J\u00e4\u00e4ajal elas Euraasias suuri ja karvaseid loomi. \u00dcks neist oli karvane ninasarvik.<\/p>\n

N\u00fc\u00fcd on Rootsi teadlastel korda l\u00e4inud j\u00e4rjeldada ja l\u00e4bi uurida \u00fche enam kui 14 tuhat aastat tagasi elanud karvase ninasarviku genoom, kelle hunt oli \u00e4ra s\u00f6\u00f6nud. Hunt leiti Siberi igikeltsast, ninasarvikuproov saadi hundi k\u00f5hust.<\/p>\n

S\u00f3lveig Gu\u00f0j\u00f3nsd\u00f3ttir ja Edana Lord Stockholmis asuvast Paleogeneetika Keskusest, mida haldavad \u00fcheskoos Stockholmi \u00dclikool ja Rootsi Loodusmuuseum, kirjutavad koos kaasautoritega ajakirjas Genome Biology and Evolution<\/a>, et nende uuringu j\u00e4rgi p\u00fcsisid karvased ninasarvikud geneetilises m\u00f5ttes tervetena kuni j\u00e4\u00e4aja l\u00f5puni. Siis surid nad t\u00f5en\u00e4oliselt v\u00e4lja arvukuse kiire languse tagaj\u00e4rjel, mitte aegam\u00f6\u00f6da alla k\u00e4ies.<\/p>\n

Eales varem ei ole teadlased j\u00e4rjeldanud j\u00e4\u00e4egse looma genoomi, mis on k\u00e4tte saadud kiskja k\u00f5hust. Karvase ninasarviku genoome on siiski juba varemgi uuritud, kuid n\u00fc\u00fcd anal\u00fc\u00fcsitu on neist k\u00f5igist noorem.<\/p>\n

<\/p>\n

Teadlased k\u00f5rvutasid hundi k\u00f5hust p\u00e4rinevat karvase ninasarviku genoomi kahe vanema, umbes 18 tuhande ja 49 tuhande aasta vanuse genoomiga, et aimu saada, kuidas on nende loomade geneetiline mitmekesisus aegam\u00f6\u00f6da muutunud ja kui palju on geenides mutatsioone olnud.<\/p>\n

Selgus, et v\u00e4ljasuremise eel ei olnud genoomi sugenenud sugulussigimise m\u00e4rke, mis vihjanuksid arvukuse suurele langusele. Ka mingeid muid aeglasele allak\u00e4igule viitavaid m\u00e4rke genoomis ei paistnud.<\/p>\n

T\u00f5en\u00e4oliselt elasid karvased ninasarvikud r\u00f5\u00f5msalt ja arvukalt j\u00e4\u00e4aja l\u00f5puni v\u00e4lja, kuid j\u00e4\u00e4aja j\u00e4rgse j\u00e4rsu soojenemisega ei tulnud enam toime.<\/p>\n

Ka tervelt 15 tuhande aasta jooksul p\u00e4rast esimeste inimeste ilmumist Siberisse p\u00fcsis karvaste ninasarvikute arv stabiilselt suhteliselt suur, mist\u00f5ttu ei saa inimesi nende liigses k\u00fcttimises arvatavasti s\u00fc\u00fcdistada.<\/p>\n

Koopaseintele on Euraasia \u00fcrginimesed karvaste ninasarvikute \u00fclesjoonistusi teinud, mis viitab, et toekaks toiduks nende suurte rohus\u00f6\u00f6jate loomade liha inimestele oli.<\/p>\n
