Zininzi iithiyori ezithetha ngohlobo lwe zobulumko ukuba izinja zinazo, nangona izimvo zokuba i-IQ yazo inokulinganiswa yahlukile rhoqo. Kule minyaka imbalwa idlulileyo kuye kwakho izifundo ezininzi ezijongana nale ngxaki, kwaye eziye zadala inani elikhulu leemvavanyo ukubala ngokwesayensi inqanaba lokuqiqa kwezi zilwanyana.
Phakathi kwabo, le yenziwa ngoFebruwari walo nyaka ngu Isikolo soShishino saseLondonNgokusebenzisana neYunivesithi yase-Edinburgh. Iqela lezenzululwazi lenze uvavanyo lwe-canine test prototype apho bavavanya khona iikopi ezingama-68 zeBorder Collies, ezithathwa njengolona hlobo lubalaseleyo. Olu vavanyo lubandakanya iimvavanyo apho izinja kwafuneka zahlule phakathi kwexabiso lokutya ezahlukeneyo okanye ukufikelela kwiindawo zokutya ezifihlwe ngasemva kwemiqobo eyahlukeneyo.
Izigqibo zesifundo, ezipapashwe kwijenali Intelligence, zatsho ukuba izinja ezigqibe ukuvavanya ngokukhawuleza (nganye yayineyure njengomda wexesha), zenze ngokuchanekileyo ngakumbi. Abaphandi bafumanise ukuba abo baqhube ngcono kuvavanyo olunye bahlala bezosebenza ngakumbi kwabanye. Ngale ndlela, babonisa ukuba ubukrelekrele be-canine busebenza kwifayile ye- ngokufana nomntu, ukwahlula ngokugqibeleleyo iintlobo ezahlukeneyo zemisebenzi yokuqonda.
Injongo yolu phando kukuqonda ubudlelwane obukhoyo phakathi zobulumko kunye nempilo, into enokunceda kakhulu ekunyangeni izifo ezinje ngesifo sengqondo esixhalabisayo. Njengoko uRosalind Arden weSikolo soShishino saseLondon esichaza: 'Izinja zezinye zezilwanyana ezimbalwa ezizala uninzi lweempawu eziphambili Isifo sengqondo esiyingozi, Ukuqonda ubuchule babo bokuqonda kunokuba luncedo ekusincedeni siqonde oonobangela boku kuphazamiseka ebantwini kwaye mhlawumbi nonyango lwesilingo.
