Wofufuza golide ku Klondike adapeza zosowa - mbuzi yakhanda yosungidwa bwino, MediaPortal idanenanso pa Juni 25.
Zotsalira za nyama zoyamwitsa zakhala m'nthaka yachisanu ya Yukon Territory ya Canada kwa zaka zoposa 30,000.
Thupi la mummified kuchokera ku Ice Age ndi pafupifupi 1 mita ndi 40 centimita kutalika.
Nyamayi yaing’ono yotchedwa woolly mammoth imaganiziridwa kuti inafa patatha masiku 30 kuchokera pamene inabadwa
Asayansi atulutsa DNA yakale kwambiri yodziwika bwino ku mammoth omwe amakhala kumpoto chakum'mawa kwa Siberia zaka 1.2 miliyoni zapitazo, Reuters idatero mu February 2021.
Mano amene DNA inatengedwa ndi kutsatizana amachokera ku mammoths atatu. Iwo amasungidwa mu permafrost. zotsalira zina zinapezeka m'zaka za m'ma 1970, koma luso lamakono lokha lapanga zotheka kuchotsa DNA.
Wakale kwambiri wa mano atatu adapezeka pafupi ndi mtsinje wa Krestovka. Ndi zaka 1.2 miliyoni. Wachiwiri wa chigwa cha Adicha ndi pafupifupi miliyoni imodzi, zaka 1.2 miliyoni. Wachitatu anali pafupi ndi mtsinje wa Chukocha. Iye ndiye wamng'ono kwambiri - pafupifupi zaka 700,000.
“Iyi ndiye DNA yakale kwambiri yomwe yapezeka,” anatero katswiri wokhulupirira za chisinthiko Love Dalen wa pa Center for Paleogenetics ku Sweden.
Mpaka pano, DNA yakale kwambiri inali ya hatchi yomwe inkakhala ku Canada Yukon zaka 700,000 zapitazo.
Poyerekeza, mitundu yathu ya Homo sapiens idawoneka zaka 300,000 zapitazo.
DNA yotengedwa yasinthidwa kukhala tiziduswa tating'ono kwambiri, ndipo akatswiri adatsata magawo mamiliyoni aafupi kwambiri kuti alumikizane ndi ma genome.
Chidziwitso chochuluka cha zolengedwa zakale zimachokera ku kafukufuku wa zinthu zakale. Komabe, pali malire kwa iwo, makamaka kugwirizana kwa majini ndi makhalidwe. DNA yakale ikhoza kudzaza mipata yotereyi.
Akatswiri ayerekezera DNA yakale kwambiri imeneyi ndi chitsanzo cha nyama yaikulu kwambiri imene inalipo kale kwambiri. Mammoth ochokera ku Krestovka ndi ochokera ku mzere wosadziwika mpaka pano, wolekanitsidwa zaka zoposa 2 miliyoni zapitazo kuchokera ku zomwe zinapangitsa kuti mammoth awonekere. Zikuoneka kuti nyama zazikuluzikuluzi zinali zoyamba kusamuka ku Siberia kupita ku North America kudera lomwe linalipo panthawiyo pafupifupi zaka 1.5 miliyoni zapitazo. Mbalame zotchedwa woolly mammoth zinasamuka zaka 400,000 mpaka 500,000 zapitazo.
