Hobit z Floresu: Nov\u00e9 d\u016fkazy znovu otev\u00edraj\u00ed debatu<\/h2>\n\n

Objev a prvn\u00ed zji\u0161t\u011bn\u00ed<\/h2>\n\n

V roce 2003 byl na indon\u00e9sk\u00e9m ostrov\u011b Flores u\u010din\u011bn pr\u016flomov\u00fd objev: poz\u016fstatky d\u00e1vn\u00fdch lid\u00ed, kte\u0159\u00ed byli n\u00e1padn\u011b mal\u00e9 velikosti. V\u011bdci, kte\u0159\u00ed tento objev u\u010dinili, do\u0161li k z\u00e1v\u011bru, \u017ee tyto poz\u016fstatky pat\u0159\u00ed k nov\u00e9mu druhu Homo, kter\u00e9mu dali p\u0159ezd\u00edvku \u201ehobiti z Floresu\u201c. Tento objev byl oslavov\u00e1n jako jeden z nejd\u016fle\u017eit\u011bj\u0161\u00edch v oblasti lidsk\u00e9 evoluce za v\u00edce ne\u017e stolet\u00ed.<\/p>\n\n

Kontroverze a debata<\/h2>\n\n

Po\u010d\u00e1te\u010dn\u00ed zji\u0161t\u011bn\u00ed se v\u0161ak setkala se skepticismem n\u011bkter\u00fdch v\u011bdc\u016f. N\u011bkte\u0159\u00ed tvrdili, \u017ee jedna jedin\u00e1 lebka nen\u00ed dostate\u010dn\u00fdm d\u016fkazem pro stanoven\u00ed nov\u00e9ho druhu, zat\u00edmco jin\u00ed nazna\u010dovali, \u017ee mal\u00e1 velikost lebky mohla b\u00fdt sp\u00ed\u0161e v\u00fdsledkem nemoci ne\u017e jedine\u010dn\u00e9ho evolu\u010dn\u00edho rysu.<\/p>\n\n

Nov\u00fd v\u00fdzkum znovu otev\u00edr\u00e1 debatu<\/h2>\n\n

Nyn\u00ed dva nov\u00e9 \u010dl\u00e1nky publikovan\u00e9 v\u011bdci z Penn State a dal\u0161\u00edch instituc\u00ed znovu otev\u0159ely debatu o hobitovi z Floresu. V jednom z t\u011bchto \u010dl\u00e1nk\u016f v\u011bdci tvrd\u00ed, \u017ee lebka z Floresu nep\u0159edstavuje nov\u00fd druh, ale sp\u00ed\u0161e star\u00e9ho jedince s Downov\u00fdm syndromem.<\/p>\n\n

D\u016fkazy pro Down\u016fv syndrom<\/h2>\n\n

V\u011bdci poukazuj\u00ed na n\u011bkolik d\u016fkazn\u00edch lini\u00ed, kter\u00e9 podporuj\u00ed jejich hypot\u00e9zu. Zaprv\u00e9 si v\u0161imli, \u017ee lebe\u010dn\u00ed m\u011b\u0159en\u00ed a rysy lebky z Floresu odpov\u00eddaj\u00ed modern\u00edm projev\u016fm Downova syndromu. Krom\u011b toho jsou krat\u0161\u00ed stehenn\u00ed kosti jedince tak\u00e9 v souladu s Downov\u00fdm syndromem.<\/p>\n\n

P\u0159ekrucovan\u00e1 velikost lebky<\/h2>\n\n

V\u011bdci tak\u00e9 tvrd\u00ed, \u017ee p\u016fvodn\u00ed zpr\u00e1va o poz\u016fstatc\u00edch z Floresu zveli\u010dovala drobnou velikost lebky. Provedli vlastn\u00ed m\u011b\u0159en\u00ed a zjistili, \u017ee lebka je ve skute\u010dnosti v\u011bt\u0161\u00ed, ne\u017e bylo d\u0159\u00edve uvedeno, a \u017ee spad\u00e1 do p\u0159edpokl\u00e1dan\u00e9ho rozsahu pro modern\u00edho \u010dlov\u011bka s Downov\u00fdm syndromem ze stejn\u00e9ho zem\u011bpisn\u00e9ho regionu.<\/p>\n\n

V\u00fd\u0161ka a vzr\u016fst<\/h2>\n\n

V\u011bdci tak\u00e9 poukazuj\u00ed na to, \u017ee kostra z Floresu pat\u0159ila jedinci, kter\u00fd byl vysok\u00fd n\u011bco m\u00e1lo p\u0159es 1,20 m, co\u017e je srovnateln\u00e9 s v\u00fd\u0161kou n\u011bkter\u00fdch modern\u00edch lid\u00ed na Floresu. To d\u00e1le nazna\u010duje, \u017ee jedinec nemusel b\u00fdt \u010dlenem odli\u0161n\u00e9ho druhu, ale sp\u00ed\u0161e \u010dlov\u011bkem s genetickou poruchou.<\/p>\n\n

Odpor v\u016f\u010di hypot\u00e9ze<\/h2>\n\n

Navzdory d\u016fkaz\u016fm p\u0159edlo\u017een\u00fdm v nov\u00fdch \u010dl\u00e1nc\u00edch z\u016fst\u00e1vaj\u00ed n\u011bkte\u0159\u00ed v\u011bdci v\u016f\u010di \u201ehypot\u00e9ze nemocn\u00e9ho hobita\u201c odoln\u00ed. Tvrd\u00ed, \u017ee poz\u016fstatky z Floresu st\u00e1le vykazuj\u00ed jedine\u010dn\u00e9 rysy, kter\u00e9 nelze pln\u011b vysv\u011btlit Downov\u00fdm syndromem.<\/p>\n\n

Implikace pro lidskou evoluci<\/h2>\n\n

Debata o hobitovi z Floresu m\u00e1 d\u016fle\u017eit\u00e9 d\u016fsledky pro na\u0161e ch\u00e1p\u00e1n\u00ed lidsk\u00e9 evoluce. Pokud je hobit z Floresu skute\u010dn\u011b \u010dlov\u011bkem s Downov\u00fdm syndromem, nazna\u010dovalo by to, \u017ee tento stav je v lidsk\u00fdch populac\u00edch p\u0159\u00edtomen mnohem d\u00e9le, ne\u017e se d\u0159\u00edve myslelo. Krom\u011b toho by to zpochybnilo tradi\u010dn\u00ed pohled na lidskou evoluci jako na line\u00e1rn\u00ed postup od men\u0161\u00edch k v\u011bt\u0161\u00ed druh\u016fm.<\/p>\n\n
