Ososayensi abaholwa nguLava Dahlya ofuywayo abamele isikhungo sePaleontology University baveza izimfihlo zezinambuzane ezinkulu ezivela eminyakeni yobudala. Kungenzeka ukuthi kusetshenziswe lokhu kubonga kwe-DNA yakudala emhlabeni etholakele kwisidumbu sezilwane zasendulo ezitholwe iqhwa eMarzlot yaphakade yaseSiberia.
Abaphenyi bakwazile ukukhipha i-mammoth DNA emazinyweni abomdabu abamele abamele umkhaya wendlovu. Iminyaka yokuthola impahla yofuzo ineminyaka eyi-1,200. Kuze kube yilapho okutholakele kwakamuva kwe-DNA eyaziwayo, i-DNA yehhashi le-prehistoric elakhiwe endaweni yesimanjemanje Yukon (Canada) kubhekwe eminyakeni eyizinkulungwane ezingama-560-780 edlule.
Iqembu laphesheya kososayensi liphinde lahlalisa ukulandelana kwe-DNA kwamasampula amathathu atholakalayo ukuze afunde umndeni wesihlahla sohlu lozalo lwesinambuzane.
Ukuhlukahluka kokuqukethwe kofuzo kuboniswe ukuthi ama-fangs avela kanjani ama-fangs lapho ama-ice ahlanya amakhilomitha amboze iningi le-hemisphere esenyakatho futhi aveze i-okhokho ayengaziwa ngaphambili enyakatho.
"Ngale DNA enkulu, ungakubona ngokuqondile ukuvela kwe-exported iminyaka engaphezu kwesigidi," kusho uGeyline kusuka e-Illinois avela e-Illinois University e-Urbane-Champane Alfred Roca. Izinguquko e-Genome ziyabonakala, yini eyenza ukuthi ziqonde ukuthi kancane kancane ukuvela kwezilwane kuguquka kancane kancane kuphawuleke ngokuphelele yisazi. Izazi ze-paleontologists zeBritish Museum of Natural Science zichaze: I-Arctic Replot Rengzlot igcina amathambo amathambo ayizigidi eziyi-10 ngama-bevnesses. Ngemuva kokukhipha iqhwa, ezinye izidumbu azicekelwa phansi futhi uvolo nezindwangu ziqinile. Kusuka ezintweni ezinjalo, ochwepheshe bese ususa i-DNA ukuze ucwaninge ngocwaningo ukuze ufunde imininingwane eyengeziwe ngempilo nendawo yokuhlala yezimali.
Ukuhlaziywa kwamasampula e-DNA atholwe esidumbu sezilwane zasendulo ezitholakala ensimini yasenyakatho-mpumalanga yeSiberia ngo-1970 kwakhombisa ukuthi ezimbili zazo zingama-steppe Mammoth - Mammuthuthus Trogontherii (Ifomu Lihlala ePleistocene Epoch e-Eurasia). Ukukhula kwe-Steppe Mammoth kwakungamamitha ayi-4 7 kanti ubude bakabhiya babecishe babe ngamamitha ayi-5. I-mammoth enosonga kwakunguMamuthus Primigenius waba ngumnikazi weDNA yesithathu. Iqembu lososayensi lithole ukuthi umuntu oyedwa wezinyathelo ungowase-Steppe Mammoth eqenjini labantu abavela abantu bakhe baphenduka kancane kancane baba uhlobo lweMamuthus Primigenius. Inhloko yomsebenzi kaDkt Dalien ayinqantshisi i-hypothesis mayelana nokuba khona kwezinhlobo ezimbili ezahlukene zezimali.
Njengengxenye yolunye ucwaningo, ochwepheshe e-japanese University Balai bazama "ukubuyela empilweni" izilwane ezinkulu zeqhwa. Babesebenzisa i-DNA yeMammoth ekhonjwe eSiberia cishe iminyaka eyizinkulungwane ezingama-28 ubudala futhi yazisa izinto zofuzo kumaseli e-rodent. Ngenxa yomonakalo omkhulu, izinhlobo zofuzo bezingafaneleki ukusebenza okugcwele - hhayi uphawu olulodwa lomsebenzi wamangqamuzana atholakele lapho kunikezwe isigaba seseli. Uthando Dalien alukholelwa ekusebenzeni kahle kwemizamo yokuvuselela izinambuzane nokungabaza kubhekisele ezivivinyweni ezinjalo.
