<prompt> Pfupisa nyaya yacho: CNN Nekuwanikwa kwedehenya, rakabva mumatombo emuhuro mune imwe nzvimbo iri kure yeEthiopia, mumwe mudzidzi wepaArizona State University angave akachinja kunzwisisa kwatinoita madzitateguru edu ekare. Chimwe chikamu cheshaya yepazasi ndicho chiratidzo chekare zvikurusa chinozivikanwa chezvicherwa zveboka reHomo, iro vanhu vemazuva ano vanobva mariri, maererano nokudzidza kwakabudiswa neChitatu mumagazini inonzi Science. Pfupa romuhuro racho rakanyorwa kuti rakanyorwa makore 2.8 miriyoni akapfuura - izvo zvinotangira zvisaririra zvaizivikanwa kare zvorudzi rwaHomo namakore anenge 400 000 akapfuura, maererano neArizona State University. Chalachew Seyoum, mudzidzi akapedza kudzidza anobva kuEthiopia, akawana zvisaririra izvi - rutivi rworuboshwe rwemhino yepasi ine mazino mashanu - paaiita basa rokuongorora munzvimbo yeAfar kumabvazuva kweEthiopia muna 2013. Kutaura chokwadi, yakanga iri nguva inofadza, Seyoum akadaro, maererano neshoko renhau kubva kuyunivhesiti. Ndaiva noruzivo rwakanaka mukunzvera nzvimbo uye ndaiziva kwaigona kuva nemarara. Ndakakwira pachikomo chiduku ndokuwana uyu muenzaniso chaipo pamucheto pegomo. Zera rechinhu ichi chakawanikwa rinoreva kuti chinogona kubatsira kuzadza mukaha unokosha muzivo yedu. Fossil yakawanikwa nomuredzi wehove ingaratidza rudzi rutsva rwomunhu wekare. Zvinorevawo kuti rudzi rwaHomo rwunogona kuva rwakashanduka-shanduka makore anosvika hafu yemiriyoni apfuura pane zvaifungidzirwa kare. Vatsvakurudzi vakambowana zvisaririra zvemafosili zvaiva nemakore 3 miriyoni kana kupfuura, zvakadai seLucy, zvisaririra zvakakurumbira zvemakore 3.2 miriyoni zvemarudzi eAustralopithecus afarensis. Zvinhu zvacho zvakawanikwa muna 1974 kwete kure nenzvimbo yakawanikwa zvinhu zvitsva. Masayendisiti akawanawo zvisaririra zvemakore mamiriyoni 2,3 ezera uye zviduku, izvo zviri muchizvarwa cheHomo uye zviri pedyo zvikuru nevanhu vemazuva ano. Asi kusvika pari zvino pane zvisaririra zvishomanana zvemakore 700 000 ari pakati pezvi - nguva inokosha mukushanduka-shanduka kubva kuvanhu vakaita saLucy kuenda kurudzi rwevanhu. William H. Kimbel akati, Kukosha kwechiratidzo chacho ndechokuti chinowedzera mashoko pamusoro penguva iri munhoroondo yemadzitateguru edu yatinongoziva zvishomanana nezvayo.  <response>: Mhanza yacho yakawanwa munharaunda yeAfar yeEthiopia, kwete kure nenzvimbo yakawanikwa Lucy.
