Ikati elihle manje eliphumule ngokuthula kusofa wethu, lelo elisibuka ngalawo mehlo amnandi futhi athambile ukuthi ufuna ukuwadla ngokuqabula, futhi aqala ukuhlanza njalo lapho siphulula umhlane noma ikhanda lawo, Unokhokho ababehamba ngemikhumbi yamaViking.
Futhi hhayi lokho kuphela, kepha yize kuze kube manje bekukholelwa ukuthi UFelis catus Babeshiye iGibhithe beyohlukanisa umhlaba wonke ngokunwetshwa okukodwa, empeleni kwakungafani nalokho. Thola amakati alinqobe kanjani izwe.
Ngenxa yokwehla kwezindleko zokuhlaziywa kwe-DNA, abacwaningi bangafunda imininingwane eminingi mayelana nokwedlule kwalezi zilwane ezinhle futhi eziyindida. Ngakho-ke, isazi sezakhi zofuzo u-Eva-Maria Geigl, waseJacqued Monod Institute eParis, wenza ucwaningo olumangazayo, lapho kwembulwa khona ukuthi amakati amancane ahambisana namaViking nabathengisi ezikebheni zabo ukufinyelela, ngaleyo ndlela, ukufinyelela ezinye izingxenye zomhlaba futhi, ngenhlanhla, uthathe uhambo olwandle, into ebingaziwa ngokuphelele kuze kube yileso sikhathi.
UGeigl neqembu lakhe, ihlaziye i-DNA ye-mitochondrial - edluliselwa isuka kumama iye enganeni ingashintshiwe - isuka kumakati angama-209 asekhaya afakwa ezindaweni ezingama-30 zemivubukulo eYurophu, e-Afrika naseMpumalanga Ephakathi. Lezi zilwane zithatha umlando wesintu kusukela ekudalweni kwezolimo kuze kube sekhulwini le-18.
Umphumela kumele ukuthi wabamangaza njengoba nakanjani uzokumangaza: amakati ahlukanisa umhlaba ngamagagasi amabili. Okokuqala kwenzeka lapho ezolimo zivela empumalanga yeTurkey naseMedithera, lapho kuhlala khona okhokho bamakati asekhaya.. Kusolwa ukuthi okusanhlamvu kudonswe ngamagundane, nalokhu kuhehe amakati, aqale ukubukwa kahle ngabalimi.
Ukunwetshwa kwesibili kwenzeka eminyakeni eyizinkulungwane ezimbalwa kamuva, eBulgaria, eTurkey, nase-sub-Saharan Africa, phakathi kwekhulu lesine leminyaka BC. C. kanye nesine d. C. Ngaleso sikhathi amatilosi kungenzeka ukuthi ayeselibonile ikati, umngane ababemdinga kakhulu ukuvimba amagundane. Eqinisweni, ikati eline-DNA yemitochondrial yaseGibhithe latholakala endaweni yamaViking enyakatho neJalimane, eliphakathi kuka-700 no-1000 AD.
Ngakho-ke, ukufuya ikati akuzange kwenzeke eminyakeni engama-4000 edlule njengoba bekukholelwa, kepha okungenani akwenzeki iminyaka 6000.
Ucwaningo lushicilelwe kumagazini i-Nature, futhi ungalufunda ngokwenza chofoza lapha.
