Imuphi umnikazi wenja ongasazi isimo: Kufanele uhambe ngokushesha futhi ukhiye wemoto ngeke utholakale futhi. Lapho umyalo othi "sesha" unikezwa, inja igijima ngokujabula, kodwa ngeshwa ayisibonisi ukuthi ukhiye ukuphi. Kunalokho, uthola ithoyizi lakhe. Kuhle! Ingabe inja izicabangela yona kuphela futhi ayifuni ukusisiza nhlobo?
"Ngokuphambene nalokho! Izinja zizimisele kakhulu ukusisiza thina bantu. Abaceli nomvuzo ngakho. Kufanele sibacacisele ukuthi sifunani kubo,” kusho isazi sezinto eziphilayo nososayensi uDkt Juliane Brewer wase-University of Jena.
Ekhuthazwa ngisho ngaphandle kokuqeqeshwa
Impela - ungaziqeqesha izinja ukuthi zibheke futhi zikhombe entweni ethile. Nokho, uJulianne Bräuer nethimba lakhe babefuna ukuthola ukuthi ingabe izinja ziyazi yini lapho sidinga usizo ngaphandle kokuqeqeshwa, noma zisinika lokhu ngokungenabugovu, futhi kungaphansi kwaziphi izimo lokhu.
Ukuze bathole lokhu, ososayensi bameme abangaqeqeshiwe abazohlolwa abanemilenze emine ocwaningweni eMax Planck Institute for Evolutionary Anthropology eLeipzig. Ezivivinyweni, abacwaningi babeke ukhiye ekamelweni elingemuva komnyango we-Plexiglas ongavulwa ngomshini. Ukhiye wawubonakala ezinjeni.
Izinja zithanda ukubambisana
Kuvele ukuthi izinja zazizimisele kakhulu ukusiza umuntu. Kodwa-ke, babencike emikhondweni yokuthi bangakwenza kanjani lokhu: uma umuntu ehlala futhi efunda iphephandaba, nenja yayingasenandaba nokhiye. Nokho, uma umuntu ebonise isithakazelo esicabheni nakukhiye, izinja zathola indlela yokuvula iswishi esicabheni. Lokhu kusebenza kuphela uma abantu beziphatha ngokwemvelo ngangokunokwenzeka.
Izinja zabonisa lokhu kuziphatha okuwusizo izikhathi eziningana, ngisho nangaphandle kokuthola umvuzo ngakho - kungaba ngendlela yokudla noma uhlobo lokudumisa. Ososayensi baphetha ngemiphumela yokuhlolwa ukuthi izinja zifuna ukusiza abantu. Kodwa uzokuqonda kuphela uma sinikeza ulwazi olufanele.
Kodwa kungani izinja ziwusizo kangaka? “Kungenzeka ukuthi ngesikhathi sokufuywa, ukuziphatha ngokubambisana kwaba usizo, futhi kwakhethwa izinja eziwusizo,” kusho uDkt. Brewer.
Ngendlela, abangani abanemilenze emine abanegama elithi "bazojabulisa", okungukuthi isidingo sokujabulisa abantu "babo", bayizinja zomndeni ezithandwa kakhulu namuhla noma zivame ukusetshenziswa njengezinja zokuhlenga nokusiza. Banaka kakhulu abantu “babo” futhi bebengenza zonke izifiso zabo – ukube bebazi ukuthi kanjani.
