Odpove\u010f na ot\u00e1zku, kde sa na na\u0161ej plan\u00e9te ukr\u00fdvaj\u00fa tie najpodivnej\u0161ie ekosyst\u00e9my, sa mo\u017eno nach\u00e1dza v prastar\u00fdch vod\u00e1ch.

Po\u010das v\u00fdskumu, ktor\u00e9ho v\u00fdsledky boli publikovan\u00e9 v \u0161t\u00fadii<\/a> z roku 2014, vedci identifikovali 19 ban\u00ed v r\u00f4znych lokalit\u00e1ch, ktor\u00e9 skr\u00fdvali vodu bohat\u00fa na vod\u00edk. T\u00e1to voda bola po mili\u00f3ny a\u017e miliardy rokov izolovan\u00e1 v prekambrickej kontinent\u00e1lnej litosf\u00e9re \u2013 teda v najstar\u0161ej a najstabilnej\u0161ej pevnej vrstve Zeme, ktor\u00e1 vznikla v obdob\u00ed prekambrium.

Jedno z t\u00fdchto miest sa nach\u00e1dza a\u017e v trojkilometrovej h\u013abke \u2013 ide o ba\u0148u ne\u010faleko kanadsk\u00e9ho mesta Timmins. Pr\u00e1ve tu vedci na\u0161li najstar\u0161iu tekut\u00fa vodu<\/a>, ak\u00e1 bola kedy objaven\u00e1, a bola izolovan\u00e1 po dobu 1,5 a\u017e 2,64 miliardy rokov.<\/p>\n

Prekambrium ozna\u010duje najstar\u0161ie obdobie dej\u00edn Zeme, od vzniku plan\u00e9ty pred 4,6 miliardami rokov a\u017e po za\u010diatok kambria pred 541 mili\u00f3nmi rokov. Ako vysvet\u013euje<\/a> geologi\u010dka Katar\u00edna Keratov\u00e1, toto obdobie tvor\u00ed pribli\u017ene 86 % celej geologickej hist\u00f3rie Zeme. \u201ePr\u00e1ve v tejto \u00e9re vznikla zemsk\u00e1 k\u00f4ra, prv\u00e9 moria a prakontinenty, zrodil sa prv\u00fd \u017eivot a v z\u00e1vere aj mnohobunkov\u00e9 organizmy s m\u00e4kk\u00fdm telom,\u201c dod\u00e1va.<\/p>\n

Najv\u00e4\u010d\u0161iu \u00falohu zohr\u00e1vaj\u00fa dva z\u00e1kladn\u00e9 chemick\u00e9 procesy. Prv\u00fdm je proces zn\u00e1my ako tzv. r\u00e1diolytick\u00fd rozklad, ktor\u00fd rozklad\u00e1 molekuly vody na vod\u00edk pod vplyvom prirodzen\u00e9ho \u017eiarenia. Druh\u00fdm je chemick\u00e1 reakcia zn\u00e1ma ako tzv. serpentiniz\u00e1cia, pri ktorej sa ur\u010dit\u00e9 miner\u00e1ly v star\u00fdch hornin\u00e1ch menia a pritom produkuj\u00fa vod\u00edk.<\/p>\n
