Baare dahab ah oo ku sugan Klondike ayaa la kulmay helitaan naadir ah - mammoth dhallan oo aad loo ilaaliyo, MediaPortal ayaa werisay Juun 25.
Hadhaaga naasleyda ayaa ku sii jiray ciidda barafsan ee Yukon Territory Canadian in ka badan 30,000 oo sano.
Jirka mummeedka laga soo bilaabo xilligii Barafka wuxuu dhererkiisu yahay 1 mitir iyo 40 sentimitir.
Naasaha dhogorta yar ayaa loo malaynayaa inuu dhintay 30 maalmood ka dib dhalashada
Saynis yahanada ayaa ka soo saaray DNA-gii ugu da'da weynaa ee loo yaqaan molars of mammoth ku noolaa waqooyi bari ee Siberiya 1.2 milyan sano ka hor, Reuters ayaa werisay Febraayo 2021.
Ilkaha laga soo saaray DNA-da oo la isku xigxigay waxay ka soo jeedaan saddex mammoths. Waxay ku kaydsan yihiin permafrost-ka. Qaar ka mid ah haraaga ayaa la helay 1970-meeyadii, laakiin tignoolajiyada casriga ah oo kaliya ayaa suurtagalisay in la soo saaro DNA-da.
Midka ugu da'da weyn ee saddexda ilig ayaa laga helay agagaarka wabiga Krestovka. Waa 1.2 milyan oo sano. Kan labaad ee dooxada Adicha waa qiyaastii hal milyan, 1.2 milyan sano. Midka saddexaad wuxuu u dhawaa webiga Chukocha. Isagu waa kan ugu yar - qiyaastii 700,000 oo sano.
"Tani waa DNA-da ugu da'da weyn ee la helo," ayuu yiri hidde-yaqaanka korriinka ee Love Dalen oo ka tirsan xarunta Paleogenetics ee Iswidhan.
Ilaa hadda, DNA-da ugu da'da weyn waxay ka timid faras ku noolaa Yukon Canadian qiyaastii 700,000 oo sano ka hor.
Marka la barbardhigo, noocyadayaga Homo sapiens waxay soo baxeen qiyaastii 300,000 oo sano ka hor.
DNA-da la soo saaray ayaa hoos loo dhigay qaybo aad u yaryar, khubaradu waxay isku dayeen malaayiin qaybood oo aad u gaaban si ay isugu xidhaan genome-yada.
Inta badan aqoonta makhluuqa taariikhiga ka hor waxay ka timaadaa cilmi-baadhista fosil. Si kastaba ha ahaatee, waxaa jira xad iyaga u gaar ah, gaar ahaan xidhiidhada hidde iyo sifooyinka. DNA-da qadiimiga ah waxay buuxin kartaa daldalooladaas.
Khubaradu waxay is barbar dhigeen DNA-gan ugu qadiimiga ah iyo muunadda naasaha oo noolaa wakhti hore. Naasaha Krestovka wuxuu ka soo jeedaa nasab aan ilaa hadda la garanayn, oo laga soocay in ka badan 2 milyan oo sano ka hor middii keentay muuqaalka naasaha dhogorta leh. Mammoths-yadani waxay u muuqdaan inay ahaayeen kuwii ugu horreeyay ee ka soo haajiray Siberiya una guuray Waqooyiga Ameerika dhul-beereed markaas jiray qiyaastii 1.5 milyan oo sano ka hor. Mammoths dhogorta leh ayaa haajiray 400,000 ilaa 500,000 sano ka hor.
