Biology Until the early nineteenth century, many scientists, philosophers and even the most educated people believed that life arose through two ways: by their peers (parents) and by spontaneous generation. "These ideas about abiogenesis were commonly accepted until about two centuries ago. Still in the thirteenth century, there was a popular belief that certain trees originated coastal geese; reported that some trees bearing fruit similar to melons, however containing sheep fully formed in its interior. In the sixteenth century, Paracelsus (Theophrastus Phillipus Aureolus Bombastus von Hohenheim (1493-1541), was a famous physician, alchemist, astrologer and physical), described several observations about the spontaneous generation of various animals, such as frogs, rats, eels and turtles, from sources such as water, air, rotten wood, straw, among others. Scientists from all fields of learning believed, for example, that the flies were originating from the raw material of garbage. Already in the seventeenth century in response to questions from Sir Thomas Browne (1605 - 1682), (English author of varied works that disclose his wide learning in diverse fields including medicine, religion, science and esoterica), about "whether mice might arise from putrefaction "Alexander Ross (1590-1654), writer, replied: So can he (Sir Thomas Browne) doubt whether cheese or wood worms originate, or if beetles and wasps feces of cows, or if butterflies, crayfish, grasshoppers, oysters, snails, eels, and so on, are procreated matter putrefied, which is able to receive the form of creature to which it is by formative power, transformed. Question it is to question reason, sense and experience. If he doubts go to Egypt, and there he will find fields full of mice, offspring of the mud of the Nile, to the great calamity of the inhabitants.

Being the spontaneous generation hypothesis that a living being born from inanimate matter, some scientists taught the recipe to produce some creatures, such as rats. It was a very simple recipe, get the sweaty underwear and put them in a jar, covering them with wheat and wait 21 days, which is the gestation period of rats. Was ready for production, and with greater success. This idea of life arising spontaneously seems absurd to us, but imagine you living at the time of spontaneous generation, and watching an animal inside the guava. Probably not if you would question how it would have appeared there and yes, believe it would have been born or produced their own guava. As can be seen, life and reproduction are interrelated.

Biologija Do ranog devetnaestog stoljeća, mnogi znanstvenici, filozofi, pa čak i najobrazovaniji ljudi vjerovali da je život nastao kroz dva načina: prema njihovim vršnjacima (roditelji) i spontane generacije. "Ove ideje o samozačeće obično su prihvaćeni do prije dva stoljeća prije još u trinaestom stoljeću, bilo je popularno vjerovanje da određene stabala nastao obalne guske, izvijestio da je neka stabla koja rode plodovima slično dinjama, međutim sadrži ovce oblikuje u svojoj unutrašnjosti. U šesnaestom stoljeću, Paracelsus (Teofrast Phillipus Aureolus Bombastus von Hohenheim (1493-1541), bio je poznati liječnik, alkemičar, astrolog i fizički), opisano je nekoliko zapažanja o spontanoj generaciji raznih životinja, kao što su žabe, štakori, jegulje i kornjače, iz izvora kao što su voda, zrak, trulo drvo, slama, među ostalima. Znanstvenici iz svih područja učenja vjeruje, na primjer, da su muhe su podrijetlom iz sirovine od smeća. Već u sedamnaestom stoljeću u odgovoru na pitanja iz Sir Thomas Browne (1605 - 1682), (engleski autor različitih djela koja otkrivaju njegovu široku učenje u različitim područjima, uključujući medicinu, religiju, znanost i ezoterije), o "bilo miševi mogli nastati iz truljenja "Alexander Ross (1590-1654), pisac, odgovorio je: Dakle, može li (Sir Thomas Browne) sumnja da sir ili drvo crve potječu, ili ako kornjaši i ose izmetu krava, ili ako leptiri, rakovi, skakavaca, kamenice, puževi, jegulje, i tako dalje, su razmnožavaju stvar trulo, koji je u stanju primiti u obliku stvorenja s kojima je od strane formativne snage, transformirala. Pitanje je to na pitanje razum, osjećaj i iskustvo. Ako on sumnja ide u Egipat, i ondje će se naći polja pune miševa, potomci blatu Nila, na veliku nesreću stanovnika.

Budući da je spontana generacija hipoteza koja živi rađa iz nežive materije, neki znanstvenici učio recept za proizvodnju nekih stvorenja, kao što štakora. To je vrlo jednostavan recept, dobiti znojni donje rublje i staviti ih u teglu, pokriva ih s pšenice i čekati 21 dana, što je gestacije štakora. Je li spreman za proizvodnju, te s većim uspjehom. Ova ideja o životu proizlazi spontano čini apsurdno da nama, ali zamislite živite u trenutku spontane generacije, i gledajući životinju unutar guave. Vjerojatno ne, ako bi ga pitao kako bi se pojavio tamo i da, vjerujem da bi bili rođeni ili stvaraju vlastite guave. Kao što se može vidjeti, život i reprodukciju međusobno su povezane.
