<prompt> Fingqa isihloko: Cishe kungenye yezinto eziyinqaba kakhulu empilweni yomuntu - ukuthi abesifazane abaneminyaka ethile ubudala balahlekelwa ikhono lokuzala. Manje ososayensi baye bathola ukuthi ama-killer whale - uhlobo oluhlukaniswe nabantu ngeminyaka ecishe ibe yizigidi ezingu-94 yokuziphendukela kwemvelo - nawo ahlaselwa ukuyeka ukuya esikhathini futhi lokhu kungase kunikeze izinkomba zokuthi kungani yaziphendukela kwasekuqaleni. Kukhona olunye uhlobo olulodwa kuphela emvelweni olwaziwa ngokuba nesikhathi sokunqamuka kokuya esikhathini - imikhomo emfushane - nakuba kuye kwabonwa kwezinye izilwane ezincane ezifuywayo. Imikhomo emikhulu yensikazi ivame ukuhola njengalena engenhla lapho imindeni ifuna ukudla. Sekuyisikhathi eside izazi zezinto eziphilayo zixakwe ukuvela kwalesi sici esinciphisa ikhono lohlobo oluthile lokuzala, futhi kunemibono eminingana yokuthi kungani savela kubantu. Manje iqembu labacwaningi abavela e-University of Exeter nase-University of York kungenzeka ukuthi seliyitholile imbangela yokunqamuka kokuya esikhathini - okungenani emalulwaneni. Kwenzeka kuwo wonke owesifazane ofinyelela eminyakeni ethile, kodwa embusweni wezilwane, ukuyeka ukuya esikhathini kuwuphawu olungavamile. Abantu bangaphila isikhathi eside ngemva kokuba sebengasakwazi ukuzala, kodwa izilwane eziningi zivame ukuhlala zizala zize zife. Izinhlobo ezimbalwa zezilwane ezincelisayo, njengezinkawu ze-rhesus, ama-orangutan kanye nama-chimpanzee nazo ziyaziwa ukuthi zihlushwa ukuyeka ukuya esikhathini kanti futhi kubikwe nasezindloveni nakuma-pilot whale anezimpiko ezimfushane. Amagundane okuhlola, ama-opossum aboshwe kanye nama-budgerigars nawo aye abonwa ephila isikhathi sokuya esikhathini. Nokho, imikhomo emfushane ebizwa ngokuthi ama-pilot whale kanye nemikhomo ebizwa ngokuthi ama-killer whale yiyo yodwa eye yabonwa iphila isikhathi eside ngemva kokuba seyilahlekelwe amandla okuzala. Baye bathola ukuthi kukhulula abesifazane abadala, abanolwazi ukuba bahole imikhaya yabo ekufuneni ukudla futhi ngaleyondlela kuthuthukise ikhono lalo lonke iqembu lokusinda. Lokhu okutholakele manje kungase kusize ekuchazeni ukuthi kungani ukuyeka ukuya esikhathini kwaqala kubantu - kwakuvumela abesifazane asebekhulile ukuba badlulisele ulwazi lwabo futhi basize ekunakekeleni amalungu amasha omkhaya. UProfesa...  <response>: Ama-killer whale angenye yezilwane ezimbalwa eziya esikhathini. Ama-short-finned pilot whale nama-killer whale yiwona wodwa ama-whale asendle okwaziwa ukuthi abesifazane bawo balahlekelwa ikhono lokuzala njengoba bekhula, njengabantu. Ama-killer whale adlula esikhathini sokuya esikhathini esilinganisweni seminyaka engu-35 ubudala. Izinsikazi esezikwazi ukuzala zivame ukuhola amaqembu lapho zizozingela i-salmon. Cishe zihola kakhulu ngezikhathi zokuntuleka kwezilwane lapho kunzima ukuthola ama-salmon. Ososayensi baseNyuvesi yase-Exeter bathi abesifazane abadala badlulisela ulwazi lwabo nokuhlangenwe nakho kwabo ukuze kuzuze wonke umndeni wabo. Kungase kusize ekuchazeni ukuthi kungani ukuyeka ukuya esikhathini kwaqala kwabesifazane asebekhulile.
