Badania skamienia\u0142o\u015bci w pradawnych ska\u0142ach wskazuj\u0105, \u017ce \u017cycie prawdopodobnie powsta\u0142o oko\u0142o 4 miliard\u00f3w lat temu, kiedy Ziemia by\u0142a jeszcze bardzo m\u0142oda. Nikt nie wie, jak powsta\u0142o \u017cycie na Ziemi. Wi\u0119kszo\u015b\u0107 naukowc\u00f3w uwa\u017ca, \u017ce powsta\u0142o ono w wodzie w stanie ciek\u0142ym. Ale czy mia\u0142o to miejsce w ka\u0142u\u017cach na powierzchni, pod ziemi\u0105, czy te\u017c na dnie ocean\u00f3w, gdzie aktywno\u015b\u0107 wulkaniczna tworzy gor\u0105ce \u017ar\u00f3d\u0142a?<\/p>\n<\/div>\n

Eksperymenty pokazuj\u0105, \u017ce chemiczne budulce \u017cycia mog\u0105 powstawa\u0107 zar\u00f3wno w przestrzeni kosmicznej, jak i na Ziemi. Wiele z nich musia\u0142o dotrze\u0107 na Ziemi\u0119 wraz z spadaj\u0105cymi meteorytami i kometami. W jaki\u015b spos\u00f3b te proste \u2018organiczne\u2019 zwi\u0105zki chemiczne po\u0142\u0105czy\u0142y si\u0119, tworz\u0105c bardziej z\u0142o\u017cone cz\u0105steczki. Nast\u0119pnie zacz\u0119\u0142y si\u0119 one rozmna\u017ca\u0107 i rozwija\u0107.<\/p>\n

Wiemy natomiast, \u017ce \u2013 gdy ju\u017c si\u0119 rozpocznie \u2013 \u017cycie staje si\u0119 niezwykle trudne. \u017bywe bakterie znaleziono w zamarzni\u0119tej Antarktydzie, we wrz\u0105cej wodzie oraz wewn\u0105trz ska\u0142 na g\u0142\u0119boko\u015bci si\u0119gaj\u0105cej nawet pi\u0119ciu kilometr\u00f3w pod ziemi\u0105. Wiemy r\u00f3wnie\u017c, \u017ce takie organizmy mog\u0105 przetrwa\u0107 przez lata w surowych warunkach panuj\u0105cych w przestrzeni kosmicznej.<\/p>\n

Gdy ro\u015bliny sta\u0142y si\u0119 powszechne, do atmosfery przedosta\u0142y si\u0119 ogromne ilo\u015bci tlenu. Ziemia sta\u0142a si\u0119 jedyn\u0105 planet\u0105 w naszym Uk\u0142adzie S\u0142onecznym, kt\u00f3rej atmosfera jest bogata w tlen. Poszukuj\u0105c tlenu na innych \u015bwiatach, by\u0107 mo\u017ce pewnego dnia znajdziemy dowody na istnienie obcych form \u017cycia.<\/p>","protected":false},"excerpt":{"rendered":"
