Kungani abantu abancane besadinga usizo lwethu

Uma inani lezinhlobo zezilwane lehla, kubonakala kunengqondo ukucabanga ukuthi ukuthi izinhlobo zizosondela ekuqothulweni. Ngenani labantu abambalwa, phela, izinkinga ezivela ngokwemvelo phakathi kwezinhlobo zezilwane noma imvelo kufanele zibe nomthelela omkhulu. 

Isibonelo, uma une-$100 futhi uchithe uhhafu wayo, usazoba no-$50 osele—inani elilinganiselwe lemali yokusebenzisa. Uma uqala ngo-$10, ngakolunye uhlangothi, ukusebenzisa uhhafu wemali yakho kukushiya ucishe wephuke. 

Kodwa kuthiwani uma le logic inephutha? Iqembu la Concordia ososayensi muva nje ishicilele iphepha ngaphakathi Izicelo zokuziphendukela kwemvelo ukusikisela lokho nje: ukuthi isibalo esincane sabantu sinethuba elingcono lokusinda kunalokho esikucabangayo. 

Ingxabano yezibalo zabantu abancane 

Kusetshenziswa ulwazi oluqoqwe kusuka emaphepheni adlule asukela ngo-1980, ucwaningo lwe-Concordia luqhathanisa osayizi besibalo nenani lokuhlukahluka kofuzo elingadluliswa lisuka kumzali liye kubantwana. Iphinde ihlole ukuze ibone ukuthi inani                                  inanoma yimuphi umthelela emandleni ezakhamuzi okukhethwa kwemvelo. 

Lokhu kuqhathanisa kusetshenziswe ezinhlobonhlobo zezinhlobo, ngethemba lokuthi okutholwe ocwaningweni kuzofakazelwa kumhlaba wonke—okubonakala kunjalo. Amandla okukhetha kanye namandla okuzivumelanisa nezakhi zofuzo ahlala engaguquki kubo bonke osayizi bantu. Lo mphumela usho ukuthi lezo zinkinga azinawo umthelela okhethekile ekwehleni kwezibalo zabantu. 

Izinkinga ngempikiswano 

Kungenzeka ukuthi imiphumela etholwe ucwaningo lwe-Concordia yayingenxa yokuthile okungekona amandla ezibalo zabantu ezinciphayo. Amanye amathuba ahlanganisa amaphutha endlela, ukunemba ezilinganisweni, isikhathi socwaningo esinganele kanye nokuqagela ngokweqile. 

Okokuqala, ukufunda ngezinhlobonhlobo ezinjalo zezinto eziphilayo kungenza kube nzima ukuhlonza kahle iphethini eyodwa ecacile. Harmony Dalgleish, uprofesa wesayensi yezinto eziphilayo e-College of William and Mary, uthi ngoba abacwaningi “bangena kuzo zonke lezi zinhlobo zezinhlobo zezilwane ezinezici ezihlukahlukene zomlando wempilo, angiqiniseki ukuthi ungalindela nokuthola iphethini.” 

Okwesibili, ukuziphendukela kwemvelo kuthatha isikhathi eside ngendlela emangalisayo. Uprofesa webhayoloji UHelen Murphy uyachaza: “Lawa cishe, ngezinga elithile, ngezinga lokuziphendukela kwemvelo okungenani, abantu abahlukene abasanda kuhlukana, ngakho lezi izinyoni eziphila isikhathi eside okuthi, ngisho noma kwakuyiminyaka engu-20 lapho indawo yazo yokuhlala yahlukana phakathi, kusazoba nethoni izakhi zofuzo - buya eminyakeni engu-300 futhi ubone ukuthi utholani.” 

Ngamafuphi: isibalo sabantu ngeke siphendule ngokushintsha usayizi ngaphandle uma kudlule izizukulwane eziningi. Iphepha le-Concordia, ngeshwa, lalingenalo ulwazi lwesikhathi eside kangako.
