Levende v\u00e6sener \u00e5nder, spiser, vokser og f\u00e5r afkom. De sp\u00e6nder fra de enkleste encellede bakterier til planter, fugle, dyr og mennesker. Jorden er den eneste verden, vi kender, hvor der findes liv. Ingen ved, hvordan livet opstod. Det ser ud til at have noget at g\u00f8re med, at visse kemiske stoffer er kommet sammen. Men hvad der forvandler disse kemiske stoffer til livsformer, er et mysterium.<\/p>\n<\/div>\n

Unders\u00f8gelser af gamle bjergarter har vist, at livet opstod p\u00e5 Jorden for omkring 3 800 millioner \u00e5r siden. Dengang var Jorden et meget uvenligt sted. Luften var tung og giftig. Kometer og meteoritter regnede ned over planeten.<\/p>\n

Den unge Jord var en vandverden med sm\u00e5 omr\u00e5der med t\u00f8rt land. Mange forskere mener, at livet opstod i s\u00f8erne og havene. Mange af de bestanddele, som livet opstod ud fra, kan v\u00e6re blevet bragt hertil af kometer og meteoritter.<\/p>\n

Begyndte livet i havene?<\/p>\n

Lyn og ultraviolet lys fra Solen kan have spaltet de brintrige gasser i atmosf\u00e6ren. Energien kan ogs\u00e5 stamme fra varme kilder p\u00e5 havbunden, der kaldes \u2018sorte r\u00f8gs\u00f8jler\u2019. Med tiden forenede de enkle kemiske forbindelser sig og dannede st\u00f8rre, mere komplekse kemiske forbindelser.<\/p>\n

Da disse kemikalier var samlet sig i havene eller s\u00f8erne, dannede de en \u2018organisk suppe\u2019. En dag skete der et uheld. Et molekyle begyndte at lave kopier af sig selv. Jorden var kommet til live.<\/p>","protected":false},"excerpt":{"rendered":"
