Editing Francesco Redi (section)

===Parasitology===
Redi was the first to describe [[ectoparasites]] in his ''Esperienze intorno alla generazione degl'insetti''. His notable illustrations in the book are those relevant to [[ticks]], including deer ticks and tiger ticks; it also contains the first depiction of the larva of [[Cephenemyiinae]], the nasal flies of deer, as well as the sheep liver fluke (''[[Fasciola hepatica]]''). His next [[treatise]] in 1684 titled ''Osservazioni intorno agli animali viventi che si trovano negli animali viventi'' (''Observations on Living Animals, that are in Living Animals'') recorded the descriptions and the illustrations of more than 100 parasites. In it, he also differentiates the [[earthworm]] (generally regarded as a [[helminth]]) and ''[[Ascaris lumbricoides]]'', the human roundworm. An important innovation from the book is his experiments in [[pharmacology|chemotherapy]] in which he employed the "[[scientific control|control]]"', the basis of [[experimental design]] in modern biological research.<ref name= lei/><ref name= ami/><ref>{{cite journal |vauthors=Ioli A, Petithory JC, Théodoridès J |title= Francesco Redi and the birth of experimental parasitology| journal= Hist Sci Med |year=1997| volume=31 |issue=1 |pages= 61–66 |pmid= 11625103}}</ref> He described some 180 species of parasites. Perhaps, his most significant observation was that parasites produce eggs and develop from them, which contradicted the prevailing opinion that they are produced spontaneously.<ref>{{cite book |vauthors=Bush AO, Fernández JC, Esch GW, Seed JR |title=Parasitism: The Diversity and Ecology of Animal Parasites |url=https://archive.org/details/parasitismdivers0000unse|url-access=registration |year= 2001 |publisher=Cambridge University Press |location= Cambridge, UK| page= [https://archive.org/details/parasitismdivers0000unse/page/4 4]| isbn=0521664470}}</ref>
