disprove Spontaneous Generation or the idea that life could arise from nonliving matter. Redi disproved Spontaneous Generation. He only believed in Biogenesis which is that all life comes from life. Needham believed in Spontaneous Generation and wanted to prove it. Spallanzani wanted to know what caused microbes. Pasteur put an end

Forensic entomology is using insect biology to determine specific aspects of a crime. It can be used to determine time of death‚ whether or not a body has been moved‚ and also if the victim had been intoxicated with any substances. Insects are also prime examples of Locard’s principle when solving a crime. The history of forensic entomology dates back to as early as the thirteenth century‚ and is still been developed today. There have been many cases involving forensic entomology to help solve
