Imbwa dzinoperekedza vanhu kusvika rinhi? Vatsvakurudzi vepaYunivhesiti yeArkansas vakazvibvunza mubvunzo uyu uye vakaona kuti imbwa inogona kunge yakachengetwa munguva yeIce Age.
Ongororo yakaitwa pazino riri muchisaririra wemakore anenge 28,500 XNUMX kubva kuCzech Republic inoratidza kuti panguva iyoyo pakanga patova nemisiyano pakati pemhuka dzembwa nemhumhi. Zvokudya zvakasiyana-siyana zvinoratidza kuti panguva ino imbwa yakanga yatopingudzwa nevanhu, ndiko kuti, kuchengetwa semhuka dzinovaraidza. Iyi ndiyo mhedziso yavakawana muongororo yavo ichangoburwa.
Kuti vaite izvi, vakaongorora uye vakaenzanisa zvinyama zvemazino emhumhi uye mhuka dzembwa. Masayendisiti akacherechedza maitiro asingakanganisi aisiyanisa imbwa kubva kumapere. Mazino embwa dzeIce Age aive nemakwara akawanda kupfuura mapere ekutanga. Izvi zvinoratidza kuti vaidya chikafu chakaoma uye chisina kusimba. Semuenzaniso, mapfupa kana zvimwe zvikafu zvevanhu.
Humbowo hweImbwa Dzinodzokera Kumashure Kwemakore 28,000
Ukuwo madzitateguru emapere akadya nyama. Semuenzaniso, tsvakiridzo yapfuura inoratidza kuti mhuka dzakaita semhumhi dzingave dzakadya nyama yemammoth, pakati pezvimwe zvinhu. "Chinangwa chedu chikuru chaiva chekuongorora kana mamorphotypes aya ane maitiro akasiyana zvakasiyana-siyana zvichienderana nemapfekero," anotsanangura kudaro Peter Unger, mumwe wevatsvakurudzi, kuScience Daily. Iyi nzira yekushanda inovimbisa zvikuru kusiyanisa kubva kumapere.
Kuchengeta imbwa semhuka dzinovaraidza kunoonekwa senzira yekutanga yekuchengeta mhuri. Kunyange vanhu vasati vatanga kurima, vaichengeta imbwa. Pasinei neizvi, masayendisiti achiri kukakavadzana kuti riini uye nei vanhu vakapfuya imbwa. Zvinofungidzirwa kuti kubva 15,000 40,000 kusvika XNUMX XNUMX makore apfuura, ndiko kuti, panguva Ice Age.
