Saynisyahannada ay hogaaminayaan hiddo-wadaha Lava Dahlyna oo matalaya bartamaha magaalada Paleonology ee Jaamacadda Stockholm ee Jaamacadda Stockholm ayaa muujisay sirta mammoths mammoth-ka ee da'da barafka. Way suurtogal ahayd in la hirgaliyo tan Thanks to kii ugu yaraa DNA ee dunida laga helay bakhtiga xayawaanada qadiimka ah ee laga helay barafoobay ee la qaboojiyey daawada Siber ee weligiis ah.
Baarayaasha waxay awoodeen inay soo saaraan mammth DNA ilkaha asaliga ah oo ah wakiillo ka mid ah wakiillo ka mid ah qoyska maroodiga. Da'da laga helay maaddada hidda-wadaha waxay leedahay ilaa 1,200 sano. Ilaa aasaaskii ugu dambeeyay ee ugu caansan DNA-da caanka ah ee DNA, DNA ee fardaha prehistoric ee ku sugan dhulka Yukon ee casriga ah (Kanada) waxaa loo tixgeliyey 560-780 kun oo sano ka hor.
Kooxda caalamiga ah ee saynisyahannada ayaa dib u dhigay taxanaha DNA ee seddex saamba oo la heli karo si ay u bartaan qoyska abtirsiinta abtirsiinta ee Mammoth.
Kala duwanaanshaha maaddada hidda-wadaha ayaa muujisay sida 10-ton oo ay jiraan hal abuurka fangaga la soo rogay markii gaashaafka barafka qaro weyn ka daboolay waqooyiga hemisphere oo uu shaaca ka qaaday abtirsiinyo hore oo mammyo ah oo marwalba ka warwareegayey waqooyiga Ameerika.
"Marka loo eego DNA-dani, si toos ah waad u arki kartaa isbeddelka in ka badan hal milyan oo sano," ayuu yidhi hidda-wadaha oo ka socda Jaamacadda Illinois ee magaalada Urbane-Champane Alfred Roca. Isbedelada ku dhaca Genome waa la arki karaa, waxa suurta galka ah in la fahmo sida ay u socdaan hal nooc oo noocyo ah ay si tartiib tartiib ah u beddelato si buuxda oo ay u kala duwan yihiin khabiir. Dhakhaatiirta ku takhasusay ee matxafka Ingiriiska ee sayniska dabiiciga ah ee sayniska dabiiciga ah ayaa sharraxay: Ku duqeynta Merzlot weligeed ah ee Merzlot weligeed ah ilaa 10 milyan oo qalfoof oo ka mid ah kooxda leh ee galka. Ka dib markii la soo saaro baraf, qaar ka mid ah modes-ka lama hariyo iyo dhogorta iyo dharka ayaa ah mid aan caadi ahayn. Laga soo bilaabo agabyada noocaas ah, takhasusleyaasha oo ka saar DNA si cilmi-baaris dheeraad ah loo sameeyo si wax looga barto tafaasiisha dheeraad ah ee ku saabsan nolosha iyo deegaanka ee mammths.
Falanqaynta muunadaha DNA ee laga soo helay bakhtiga xayawaanka hore ee laga helay dhulka waqooyi-bari Siberiya 1970 Koritaanka steppe mammoth wuxuu ahaa 4 7 mitir iyo dhererka biirku wuxuu ahaa ku dhawaad 5 mitir. Hooyooyinka dhogorta leh ee loo yaqaan 'mammuttus prigenius' prigenius prim primsus prigenius wuxuu u rogay inuu noqdo milkiilaha DNA-da saddexaad. Kooxda saynisyahannadu waxay ogaadeen in hal steppe mammoth ay ka tirsan tahay kooxda isbedelka kooxda ka mid ah shaqsiyadeedu si tartiib tartiib ah u beddeleen nooc ka mid ah mammamus prigenius. Madaxa shaqada Dr. DALIN ma diido fikirka ku saabsan jiritaanka laba nooc oo ah mammoths.
Iyada oo qayb ka ah daraasad kale, khubaro ku sugan Jaamacadda Jabbaan ee Jabbaan ayaa isku dayay inay "ku laabtaan nolosha" xayawaanka weyn ee barafka da'da. Waxay u adeegsan jireen DNA-da Mammoth ee lagu tilmaamay Siberia qiyaastii 28 kun sano jir waxayna soo bandhigtay walxaha hidaha ee unugyada jiidaha. Burbur daran awgood, hiddo-wadaha kama aysan habooneyn shaqa-dhameystiran - oo aan ahayn hal calaamad oo ah nashaadka molikalar ayaa la helay in Qeybta Guri lasiiyay. Jacaylka Dalien ma aaminsana in wax ku oolnimada isku dayga lagu soo nooleeyo mammoths oo ay shaki ku tahay loola jeedo tijaabooyinka noocan oo kale ah.
