K\u00ebrkimi p\u00ebr t\u00eb kuptuar pse ka jet\u00eb n\u00eb Tok\u00eb, duhet t\u00eb filloj\u00eb me ujin, sepse uji \u00ebsht\u00eb e vetmja gj\u00eb n\u00eb Tok\u00eb p\u00ebr t\u00eb cil\u00ebn ka nevoj\u00eb jeta.

Megjithat\u00eb shkenc\u00ebtar\u00ebt nuk e kuptojn\u00eb plot\u00ebsisht se si uji mbuloi 2\/3 e sip\u00ebrfaqes s\u00eb bot\u00ebs son\u00eb dhe krijoi kushtin e par\u00eb t\u00eb nevojsh\u00ebm p\u00ebr jet\u00ebn.

P\u00ebr dekada t\u00eb t\u00ebra, ata jan\u00eb p\u00ebrpjekur t\u00eb rikrijojn\u00eb n\u00eb laborator\u00eb kushtet e asaj Toke t\u00eb hershme t\u00eb mbushur me uj\u00eb.<\/p>\n

Mendimi mbizot\u00ebrues n\u00eb mesin e tyre, \u00ebsht\u00eb se n\u00ebse do t\u00eb munden t\u00eb imitojn\u00eb kushtet e Tok\u00ebs s\u00eb hershme, do t\u00eb jen\u00eb p\u00ebrfundimisht n\u00eb gjendje t\u00eb krijojn\u00eb di\u00e7ka t\u00eb ngjashme me qelizat e para t\u00eb thjeshta q\u00eb u formuan k\u00ebtu miliarda vjet m\u00eb par\u00eb. Nga atje, ata mund t\u00eb bashkojn\u00eb cop\u00ebzat e nj\u00eb historie se si filloi jeta n\u00eb Tok\u00eb.<\/p>\n

Kjo linj\u00eb k\u00ebrkimesh ka treguar disa suksese mbres\u00ebl\u00ebn\u00ebse. N\u00eb vitet 1950, shkenc\u00ebtar\u00ebt Harold Jurej dhe Stenli Miler, treguan se \u00ebsht\u00eb e mundur t\u00eb sintetizohet aminoacidi i glicin\u00ebs \u2013 pra nj\u00eb nga blloqet nd\u00ebrtuese m\u00eb themelore t\u00eb jet\u00ebs \u2013 duke p\u00ebrzier s\u00eb bashku disa gazra q\u00eb besohet se kan\u00eb mbushur atmosfer\u00ebn miliarda vjet m\u00eb par\u00eb, me nxeht\u00ebsi dhe me shkarkesa rrufesh t\u00eb simuluara n\u00eb laborator.<\/p>\n

Dhe ata kan\u00eb formuar molekula t\u00eb ARN-s\u00eb, t\u00eb cilat jan\u00eb si ADN-ja n\u00eb nj\u00eb form\u00eb t\u00eb thjesht\u00ebzuar. Por krijimi i t\u00eb gjith\u00eb k\u00ebtyre komponent\u00ebve t\u00eb jet\u00ebs nuk ndodhi n\u00eb nj\u00eb laborator dhe grumbullimi n\u00eb nj\u00eb qeliz\u00eb t\u00eb thjesht\u00eb.<\/p>\n

N\u00eb k\u00ebt\u00eb rast ata mund t\u00eb zbulojn\u00eb jo vet\u00ebm historin\u00eb e origjin\u00ebs s\u00eb jet\u00ebs n\u00eb Tok\u00eb, por t\u00eb arrijn\u00eb n\u00eb nj\u00eb p\u00ebrfundim trondit\u00ebs se sa e zakonshme duhet t\u00eb jet\u00eb jeta n\u00eb Univers.<\/p>\n

Pavar\u00ebsisht se nuk jemi t\u00eb sigurt se si nisi fillimisht, sot e dim\u00eb se Toka \u00ebsht\u00eb plot me forma jete. Ne e njohim jet\u00ebn kur e shohim. Por a e dim\u00eb se \u00e7far\u00eb \u00ebsht\u00eb ajo n\u00eb thelb? \u201cAskush nuk ka qen\u00eb n\u00eb gjendje ta p\u00ebrcaktoj\u00eb tamam jet\u00ebn, dhe disa njer\u00ebz do t\u2019ju thon\u00eb se kjo gj\u00eb nuk \u00ebsht\u00eb e mundur\u201d- thot\u00eb Karl Zimer, gazetar i \u00e7\u00ebshtjeve shkencore dhe autor i librit \u201cN\u00eb skajet e jet\u00ebs: N\u00eb k\u00ebrkim t\u00eb dometh\u00ebnies s\u00eb t\u00eb qenit gjall\u00eb\u201d.<\/p>\n

Dhe kjo jo p\u00ebr shkak t\u00eb munges\u00ebs s\u00eb p\u00ebrpjekjeve. \u201cEkzistojn\u00eb qindra p\u00ebrkufizime t\u00eb jet\u00ebs q\u00eb jan\u00eb publikuar nga vet\u00eb shkenc\u00ebtar\u00ebt n\u00eb literatur\u00ebn shkencore. Pyetja se \u00e7far\u00eb \u00ebsht\u00eb jeta, duket si e leht\u00eb, si di\u00e7ka q\u00eb duhet t\u2019i jap\u00eb p\u00ebrgjigje edhe nj\u00eb nx\u00ebn\u00ebs i klas\u00ebs s\u00eb pest\u00eb.<\/p>\n

Ajo ndihet sikur duhet t\u00eb jet\u00eb e leht\u00eb sepse ne e ndiejm\u00eb at\u00eb. Vet\u00eb truri yn\u00eb \u00ebsht\u00eb i p\u00ebrshtatur p\u00ebr t\u00eb njohur gj\u00ebra t\u00eb tilla si l\u00ebvizja biologjike. Ne jemi disi t\u00eb prirur p\u00ebr ta njohur jet\u00ebn.

Nga nj\u00ebra an\u00eb, nj\u00eb p\u00ebrkufizim i jet\u00ebs do t\u00eb na hynte n\u00eb pun\u00eb, nd\u00ebrsa ne jemi duke k\u00ebrkuar p\u00ebr shenja t\u00eb saj n\u00eb planet\u00eb dhe H\u00ebna t\u00eb tjera.
