Nimeni nu \u0219tie cum sau de ce a ap\u0103rut via\u021ba. \u0218tim \u00eens\u0103 c\u0103 via\u021ba pe P\u0103m\u00e2nt a ap\u0103rut cu cel pu\u021bin 3,8 miliarde (3 800 000 000) de ani \u00een urm\u0103. La acea vreme, t\u00e2n\u0103ra planet\u0103 se r\u0103cise \u0219i formase o crust\u0103 st\u00e2ncoas\u0103. Unii oameni de \u0219tiin\u021b\u0103 cred c\u0103 via\u021ba a ap\u0103rut \u00eentr-un bazin st\u00e2ncos sau \u00een ocean. Al\u021bii consider\u0103 c\u0103 ar fi putut ajunge din spa\u021biu, odat\u0103 cu cometele \u0219i asteroizii.<\/p>\n<\/div>\n

Din c\u00e2te \u0219tim, P\u0103m\u00e2ntul este singurul loc \u00een care exist\u0103 via\u021b\u0103. Oriunde ne-am uita pe planeta noastr\u0103, bacteriile \u0219i alte forme de via\u021b\u0103 simple \u0219i-au g\u0103sit un c\u0103min.<\/p>\n

Plantele \u0219i animalele au nevoie de lumina soarelui pentru a cre\u0219te. P\u00e2n\u0103 \u00een anii 1970, oamenii de \u0219tiin\u021b\u0103 credeau c\u0103 via\u021ba exista doar \u00een apropierea suprafe\u021bei P\u0103m\u00e2ntului.<\/p>\n

De atunci, au fost descoperite bacterii la c\u00e2\u021biva kilometri sub p\u0103m\u00e2nt, \u00een interiorul rocilor solide. Acestea se hr\u0103nesc cu gazele \u0219i mineralele din roc\u0103. De asemenea, au fost g\u0103site bacterii \u00een acizi puternici, \u00een frigul glacial al Antarcticii \u0219i \u00een apropierea izvoarelor termale din ad\u00e2ncurile \u00eentunecate ale oceanului. Unele pot supravie\u021bui chiar \u0219i \u00een locuri cu un nivel ridicat de radioactivitate. At\u00e2ta timp c\u00e2t exist\u0103 ap\u0103, via\u021ba reu\u0219e\u0219te s\u0103 prind\u0103 r\u0103d\u0103cini.<\/p>\n

Dac\u0103 via\u021ba este at\u00e2t de dificil\u0103, ar putea s\u0103 ia na\u0219tere \u0219i s\u0103 supravie\u021buiasc\u0103 pe alte planete? Cel mai probabil loc din Sistemul nostru Solar este Marte.<\/p>","protected":false},"excerpt":{"rendered":"
