Izinhlobo eziningi zezinja zasendulo zafunwa yiqembu labaososayensi baseSweden eliholwa uPetra Savolainen, uprofesa woMnyango weZoology e-Stockholm Royal Institute of Technology.
Izinyathelo zokuqala zokutadisha
Ukuze uthole ukwaziswa okuthembekile ngo-2004, i-DNA ye-mitochondrial (ifa elivela ku-feminine) yezinja zanamuhla kanye nobaba babo bezilwane zasendle zaqhathaniswa. Ngenxa yemininingwane etholakalayo, ukufana okukhulu nezimpisi kwisakhiwo se-DNA kwavezwa ezinyangeni eziyi-14 zenja.
Imikhumbi yasendulo ishiya ekuthuthukisweni kusuka okhokho babo iminyaka eyizinkulungwane eziningana. Ukuthola okudala kunazo zonke zokuvubukulwa kwezinja ezifuywayo sekuyiminyaka engaba ngu-15 000 ubudala. Kodwa-ke, ezinye izazi zezinto eziphilayo zikholelwa ukuthi izinhlobo zasendulo zezinja zasendulo zihlukaniswe nempisi ekuqaleni.
Usosayensi uRobert Wayne ukholelwa ukuthi ukubonakala kwenja efuywayo kwenzeka esikhathini esidlule kunokubeka impilo yokuphila yabantu (eminyakeni engaba ngu-10 000 kuya ku-14 000 edlule). Esikhathini esidlule, ososayensi bakholelwa ukuthi abantu bokuqala abazange baqale izilwane ezifuywayo. Kodwa-ke, ngokusho kukaRobert Wayne, izinja zokuqala zavela eminyakeni eyi-100 000 edlule noma okuningi ngaphambili.
Ososayensi abaningi bakholelwa ukuthi izinja zasendulo zavela e-East Asia. Esikhathini sokucwaninga, kwakukhona lapho okutholakala khona ukuhlukana okukhulu kwezakhi zofuzo, okubonakala ngokuphansi kunezinye izifunda namazwekazi.
Izinja zasendulo kakhulu
- Akita Inu (Japan)
- I-Alaskan Malamute (i-Alaska)
- I-Afghan Greyhound (e-Afghanistan)
- I-Basenji (Congo)
- I-Lhasa Futhi (i-Tibet)
- I-Pikenes (China)
- I-Saluki (ICrescent Ecebile eMpumalanga Ephakathi)
- I-Samoyed Dog (eSiberia, eRussia)
- Shiba Inu (Japan)
- I-Husky yaseSiberia (iSiberia, iRussia)
- I-Tibetan Terrier (i-Tibet)
- I-Chow Chow (China)
- I-Sharpei (China)
- I-Shih Tzu (i-Tibet, i-China)
Kodwa-ke, impendulo yokugcina yombuzo, yiziphi izinja ezindala kakhulu, ingatholakala uma zonke izinhlobo zanamuhla zihlolwa.
