Isidalwa se-humanoid sohlobo olulodwa asiguquki sibe olunye uhlobo ngesikhathi sokuphila. Kepha umbuzo wokuthi kungani izinkawu zingaguquki zibe ngabantu uyajabulisa ngoba kusiza ukucabanga ngempilo, ukuziphendukela kwemvelo nokuthi kusho ukuthini ukuba ngumuntu.
Imvelo ibeka imingcele
Yize kunezinhlobo ezejwayelekile nezinhlobonhlobo zezinhlobo ezahlukahlukene, umuntu omdala ovela ohlotsheni olulodwa imvamisa akazalanisi nomuntu omdala ovela kolunye uhlobo (yize lokhu kungeqiniso kangako ezitshalweni, futhi kunokunye okuqaphelekayo kwezilwane).
Ngamanye amagama, ama-cockatoos wezinsizwa anombala ompunga akhiqizwa ngamabili ama-cockatoos avuthiwe kunamaMajor Mitchell.
Okufanayo kusebenza nakwezinye izinhlobo zezinto eziphilayo, ezingabonakali kangako kithina. Kunezinhlobo eziningi zezimpukane zezithelo, izimpukane zezithelo (izimpukane ezincane kakhulu ezikhangwa yizithelo ezibolayo, ikakhulukazi ubhanana) ezifana ngokufana.
Kepha abesilisa nabesifazane bezinhlobo ezahlukahlukene zeDrosophila abazivezi izimpukane ezintsha.
Izinhlobo azishintshi kakhulu, kepha ziyashintsha, kwesinye isikhathi isikhathi esifushane (ngokwesibonelo, uma kuphendulwa ukuguquguquka kwesimo sezulu). Lokhu kuphakamisa umbuzo othakazelisa kakhulu wokuthi izinhlobo ziguquka kanjani nokuthi izinhlobo ezintsha zivela kanjani.
Umbono kaDarwin. Ngabe siyizihlobo ezinezinkawu noma cha
Eminyakeni engaba ngu-150 edlule, uCharles Darwin wanikeza incazelo egculisayo kuyi-The Origin of Species. Umsebenzi wakhe wawugxekwa ngaleso sikhathi, ngokwengxenye ngoba imibono yakhe yayingaqondakali kahle. Isibonelo, abanye abantu babecabanga ukuthi uDarwin uphakamisa ukuthi ngokuhamba kwesikhathi, izinkawu ziphenduka zibe ngabantu.
Indaba ithi ngesikhathi kuxoxwa esidlangalaleni esidlangalaleni okwenzeka ezinyangeni ezimbalwa ngemuva kokushicilelwa kweThe Origin of Species, uMbhishobhi wase-Oxford uSamuel Wilberforce wabuza uThomas Huxley, umngani kaDarwin, "Ngabe umkhulu wakhe noma ugogo wakhe wayeyinkawu?"
Lo mbuzo uhlanekezela umbono kaDarwin: izinkawu aziphenduki zibe ngabantu, kepha kunalokho abantu nezinkawu banokhokho ofanayo, ngakho-ke kunokufana okuthile phakathi kwethu.
Sihluke kanjani kuzimfene? Ukuhlaziywa kwezakhi zofuzo eziphethe imininingwane esenza sibe yilokho esiyikho kukhombisa ukuthi izimfene, ama-bonobos nabantu bahlanganyela izakhi zofuzo ezifanayo.
Eqinisweni, ama-bonobos nezimfene yizihlobo eziseduze zabantu: okhokho babantu bahlukana nokhokho bezimfene cishe eminyakeni eyizigidi ezinhlanu kuya kweziyisikhombisa edlule. AmaBonobos nezimfene baba izinhlobo ezimbili ezihlukene muva nje cishe eminyakeni eyizigidi ezimbili edlule.
Siyafana, futhi abanye abantu bathi lokhu kufanagana kwanele ukuthi izimfene zibe namalungelo afanayo nawabantu. Kepha, kunjalo, sehluke kakhulu, futhi umehluko osobala kakhulu yilokho okungavamile ukubonwa njengokuphilayo kuyisiko.
