Nikt nie wie, jak ani dlaczego powsta\u0142o \u017cycie. Wiemy jednak, \u017ce \u017cycie na Ziemi pojawi\u0142o si\u0119 co najmniej 3,8 miliarda (3 800 000 000) lat temu. W tym czasie m\u0142oda planeta ostyg\u0142a i uformowa\u0142a si\u0119 jej skalista skorupa. Niekt\u00f3rzy naukowcy uwa\u017caj\u0105, \u017ce \u017cycie powsta\u0142o w skalnym basenie lub w oceanie. Inni s\u0105dz\u0105, \u017ce mog\u0142o ono przyby\u0107 z kosmosu wraz z kometami i asteroidami.<\/p>\n<\/div>\n

Z tego, co wiemy, Ziemia jest jedynym miejscem, w kt\u00f3rym wyst\u0119puje \u017cycie. Gdziekolwiek spojrzymy na naszej planecie, bakterie i inne proste formy \u017cycia znalaz\u0142y tu sw\u00f3j dom.<\/p>\n

Ro\u015bliny i zwierz\u0119ta potrzebuj\u0105 \u015bwiat\u0142a s\u0142onecznego, aby rosn\u0105\u0107. A\u017c do lat 70. XX wieku naukowcy s\u0105dzili, \u017ce \u017cycie istnieje wy\u0142\u0105cznie w pobli\u017cu powierzchni Ziemi.<\/p>\n

Od tamtej pory odkryto bakterie znajduj\u0105ce si\u0119 kilka kilometr\u00f3w pod ziemi\u0105, w litej skale. \u017byj\u0105 one dzi\u0119ki gazom i minera\u0142om zawartym w skale. Bakterie znaleziono r\u00f3wnie\u017c w silnych kwasach, w mro\u017anej Antarktyce oraz w pobli\u017cu gor\u0105cych \u017ar\u00f3de\u0142 w ciemnych g\u0142\u0119binach oceanu. Niekt\u00f3re z nich potrafi\u0105 przetrwa\u0107 nawet w miejscach o wysokim poziomie promieniowania. Dop\u00f3ki dost\u0119pna jest woda, \u017cycie jest w stanie si\u0119 zakorzeni\u0107.<\/p>\n

Je\u015bli \u017cycie jest tak trudne, czy mog\u0142oby powsta\u0107 i przetrwa\u0107 na innych \u015bwiatach? Najbardziej prawdopodobnym miejscem w naszym Uk\u0142adzie S\u0142onecznym jest Mars.<\/p>","protected":false},"excerpt":{"rendered":"
