<prompt> Fingqa isihloko: Abantu abaningi nabo balangazelela ukubukeka njengabadayisi abakhulu, kodwa kubonakala sengathi okhokho bethu bokuqala kungenzeka ngokwemvelo babenamathanga afana nawomfelokazi nemilenze emincane. Ososayensi abahlolisisa ithambo lomgogodla nelendololwane elineminyaka eyizigidi ezingu - 1,9 ubudala baye bathola ukuthi uhlobo oluthile lwabantu bokuqala manje osucishe lwaphela lwalunemizimba ehluke kakhulu kweyethu. Kucatshangwa ukuthi leli thuna lingelase-Homo rudolfensis noma i-Homo habilis, izinhlobo ezimbili zokhokho bomuntu ezavela e-Afrika. I-femur ne-pelvis eneminyaka eyizigidi ezingu - 1,9 ubudala ngenhla kucatshangwa ukuthi ingekaHomo habilis noma iHomo rudolfensis. Nakuba ososayensi sekuyisikhathi eside befunda ukwakheka kobuchopho nobuso balezi zinhlobo, manje sebeqala ukubheka imizimba yazo. Ngokokucwaninga okwaholwa izazi zezinhlobo zabantu e-University of Missouri, lezi zinhlobo zokuqala zikaHomo zazinemithambo emincane kakhulu emincane namathambo ezinqeni uma kuqhathaniswa nezinhlobo zethu, uHomo sapien nezinye izinhlobo zabantu eziqothuliwe uHomo erectus. 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 ezingu-2,7 edlule - iParanthropus, yayihlala ehlathini futhi inemihlathi emikhulu yokuhlafuna. Eminyakeni eyizigidi ezi-2.8 edlule - Amalungu okuqala omndeni wakwaHomo abonakala e-Afrika njengoba kuboniswa yi-LD 350-1 fossil etholakala e-Ethiopia. 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-pelvis ne-femur eziyimbudumbudu ezivela kubantu bokuqala ezitholakala eRif Valley, eKenya. Ososayensi bakholelwa ukuthi kungokwalabo Homo rudolfensis noma Homo habilis. Umlenze wesibeletho nowesibeletho sezinsalela kuncane kakhulu kunalezo zabantu banamuhla. Lokhu kusikisela ukuthi okhokho bethu babenemilenze namathanga amancane kune-Homo sapiens. Imivubukulo ibonisa ukuthi abantu bokuqala babenemilo ehlukahlukene yomzimba kanye nogebhezi.
