<prompt> Fingqa isihloko: Ucwaningo olusha lusikisela ukuthi kungenzeka ukuthi okhokho babantu bokuqala baqala ukujikijela imikhonto eyayibenza bakwazi ukuzingela eminyakeni engaba yizigidi ezimbili edlule. Ososayensi baye bathola ukuthi amathambo ezinhlobo zokuqala zabantu ashintsha ukuze azinike amandla okuphonsa njengabantu banamuhla. Ukuhlola izinsalela ze - Homo erectus, ukhokho wesintu osuphelile, kubonisa ukuthi amahlombe namathambo ayo ekhola kwakuyivumela ukuba iphonse izinduku ngokunembile nangamandla. Skrolela phansi ukuze ubone ividiyo. Ukuhlola izinsalela ze - Homo erectus, ukhokho wesintu osuphelile, kubonisa ukuthi amahlombe namathambo ayo ekhola kwakuyivumela ukuba iphonse izinduku ngokunembile nangamandla. Amathambo ashiwo ngenhla e-Homo erectus avuselelwa ngezinsalela ezazisetshenziswa abacwaningi esifundweni sabo. Lokhu kwakuyokwenza i-Homo erectus ikwazi ukuba umzingeli onekhono, okwazi ukuphonsa izikhali ezinjengemikhonto namatshe ekuzingeleni okungenzeka. UDkt. Neil Roach, isazi sesayensi yezinhlobo zabantu eGeorge Washington University eWashington, wathi: Inhlanganisela yamahlombe aphenduka kancane, afana nawomuntu anebhande eliphakeme, elishukumisayo nokugoba okuncane kwe-humeral, kusekela iHomo erectus njenge-hominin yokuqala eyaziwayo ephethe isakhiwo esiphelele se-anatomical esihambisana nokuphosa okunekhono. 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 - Izembe lesandla liba ubuchwepheshe bokuqala obukhulu...  <response>: Ososayensi baqhathanisa amahlombe e-Homo erectus nabantu banamuhla. Abacwaningi baseGeorge Washington University balinganise ikhono lokuphosa labantu beDaasanach eKenya nase-Ethiopia. Abantu baseDaasanach babekwazi ukujikijela izinduku ngesivinini esingamakhilomitha angu-80 ngehora ngaphezu kwamamitha angu-100. Ososayensi bathola ukuthi iHomo erectus yayingaba namakhono afanayo. I-Homo erectus yayingafanisa abasubathi banamuhla ngekhono labo lokuphosa.
