Ukazuje se, \u017ee kolize s nebesk\u00fdmi t\u011blesy m\u016f\u017ee v\u00e9st nejen ke zni\u010den\u00ed \u017eivota, ale tak\u00e9 k jeho rozkv\u011btu.<\/strong><\/p>\n

V\u011bdci se domn\u00edvaj\u00ed, \u017ee zlomem v rozvoji lidstva mohl b\u00fdt asteroid, kter\u00fd narazil do Severn\u00ed Ameriky, nedaleko od Quebeku, na jihu kanadsk\u00e9 provincie stejn\u00e9ho jm\u00e9na, a to p\u0159ed 12.900 roky.<\/p>\n

Kolize zp\u016fsobila n\u00e1stup chladn\u011bj\u0161\u00edho a su\u0161\u0161\u00edho klimatu na planet\u011b, co\u017e vedlo ke vzniku zem\u011bd\u011blstv\u00ed.<\/p>\n

V severn\u00ed Americe zmizela velk\u00e1 zv\u00ed\u0159ata, v\u010detn\u011b mastodont\u016f, velbloud\u016f, ob\u0159\u00edch lenochod\u016f a \u0161avlozub\u00fdch tygr\u016f.<\/p>\n

To p\u0159inutilo Ameri\u010dany, kte\u0159\u00ed byli lovci, p\u0159ej\u00edt na dietu, skl\u00e1daj\u00edc\u00ed se z ko\u0159en\u016f, plod\u016f a drobn\u00e9 zv\u011b\u0159e.<\/p>\n

Tis\u00edce kilometr\u016f daleko od Ameriky, ve v\u00fdchodn\u00edm St\u0159edomo\u0159\u00ed, prvn\u00ed zem\u011bd\u011blci sou\u010dasn\u011b za\u010dali p\u011bstovat obil\u00ed.<\/p>\n

Vznik zem\u011bd\u011blstv\u00ed byl v\u00fdznamn\u00fdm mezn\u00edkem v rozvoji velk\u00fdch lidsk\u00fdch s\u00eddel a v\u00fdvoji civilizace.<\/p>\n

V\u011bdci se shoduj\u00ed v tom, \u017ee na po\u010d\u00e1tku rann\u00edho driasu do\u0161lo ke zm\u011bn\u011b klimatu, ale rozch\u00e1z\u00ed se ve stanoven\u00ed p\u0159\u00ed\u010din, kter\u00e9 ho vyvolaly.<\/p>\n

D\u0159\u00edve bylo nej\u010dast\u011bj\u0161\u00ed vysv\u011btlen\u00ed pr\u016flom ledov\u00e9 hr\u00e1ze, v d\u016fsledku \u010deho\u017e do Atlantiku proniklo obrovsk\u00e9 mno\u017estv\u00ed sladk\u00e9 vody.<\/p>\n

To p\u0159eru\u0161ilo tepl\u00e9 tropick\u00e9 proudy, co\u017e vedlo k ni\u017e\u0161\u00edm teplot\u00e1m po cel\u00e9 planet\u011b.<\/p>\n

Nyn\u00ed v\u0161ak v\u011bdci z Dartmouth College<\/em> v New Hampshire, veden\u00e9m profesorem Mikula Sharma<\/em> se p\u0159ikl\u00e1n\u00ed k domn\u011bnce, \u017ee zm\u011bnu klimatu zp\u016fsobil asteroid, kter\u00fd narazil do Zem\u011b na po\u010d\u00e1tku mlad\u0161\u00edho dryasu<\/em> v Quebecu.<\/p>\n

Stopy po kr\u00e1teru se nezachovaly, ale v\u011bdci analyzovali kousky, roztaven\u00e9 v pozd\u011bji ztvrdl\u00fdch hornin\u00e1ch, datovan\u00fdch na po\u010d\u00e1tku mlad\u00e9ho dryasu<\/em> v Pensylv\u00e1nii a New Jersey. P\u0159esn\u011b stejn\u00e9 kousky nalezli na jihu kanadsk\u00e9 provincie Quebec. Nejpravd\u011bpodobn\u011bj\u0161\u00ed p\u0159\u00ed\u010dinou jejich vzniku jsou velmi vysok\u00e9 teploty a tlak, co\u017e jsou nej\u010dast\u011bj\u0161\u00ed stopy v oblasti sr\u00e1\u017eky asteroidu se Zem\u00ed.<\/p>\n
