Elusolendid hingavad, toituvad, kasvavad ja j\u00e4tavad j\u00e4reltulijaid. Nende hulka kuuluvad nii k\u00f5ige lihtsamad \u00fcherakulised bakterid kui ka taimed, linnud, loomad ja inimesed. Maa on ainus meile teadaolev maailm, kus elu on v\u00f5imalik. Keegi ei tea, kuidas elu algas. Tundub, et sellega on seotud teatud kemikaalide kokkupuutumine. Kuid see, mis muudab need kemikaalid eluvormideks, on m\u00f5istatus.<\/p>\n<\/div>\n

Iidsete kivimite uuringud on n\u00e4idanud, et elu tekkis Maal umbes 3 800 miljonit aastat tagasi. Tol ajal oli Maa v\u00e4ga eluks sobimatu paik. \u00d5hk oli tihe ja m\u00fcrgine. Komeedid ja meteoriidid sadasid planeedile.<\/p>\n

Noor Maa oli veemaailm, kus oli vaid v\u00e4he kuiva maad. Paljud teadlased arvavad, et elu sai alguse j\u00e4rvedes ja ookeanides. Paljud elu tekkimiseks vajalikud koostisosad v\u00f5isid olla toodud komeetide ja meteoriitidega.<\/p>\n

Kas elu sai alguse ookeanides?<\/p>\n

P\u00e4ikesest p\u00e4rinev v\u00e4lk ja ultraviolettkiirgus v\u00f5isid l\u00f5hustada atmosf\u00e4\u00e4ris leiduvaid vesinikurikkaid gaase. Energia v\u00f5is p\u00e4rineda ka merep\u00f5hjas asuvatest kuumaveeallikatest, mida nimetatakse \u2018mustadeks suitsutajateks\u2019. Aja jooksul \u00fchinesid lihtsad keemilised \u00fchendid, moodustades suuremaid ja keerulisemaid keemilisi \u00fchendeid.<\/p>\n

Kui need kemikaalid olid kogunenud ookeanidesse v\u00f5i j\u00e4rvedesse, moodustasid nad \u2018orgaanilise supikese\u2019. \u00dchel p\u00e4eval juhtus \u00f5nnetus. \u00dcks molekul hakkas endast koopiaid tegema. Maa oli ellu \u00e4rganud.<\/p>","protected":false},"excerpt":{"rendered":"
