Abaphandi bahlaluthwe iimeko zokuphila zabantu bamandulo baseNtshona Yurophu kwi-vestocetocene
Abasebenzi beZiko leSizwe kuPhando lwaBantu kunye neYunivesithi yaseCologne batyhila ukuzinza kwamaqondo obushushu asezantsi nangaphandle kwemithombo yobushushu. Ngale nto, iingcali zihlalutya iimeko zemozulu zexesha le-vesistocene. Iziphumo zomsebenzi zapapashwa kwi-jernay yejenali yokuzivelela komntu.
Ixesha le-Pleistocene ephakathi, elihlala lineminyaka eyi-125-780 leminyaka eyadlulayo, iphawuleka ngokuguquguquka kwe-vimotic fihlotic, kunye nezigaba ezipholileyo. Abaphandi basebenzise iimephu ze-paleotheral ukumisela ulawulo lobushushu apho oookhokho bomntu banamhlanje banyanzelwa ukuba baphile ngexesha lezigaba ezibandayo. Izazinzulu zikwazile ukumisela urhulumente wobushushu kwintsimi yeziza ezingama-68 apho ubukho bomntu wakudala wabhaliswa khona.
Ukwenza imodeli yokulinganisa kuvumela izazinzulu ukuba ziqikelele ukuba zilungelelanise zookhokho bookhokho kubantu. Imodeli enjalo ingenisa ilahleko yobushushu ibonwa ngexesha lokulala. Uhlalutyo lubonise ukuba abantu bade bakwazi ukumelana namaqondo obushushu aphantsi kakhulu kungekuphela nje ngexesha lezigaba zeguri, kodwa nakwimeko yemozulu ethambileyo.
Imodeli yemathematics incede izazinzulu ukuba ziphonononge ukusebenza kwezicwangciso-qhinga ezibini ezijolise ekulweni ukubanda. Ke, uvavanyo lwempembelelo yokufaka i-insulation yekhava yoboya, i-lipid ye-lipid ye-lipid, kunye ne-fiend yesizukulwana ngenxa yeenkqubo zeMetabolic emzimbeni. Imodeli ithathe i-akhawunti yokulahleka kobushushu ngenxa ye-gust moya. Yajika ukuba ihlawule umda we-metabolic yokuphendula yemetabolic kubusuku, abantu bamandulo balala, basongelwe ngoboya, kwaye bafumana iindawo ezikhuselweyo zomoya.
Kwangoko, inkonzo yeendaba eziphambili ixelwe ukuba izazinzulu zikwazile ukumisela esona sizathu sokwaluphala lobuchopho.
