Mhlawumbe, ayikho inhlobonhlobo yezinja ehlanganiswe nenani elikhulu kangaka lezinganekwane, njengezinja ezingenalutho, okubukeka njalo kubangela ukumangala ezindaweni ezungezile futhi ngezinye izikhathi ngisho nokwesaba. Mayelana nemvelaphi yabo, ososayensi abazi kangako, okuyinto enye isizathu sokukhathazeka ezweni labasebenzi bezinja. Izinja eziphukile zaziziwa kubantu abahlala emazwenikazi ahlukene. Okuphela kwendawo yonke, i-Australia kanye namazwe anesimo sezulu esishisayo kakhulu asele ngaphandle.
Umlando wemvelaphi
Kuze kube manje, lokhu okulandelayo kuhlala kuyimfihlakalo emlandweni: ngabe ngabe kunezinhlobo zezinja zezinja emazweni ahlukene ngenxa yezinguquko ezifanayo noma zihlobo ezikude. Mhlawumbe, ezikhathini zangaphambi kwesikhathi lezizinja zinehambo oluhamba phambili. Isibonelo, ukuya eMelika esuka e-Asia, noma ngokuphambene nalokho. Kodwa-ke, leli qiniso cishe akunakwenzeka ukusungula.
Izinja zokuqala, ezazingekho izinwele, zavela, ngokusho kwabacwaningi, e-Afrika endaweni yaseGorky yeBig Lake. Bangase balahlekelwe uboya babo ngenxa yezinga eliphezulu lokushisa elikhona kulezi zindawo. Ukushisa nokushisa kungabangela ukungabi nezinwele okuphelele (ezimweni ezingavamile, kwakukhona i-bristle encane ekhanda, iminwe kanye nomsila womsila), indawo yokuzikhukhumeza kwi-surface yonke yesikhumba, ngoba kuphela izinja ezingenalutho ngesikhathi sokushisa ukupholisa ungabambeli ulimi lwazo. Ngesinye isikhathi lezi zilwane azizinamazinyo noma aziguquki kusuka ebisikolweni kuya emdabu. Ngokuvamile kuthinta i-premolars. Ukungabikho kwezinwele kuyinto ebaluleke kakhulu.
Namuhla, izinja ezingenalutho ezazisinda emakhulwini amaningi eminyaka, zitholakala emhlabeni wonke ezindaweni eziningi ezingaphansi komhlaba. Bangatholakala
Imfuyo yezinja zezinja
Njengamanje, i-International Cynological Federation imemezele ngokusemthethweni izinhlobo eziningana, abameleli bayo abaphelele noma cishe bangenazo zonke izibopho zeboya. Ziyizinja zaseNtshonalanga zaseShayina, zasePeruvia, zaseMelika, kanye nenja ehlanzekile yaseMexico enezinhlobonhlobo zayo - i-mini ne-puff. Ngaphezu kwalokho, kunezinhlobo eziningana ezingakaze zibonwe yi-ICF: inja ehamba phambili yezinja ze-Incas, i-Antilles ne-Abyssinian, imboni yase-Argentina, i-Turkish Greyhound, i-Indian rampur nenja ye-elephant Afrika. Yiqiniso, zonke zingabhekwa ezinzalweni ezingavamile zezinja .
