Ingabe izinja zingalingisa ezinye izilwane nabantu?

Izazi ze-Ethology kuze kube muva nje zikuphika ngokuphelele ukuthi kungenzeka ukuthi izinja zingalingisa ezinye izilwane nabantu. Leli khono kwakucatshangwa ukuthi liyingqayizivele kubantu nasezinkawini (njengama-orangutan nezimfene). Kodwa ingabe kunjalo?

Ososayensi baqala ukungabaza ngalokhu.

Kuyaziwa ngokuqinisekile, isibonelo, ukuthi izinja "zitheleleke" ngemizwa yomunye nomunye neyomuntu. Ngakho-ke, ngokwesilinganiso, inja idinga cishe imizuzwana emi-2 ukuze "ibuke" isimo somzwelo somnikazi. Futhi uma ethukile, nenja izothuthumela. Uma ejabule, uzojabula. Futhi lokhu kungasiza futhi kuvimbe emfundweni nasekuqeqesheni. Kodwa kunoma yikuphi, abantu badinga ukuqaphela kahle isimo sabo somzwelo kanye nomthelela waso kumngane onemilenze emine.

Kodwa kuthiwani ngokuphindaphinda izenzo? Ingabe izinja ziyakwazi lokhu?

Kulokhu, abacwaningi bokuziphatha kwezinja abazwani ngazwi linye.

Ngokwesibonelo, ucwaningo olwanyatheliswa kuyi-Journal of the Royal Society of London luthi izinja ziyakwazi ukukopisha izenzo zomunye. Kunombono wokuthi ikhono elinjalo lathuthukiswa ohlelweni lokufuywa ekhaya.

Ukuhlola kuphinde kwabonisa ukuthi izinja ezidinga ukuxazulula umsebenzi othile (ngokwesibonelo, ukweqa uthango olumise okwe-V futhi zicoshe ithoyizi) zenze kangcono uma ngaphambili zazibone indlela abantu noma ezinye izinja eziwenza ngayo.

Nokho, abaningi basangabaza. UJohn Bredshaw (University of Bristol) ukholelwa ukuthi ucwaningo olwengeziwe luyadingeka ukuze kuphendulwe lo mbuzo ngokuqinisekile.

Nokho, ukulingisa kusetshenziswa ekuqeqesheni izinja. Ngokwesibonelo, ososayensi baseNyuvesi yaseBudapest, K. Fugazzi kanye no-A. Mikloshi, basungula indlela yokwenza “Yenza njengoba ngenza” esekelwe emiphumeleni yocwaningo. Le nqubo isekelwe ekulingiseni kwenja izenzo zomuntu futhi isetshenziselwa ukuqeqesha izinja ezisizayo ezintweni eziyinkimbinkimbi. Abathuthukisi be-methodology bakholelwa ukuthi into eyinhloko ukufundisa inja isimiso esithi "Phinda," futhi izobhekana ngokuphumelelayo nemisebenzi eminingi, iphinda izenzo zomuntu oyifundisayo.

Kunoma yikuphi, kusenemibuzo eminingi kunezimpendulo. Futhi kubaluleke kakhulu ukuqhubeka nocwaningo ukuze okungenani sisondele ekuqondeni umhlaba wangaphakathi wabangane bethu abakhulu.
