stdClass Object ( [id] => 1154524 [title] => Pokušali su riješiti višestoljetnu zagonetku: znanstvenici uvjereni da su odgonetnuli pravu svrhu kipova s Uskršnjeg otoka [alias] => pokusali-su-rijesiti-visestoljetnu-zagonetku-znanstvenici-uvjereni-da-su-odgonetnuli-pravu-svrhu-kipova-za-uskrsnjeg-otoka [catid] => 423 [published] => 1 [introtext] => [fulltext] =>

Priča o preživljavanju ranih stanovnika Uskršnjeg otoka dugo je golicala maštu znanstvenika. Sada istraživači vjeruju da su otkrili kako je drevna civilizacija uspjela zadržati svoje društvo unatoč nedostatku slatke vode, piše National Geographic. 

Europski zapisi iz 18. stoljeća opisuju te otočane kao bića koja mogu piti morsku vodu bez posljedica – iako danas znamo da ljudski organizam ne može preraditi veliku koncentraciju morske vode. Do 1887. godine stanovništvo Uskršnjeg otoka značajno se smanjilo zbog trgovine robljem i raznih bolesti, čime je eliminirana svaka mogućnost saznanja usmene povijesti otočana.

Znanstvenici su proveli dvije studije terena diljem otoka. Uz iznimku dva teško dostupna jezera i potoka koji se često pretvara u močvaru, znanstvenici su otkrili da tamo nema značajan izvor pitke vode.

- Porozno vulkansko tlo brzo upija kišu, što rezultira nedostatkom potoka i rijeka, rekao je voditelj istraživanja Carl Lipo.

Vjeruje se da su visoki kipovi nagovještavali izlijevanje podzemne vode u ocean, omogućujući stanovnicima da uklone slatku vodu s površine, grade rovove i druge obalne prijelaze. Ove zalihe vode pomogle bi stanovnicima Rapa Nuija u sušnim razdobljima.

Međutim, drugi istraživači smatraju da su male cisterne, koje su pronađene na otoku, služile za prikupljanje oborina. Carl Lipo kaže da kada bi se te cisterne koristile za skupljanje kišnice, onda bi bile puno veće. Ovi spremnici mogu skupiti dvije do četiri litre vode, a s padalinama od 1240 milimetara godišnje i stopom isparavanja vode, spremnici bi vjerojatno bili održivi izvor samo jednu trećinu godine.

U budućim istraživanjima, tim se nada da će razumjeti kako je dostupnost pitke vode na određenim mjestima povezana s izgradnjom kipova.

Priča o preživljavanju ranih stanovnika Uskršnjeg otoka dugo je golicala maštu znanstvenika. Sada istraživači vjeruju da su otkrili kako je drevna civilizacija uspjela zadržati svoje društvo unatoč nedostatku slatke vode, piše National Geographic. 

Europski zapisi iz 18. stoljeća opisuju te otočane kao bića koja mogu piti morsku vodu bez posljedica – iako danas znamo da ljudski organizam ne može preraditi veliku koncentraciju morske vode. Do 1887. godine stanovništvo Uskršnjeg otoka značajno se smanjilo zbog trgovine robljem i raznih bolesti, čime je eliminirana svaka mogućnost saznanja usmene povijesti otočana.

Znanstvenici su proveli dvije studije terena diljem otoka. Uz iznimku dva teško dostupna jezera i potoka koji se često pretvara u močvaru, znanstvenici su otkrili da tamo nema značajan izvor pitke vode.

- Porozno vulkansko tlo brzo upija kišu, što rezultira nedostatkom potoka i rijeka, rekao je voditelj istraživanja Carl Lipo.

Vjeruje se da su visoki kipovi nagovještavali izlijevanje podzemne vode u ocean, omogućujući stanovnicima da uklone slatku vodu s površine, grade rovove i druge obalne prijelaze. Ove zalihe vode pomogle bi stanovnicima Rapa Nuija u sušnim razdobljima.

Međutim, drugi istraživači smatraju da su male cisterne, koje su pronađene na otoku, služile za prikupljanje oborina. Carl Lipo kaže da kada bi se te cisterne koristile za skupljanje kišnice, onda bi bile puno veće. Ovi spremnici mogu skupiti dvije do četiri litre vode, a s padalinama od 1240 milimetara godišnje i stopom isparavanja vode, spremnici bi vjerojatno bili održivi izvor samo jednu trećinu godine.

U budućim istraživanjima, tim se nada da će razumjeti kako je dostupnost pitke vode na određenim mjestima povezana s izgradnjom kipova.

Priča o preživljavanju ranih stanovnika Uskršnjeg otoka dugo je golicala maštu znanstvenika. Sada istraživači vjeruju da su otkrili kako je drevna civilizacija uspjela zadržati svoje društvo unatoč nedostatku slatke vode, piše National Geographic. 

Europski zapisi iz 18. stoljeća opisuju te otočane kao bića koja mogu piti morsku vodu bez posljedica – iako danas znamo da ljudski organizam ne može preraditi veliku koncentraciju morske vode. Do 1887. godine stanovništvo Uskršnjeg otoka značajno se smanjilo zbog trgovine robljem i raznih bolesti, čime je eliminirana svaka mogućnost saznanja usmene povijesti otočana.
