Pfupisa nyaya yacho:  Kana toreva nezvokugadzira zvinhu zvokuzviitira woga zvinoratidza kuti varume vane unyanzvi kupfuura vakadzi. Asi kutsvakurudza kutsva kwakaratidza kuti mhuka dzechikadzi dzingava dziri nani pakushandisa zvishandiso - zvikurukuru pakati petsoko. Vanotsvakurudza vakaona kuti tsoko hadzi dzinowanzoshandisa maturusi aya kuti dziwane zvokudya nepo dzorume dzichiwanzosarudza kubata mhuka nemaoko. Dzorera pasi kuti uone vhidhiyo. Nyanzvi dzinoongorora mhuka dzomusango paIowa State University dzakarekodha kuvhima 300 kwakaitwa nemachimpanzi muFongoli, Senegal, uye dzakawana kuti machimpanzi echikadzi aishandisa zvishandiso kuti abate mhuka dzawo mu60 muzana yezvakaonekwa. Iyi shimpanzi yechikadzi yakabvisa tsvimbo yemashizha uye inoishandisa kubudisa mwana mudondo kubva mudanda remuti risina chinhu. Nepo zvakawanwa izvi zvingaita kuti vamwe vaongororezve maonero avanoita vakomana nevasikana, kutsvakurudza uku kungapawo mashoko anonakidza pamusoro pokuti vanhu vakatanga sei kudzidza kushandisa zvombo kuti vavhime. Zvinoratidza kuti zvichida vakadzi vokutanga ndivo vakatanga kugadzira zvishandiso zviri nyore zvaivabatsira kubata mhuka. Kwave kuchizivikanwa kuti shimpanzi dzinoshandisa zvishandiso sezvinoita vanhu kwamakore anopfuura 50. Muna 1960, Jane Goodall akaona shimpanzi mbiri dzichishandisa matavi kuti dzibate hove dzemakonye ari pasi. Aka kaiva kokutanga kuti mhuka ipi zvayo isiri vanhu ionekwe ichigadzira chokushandisa uye ichishandisa nokuda kwechinangwa chakati. Gare gare kwakawanwa kuti machimpanzi eGombe anoshandisa matavi, mashizha namatombo munzira pfumbamwe dzakasiyana-siyana kuti adye, anwe, azvichenese amene, asvike zvimwe zvinhu uye kugadzira zvombo. Munharaunda dziri kunze kweGombe National Park, vanhu vanogadzira maturusi akasiyana-siyana. Chimpanzi dzinogadzira siponji nokukuya mashizha ndokudzinyudza mumadhamu emvura kuitira kuti dzikwanise kuzvishandisa semidziyo yokunwa. Dzakacherechedzwa dzichishandisa matanda nematombo kupwanya michero nemakwati. Idzo dzakura dzimwe nguva dzinokanda matombo netsvimbo sezvombo zvokunyepedzera kuti dzityisidzire vadzivisi vadzo. Ongororo iyi yakati shimpanzi dzinoshandisa mashizha eAlchornea hirtella kuti dzivhime masvosve ane utsinye nenzira chaiyo. Zvinofungidzirwa kuti mufambiro wacho unopfuudzwa kubva kuchizvarwa chimwe kuenda kune chinotevera uye unodzidzwa nemachimpanzi maduku. Kunyora...
Vaongorori vakanyora nezvemachimpanzi dzaivhima nematurusi kuFongoli kuSenegal. Kushandiswa kwechombo kwakacherechedzwa pazviitiko 300 uye 60% yakanga iri yevakadzi. Chimpanzi dzakarume dzaiwanzovhima asi dzaiwanzotora mhuka nemaoko. Zvakawanikwa izvi zvinogona kutibatsira kuziva kuti vanhu vakatanga sei kudzidza kushandisa maturusi.
