Delfiinid, kellel on teiste delfiinide seas rohkem s\u00f5pru, p\u00fcsivad kauem noored kui \u00fcksildasemad isendid.<\/p>\n

Niisugusele j\u00e4reldusele on oma uurimist\u00f6\u00f6 p\u00f5hjal j\u00f5udnud Austraalia teadlased, kes pakuvad india ookeani silmikdelfiinide kohta saadud tulemusi lugeda ajakirjas Communications Biology<\/a>.<\/p>\n

Delfiinid on \u00fchiselulised ja m\u00e4ngulustilised loomad, kuid ajapikku j\u00e4\u00e4vad vanemaks nemadki. Vanematel delfiinidel j\u00e4\u00e4b energiat v\u00e4hemaks, liikumine j\u00e4\u00e4b aeglasemaks, silman\u00e4gemine t\u00f6ntsimaks ja nahk laigulisemaks.<\/p>\n

<\/p>\n

Livia Gerber Uus-L\u00f5una-Walesi \u00dclikoolist Sydneys ja ta kolleegid anal\u00fc\u00fcsisid delfiinide vananemisn\u00e4hte rakuproovide p\u00f5hjal.<\/p>\n

Nii nad tuvastasidki, et neil isastel india ookeani silmikdelfiinidel, kes suhtlevad teiste omasugustega rohkem, on vananemisn\u00e4hte rakkudes n\u00e4ha v\u00e4hem kui neil, kes sagedamini omaette hoiavad.<\/p>\n

On teada, et isaste delfiinide vahel v\u00f5ib s\u00f5brasuhe p\u00fcsida aastak\u00fcmneid. Seep\u00e4rast keskendusidki Gerber ja ta kaaslased just isaseid delfiine uurima. Emaste delfiinide vahel on s\u00f5brannasuhted enamasti l\u00fchemat laadi ja l\u00f6\u00f6vad \u00f5itsele eelk\u00f5ige \u00fcheealiste j\u00e4rglaste olemasolul.<\/p>\n

Teadlased l\u00f5id endale k\u00f5igepealt L\u00e4\u00e4ne-Austraalias Shark Bays elutseva delfiiniasurkonna elust pildi ette. Nad j\u00e4lgisid aastate pikku muu hulgas seda, millistele isenditele meeldis \u00fcheskoos saaki jahtida, laineis h\u00fcpelda v\u00f5i puhata.<\/p>\n

Siis v\u00f5tsid nad delfiinidelt proove ja vaatasid DNA markerite p\u00f5hjal, mis aega n\u00e4itas rakkude sees niinimetatud epigeneetiline kell, mis osutab \u00fcsna h\u00e4sti ka looma terviseseisundile ja vananemisilmingutele. Nahakoeproove v\u00f5eti ja anal\u00fc\u00fcsiti 38 delfiinilt.<\/p>\n

Gerber ja ta kolleegid oletavad, et suhtlusaltimad delfiinid vananevad aeglasemalt seep\u00e4rast, et nende elu on lihtsam kui \u00fcksiklastel: jahti pidada on t\u00f5husam s\u00f5braga \u00fcheskoos, ohtu sattudes v\u00f5ib s\u00f5brast abi olla, ja laintes hullates on r\u00f5\u00f5mu ja l\u00f5\u00f5gastust ka kindlasti rohkem, kui s\u00f5ber on seltsis.<\/p>\n

Gerberi s\u00f5nul v\u00f5iks samalaadseid tulemusi saada k\u00fcllap laiendada ka teistele liikidele.<\/p>\n

Ka inimestel tasuks m\u00f5nikord m\u00f5elda kasv\u00f5i sedapidi, et meie \u00fchiselulised vajadused on samas v\u00f5ib-olla suuresti \u00fchtlasi ka t\u00e4iesti elulised vajadused.<\/p>\n
