Yintoni labemi ngokwemigaqo eziphilayo? Izazinzulu ukunika loo inkcazelo: ke inani elithile labantu abahlala kwindawo enye, ukuba commonality yemfuza kunye nesakhono ukuze ukuzala.
Isakhiwo genetic abantu yeyona nto iphambili ukuba ihlanganise iintlobo abantu. Oku kuchaphazela kuphela sokudlala, kodwa lo mbutho yemveliso yokutya, kulwalamano intraspecific. Unako ukunika umzekelo. Izazinzulu isigqibo ukufumana oko ke abantu zohlobo olufanayo kwiimeko ezahlukeneyo. Le lokulinga lwaqhutywa elebhu. namaqembu ezimbini zinkumbi banikwa kwimigqomo ngaphaya. Enye ibe ngabantu abahlanu omnye - ikhulu. Ekuqaleni, uphuhliso waba twatse. Kwizikhongozelo bobabini banikwa loo mali efanayo ukutya. Xa inani elincinane izinambuzane baqhubeka ukuba baziphathe ngokuzola, baba ezinkulu, non-silwe. In a elikhulu - izinambuzane ebezisoloko nobunzima: i ukutya ngokwaneleyo, kwaye isithuba kakuhle. Aba bantu zincinane kakhulu ngobukhulu Xa kuthelekiswa izalamane wondleke kwaye nochuku kakhulu. Bakhawuleza wavuka phezu iphiko. Kodwa ukunqongophala kokutya kwakhokelela ekubeni iinkumbi zange nande, yaye abaninzi baqalisa ukuba buhlungu. Le experiment ibonisa ukuba inani nendlela liyaguquka kuxhomekeka kwiimeko zeendawo ezikuzo.
Empirically, kuye kwabonakala ukuba intlalo-ntle uhlobo ixhomekeke ngempumelelo ngayo lokuzalanisa lwenzeka kunye nenkqubo yophuhliso imimandla ezintsha. Le yinxalenye lweempawu ezimile kunye neguquguqukayo oluntu. Lokuqala - nithi, njengokuba inxenye eyahlukileyo zohlobo olufanayo nga ziyazala ngokwayo. Okwesibini - indlela labemi liyakwazi ukuba luthathe indawo enkulu, kunye nabameli balo - ukuziqhelanisa utshintsho lobume.
Yintoni abantu xa uthathela ingqalelo okusingqongileyo ngayo? Le ngcamango ibonakala ngokuyintloko njengomba utshintsho bume. Leyo yenye labemi a iintlobo ezikhokelela kumsebenzi ebalulekileyo kwindawo ethile, nempembelelo esebenzayo kwi inguqu kwiimeko zokuphila nje ngohlobo lwayo, kodwa abanye. Umzekelo isekhona iinkumbi efanayo. Xa abantu bayo kwandisa ukuya ubungakanani enkulu kakhulu, iba phezu iphiko iqala bafuduka, esidla yonke into esendleleni yayo. Ngenxa yoko, ukukhula kwamanani kweentlobo omnye kukhokelela ekutshatyalalisweni abanye.
Yintoni na labemi umntu eziphilayo? Lo ngumbuzo umdla kakhulu. Uluntu ithatha up uninzi kumphezulu-langa. Homo sapiens yenye yezo ntlobo ukuba kakhulu ngenkuthalo ukutshintsha engqongileyo ubomi babo. Inani labantu kakhulu likhula kakhulu ngokukhawuleza. Kwaye kukho uloyiko lokuba indalo iza kuqalisa ukulawula ukwanda yethu. Kuye iindlela ezininzi ezichaphazela uluntu. Oku ngu mda kwezibonelelo ukutya, amanzi acocekileyo, izifo ezosulelayo ezinokubangela zande kakhulu. Oko kukuthi, iindlela zendalo. Ukongeza, kukho izinto ezichaphazela urhulumente ngokweemvakalelo nangokwasengqondweni: ndlongo eyonyukileyo kunye nokhuphiswano kwizibonelelo.
