Uhlalutyo olutsha lwe-DNA luyedwa kwi-sases yakudala lezinja ibonise ukuba bafudukele eSiberia bamalunga namawaka amathathu eminyaka eyadlulayo. Ukusuka apha, basasaza ngasentshona nasempuma, kunye neenkosi zabo ezisandul 'ukufumana izidlo zabo ezisandul' ukufunyanwa bawele i-harting qhwa emva koko bangena eMelika. Lo mfanekiso onjalo uchaza ababhali benqaku elitsha elipapashwe kwimagazini ye-PNAs.
Ngapha koko, izinja zaba zizilwanyana zasekhaya, kodwa iinkcukacha ezininzi zale nkqubo zihlala ziyimfihlakalo. I-genome yawo namhlanje ididekile kangangokuba ukuzama ukulandelela imvelaphi yabantu basekhaya abonisa ukuba i-china, emva koko i-Yurope kwaye inikezele ngamawaka ali-10 ukuya kwengamawaka amawaka, kwaye ezinye iingcali zide zikholelwe ukuba kube kanye.
Ingxaki kukuba iingcali zihlala zingakwazi ukwahlula intsalela yezinja ze-pecetocene ezivela kwiingcuka, ezazingafani nangakumbi nge-anatomically okanye i-genet. Ke ngoko ababhali bomsebenzi omtsha bajonga indalo yezinja ngokuhambelana nendalo yakubahlali baseSiberia, iBeria naseMntla Merika. Izazinzulu zifumanise ukuba amaqela okuqala abazingeli bezinja avela ekukhanyeni okutsha ezili-15 eyadlulayo, kwaye i-Prehister inokuthi ilandelwe de ibe seSiberia, kumawaka angama-22.8 kwiminyaka edlulileyo.
Yayilixesha lobuninzi bokusijonga kokugqibela, xa yonke indawo ethathwayo ithathelwa ingqalelo ebomini, kubanda kwaye yomile. Zaziimeko ezinokunyanzela abantu beengcuka zokugcina abantu ukuba bafumane amathambo kunye nemanyano, kwaye basebenzisana ngakumbi nabo. Ixesha elingaphezulu, oku kukhokelele ekuphuhlisweni kobudlelwane obusondeleyo kunye notshintsho lwezilwanyana zasendle kwizilwanyana ezitsha, esele zikhuselwe ekhaya.
Ukusuka apha, indawo yabo yokuhlala yaqala ukuya ngasentshona nasempuma, ukuya eMelika. "Kudala sazi ukuba abantu bokuqala kwilizwekazi sele bephumelele kakhulu itekhnoloji yokuzingela," utshilo uDavid Melzer (uDavid Melzer), omnye wababhali abatsha sebenza. "Izinja ezihamba nabo kuba imbonakalo esenzeka kwihlabathi elitsha inokuba yinxalenye efanayo yale nkcubeko, njengezixhobo zamatye ababethwa ngabantu."
