Ukuvela ubomi emhlabeni

Kukho izimvo ezininzi, yeengcinga neengcamango malunga ngemvelaphi yobomi emhlabeni. Okokuqala kukho ithiyori zenkolo. abameli bayo bakholelwa ukuba ubomi - kubangelwa ngolwalathiso lobuthixo. Nangona ingcamango wabonakala kumaxesha amandulo, ukuba ayenziwa kwaye namhlanje, ingakumbi kwizikolo ecaweni. Ukufundwa ubufundisi Modern ngokunxulumene eziye zafunyaniswa rhoqo ejoliswe ecacisa kufunyaniswe zizazinzulu. Ithiyori alikhange wabonakala, okanye bungangqinwa. Ububi layo ukuba nzululwazi kwaye ayikwazi siphandwe experiments.

Ukuvela ubomi emhlabeni bugwetyelwe njengoko ngobhalo panspermia. Abalandeli bakhe hypothesized imvelaphi extragalactic. Abamele - iRichter, P. various, Helmholtz kunye nabanye. Ngoko ke, Gemgolts wayekholelwa ukuba imbewu iintsholongwane kunye nezinye izinto kwaziswa Earth kunye awe esibhakabhakeni. Ngoncedo nemvavanyo zaselaborathri kwafunyaniswa ukuba izinto eziphilayo ukumelana kumaqondo obushushu asezantsi kunye nezinye iziphumo ezibi. Nkqu ixesha elide ekugugeni iimbewu zezityalo kunye imbewu nitrogen engamanzi okanye oxygen nto ikhokelele ekufeni kwabo. Kukho uluvo lokuba ubomi yenziwe njengabaphambukeli isithuba ngabom okanye ngempazamo. Kukwakho uluvo ukuba eluthulini kunye negesi amafu indawo apho iintsholongwane. Bona kuthinjwa ezinomsila kunye zakutshanje wabetha ngayo emhlabeni.

Kukho nezinye ngemvelaphi yobomi emhlabeni. Umzekelo, urhulumente umile komhlaba. abameli bayo bakholelwa ukuba ubomi khona ngonaphakade. Forms kwakhona ebesoloko ekho yaye abasayi kuvuka. Ibuya ungatshintsha kuphela ubungakanani okanye uhlobo oluthile ukufa ngokupheleleyo. Abalandeli musa ingqalelo kungenzeka abe khona iifom enguqu. Ekuxhaseni yezikhundla zabo kubakhokela iintlanzi Crossopterygii - coelacanth, ixesha elide LITHILE ifomu lenguqu ukusuka iintlanzi emanzini. Noko ke, ngo-1939, waxwilwa nekopi yokuqala intlanzi, kwandule elilandelayo. Oku kwabonisa ukuba coelacanth - akusiso yenguqu. Kwakukho nezinye imizekelo ubhaqo kwakujongwa eziphilayo extinct.

Ukuvela ubomi emhlabeni uba lilungisa, kunye kwemvelo. Abameli bakholelwa ukuba indalo kwasekwa 15 billion kwiminyaka eyadlulayo ngenxa Big Bang. Emva steel bungu isuswe ngesantya esiphezulu enye kwenye. Ngenxa yokuba umhlaba phantsi kwempembelelo reactions kwemichiza kunye zombane emoyeni kunye namanzi kwakhiwa iikhompawundi organic, ngoko ubomi baqalisa baza inkqubo yokuzivelela kwezinto eziphilayo.

Ngokutsho kwithiyori zengqo- ka Oparin, ukuvela ubomi emhlabeni ingqalelo ngenxa kwemvelo yematha. Esilula into ephilayo isuka yeegesi lokuqala esesibhakabhakeni. Ngenxa yoko kuyondelelaniswe abiogenous ze-oganikhi khompawundi akha uluhlu iiprothini kunye nucleic. Kamva inkqubo fazoobosoblennye wabumba kwezinto eziphilayo, ethe ababezahlule bume ndizayo engaphandle. Ke kwakukho imbonakalo iiseli ezilula, banayo iimpawu zazivelela ubomi kunye ezilandelayo. L.Millera Ngexesha amalinge oko kwabonisa ukuba acid kunye nezinye emvelo ukuze kwakheke iikhompawundi zondle phantsi ukukhanya yelanga kunye okuchithwa zombane.

hypothesis mihla ubomi emhlabeni yahlukile, kunjalo, hypothesis iqhubekayo ukuba ihlabathi RNA. Abalandeli bakholelwa ukuba ngexesha zazivelela yemichiza yaba eliphakathi eqongeni, xa iimolekyuli RNA ngamnye nanda akhuphisane. Ngenxa izifundo, kwafunyaniswa ukuba izakhi ezithile RNA ukuze senze ngokufanayo ngaphandle iimolekyuli protein ezintsonkothileyo.
