<prompt> Fingqa isihloko: Umhlathi womhlathi osanda kutholakala wembula ukuthi okhokho bethu bokuqala babantu bavela e - Afrika cishe eminyakeni eyizigidi ezingu - 2,8 edlule - eminyakeni engu - 400 000 ngaphambili kunalokho obekucatshangwa ngaphambili. Umhlathi ongaphelele, owatholakala esifundeni sase-Afar e-Ethiopia, kucatshangwa ukuthi ungowohlobo olwalungaba yilungu lokuqala lomkhaya wamaHomo. Lokhu bekuyokwenza kube ukhokho ojwayelekile wabantu banamuhla - i-Homo sapiens - nezihlobo zabo eziphelile ezihlanganisa i-Homo habilis, i-Homo erectus namaNeanderthal. Ithambo lomhlathi elingaphansi elifakwe amatshe, eliboniswe ngenhla namazinyo asesemnkantsheni, latholakala eLedi-Geraru e-Ethiopia. Ososayensi bathi le nhlobo yezinsalela, eyaziwa ngokuthi i-LD 350-1, ibonakala ingumuntu kodwa futhi inezici zokuqala ezibonisa ukuthi indala kunezinye izinsalela zezinsalela zomndeni wakwaHomo. Abacwaningi abaye bakha kabusha umhlathi womunye ukhokho wasendulo womuntu nge-computer bathi leli thambo lembali lifana nalokho ababekulindele kulo khokho ofanayo. Eminyakeni eyizigidi ezingama-55 edlule - ama-primate okuqala aqalile ukuvela. Eminyakeni eyizigidi ezingu-15 eyedlule - amaHominidae izinkawu ezinkulu asuka kokhokho be-gibbon. Eminyakeni eyizigidi ezingu-8 edlule - ama-gorilla okuqala ayavela. Kamuva, uhlu lozalo lwama-chimpanzee nolwabantu lwahlukana. Eminyakeni eyizigidi ezingu-5,5 edlule - i-Ardipithecus, umuntu wokuqala wabelana ngezici noshimpanzi nama-gorilla. Eminyakeni eyizigidi ezine edlule - kwavela ama-Australopithecine. Ayengenawo ubuchopho obukhulu kunobuka-chimpanzee. Eminyakeni eyizigidi ezi-2.8 edlule - i-LD 350-1 yavela futhi kungenzeka ukuthi ingeyokuqala yomndeni wakwa-Homo. Eminyakeni eyizigidi ezingu-2,7 edlule - iParanthropus, yayihlala ehlathini futhi inemihlathi emikhulu yokuhlafuna. Eminyakeni eyizigidi ezingu-2.3 eyedlule - kucatshangwa ukuthi iHomo habalis yaqala ukuvela e-Afrika. Eminyakeni eyizigidi ezingu-1.8 edlule - iHomo ergaster iqala ukuvela emlandweni wezinsalela. Eminyakeni eyizigidi ezingu-1.6 edlule - izimbazo zesandla zaba yinto yokuqala enkulu kwezobuchwepheshe. Eminyakeni engu-800 000 edlule - Abantu bokuqala babelawula umlilo futhi benza iziko. Usayizi wobuchopho ukhula ngokushesha. Eminyakeni engu-400 000 edlule - amaNeanderthal aqala ukuvela futhi asakazeka kulo lonke elaseYurophu nase-Asia. Eminyakeni engu-200 000 edlule - i-Homo sapiens -  <response>: I-Jawbone - eyaziwa ngokuthi i-LD 350-1 - yatholakala esifundeni sase-Afar e-Ethiopia. Kungenzeka ukuthi leli thuna lalingelelelungu lokuqala lomndeni wakwaHomo. Kusho ukuthi umndeni wakwaHomo wavela eminyakeni engu-400 000 ngaphambili kunalokho obekucatshangwa. Ososayensi bacabanga ukuthi lingase limelele ukhokho ofanayo wazo zonke izinhlobo zabantu. Umhlathi wabelana ngezici nezinye izinsalela zeHomo kodwa futhi ungowokuqala. Ukutholakala kwalo kuye kwasiza ekuvaleni igebe elikhulu emlandweni wezinsalela zokuziphendukela kwethu. Ososayensi bathi kungasinikeza izinkomba ezintsha zokuthi izinhlobo zethu zavela kanjani.
