Levende vesener puster, spiser, vokser og f\u00e5r avkom. De spenner fra de enkleste encellede bakteriene til planter, fugler, dyr og mennesker. Jorden er den eneste verdenen vi kjenner til som kan opprettholde liv. Ingen vet hvordan livet oppsto. Det ser ut til \u00e5 ha sammenheng med at visse kjemiske stoffer kom sammen. Men hva som forvandler disse stoffene til livsformer, er et mysterium.<\/p>\n<\/div>\n

Unders\u00f8kelser av gamle bergarter har vist at livet oppsto p\u00e5 Jorden for rundt 3 800 millioner \u00e5r siden. P\u00e5 den tiden var Jorden et sv\u00e6rt ugjestmildt sted. Luften var tung og giftig. Kometer og meteoritter regnet ned over planeten.<\/p>\n

Den unge jorden var en vannverden med sm\u00e5 omr\u00e5der med t\u00f8rt land. Mange forskere mener at livet oppsto i innsj\u00f8er og hav. Mange av de bestanddelene som dannet grunnlaget for livet, kan ha blitt brakt hit av kometer og meteoritter.<\/p>\n

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

Lyn og ultrafiolett lys fra Solen kan ha spaltet de hydrogenrike gassene i atmosf\u00e6ren. Energien kan ogs\u00e5 ha kommet fra varme kilder p\u00e5 havbunnen, kjent som \u2018svarte r\u00f8ykere\u2019. Over tid har de enkle kjemikaliene bundet seg sammen og dannet st\u00f8rre, mer komplekse kjemikalier.<\/p>\n

Da disse kjemikaliene hadde samlet seg i havene eller innsj\u00f8ene, dannet de en \u2018organisk suppe\u2019. En dag skjedde det en ulykke. Et molekyl begynte \u00e5 lage kopier av seg selv. Livet hadde oppst\u00e5tt p\u00e5 jorden.<\/p>","protected":false},"excerpt":{"rendered":"
