Tichifunga ndima iyi pamusoro pokurera mhuka dzinoyamwisa, ndiudzei nguva yokutanga inozivikanwa umo kugadzirwa kwemukaka kwakaitika uye ndipeiwo nzvimbo yacho.
Context:Vanhu vakatanga kudzidza kudya mukaka wemamwe mhuka nguva dzose zvichitevera kugadziriswa kwemhuka munguva yeNeolithic Revolution kana kuti kukura kwekurima. Uku kukura kwakaitika zvakazvimiririra munzvimbo dzinoverengeka dzepasi kubva pakutanga sa9000<unk>7000 BC muMesopotamia kusvika 3500<unk>3000 BC muAmerica. Vanhu vakatanga kurima mhuka dzinokosha zvikuru dzinoshandiswa mukaka <unk> mombe, makwai nembudzi <unk> muSouthwest Asia, kunyange zvazvo mombe dzomumba dzakanga dzakatorwa nenzira yakazvimiririra kubva kuvanhu vemusango vemaurochs kanoverengeka kubvira ipapo. Pakutanga mhuka dzaichengeterwa nyama, uye nyanzvi yezvinocherwa mumatongo Andrew Sherratt akataura kuti kugadzira mukaka, pamwe chete nokushandiswa kwemhuka dzomumba nokuda kwebvudzi nebasa, kwakatanga gare gare mukushanduka kwezvinhu zvechipiri zvakasiyana mumireniyumu yechina BC. Muenzaniso waSherratt hauna kutsigirwa nezvakawanikwa munguva pfupi yapfuura, zvichibva pakuongororwa kwezvakasara zve lipid muzvidhinha zvekare, zvinoratidza kuti kugadzira mukaka kwaiitwa mumatanho ekutanga ezvekurima muSouthwest Asia, neanenge chiuru chemakore chechinomwe BC. Kubva kumaodzanyemba kwakadziva kumadokero kweAsia mhuka dzemukaka dzakapararira kuenda kuEurope (kutanga munenge muna 7000 BC asi hadzina kusvika kuBritain neScandinavia kusvikira pashure pa4000 BC), uye South Asia (7000<unk>5500 BC). Varimi vokutanga muCentral Europe neBritain vaiyamwa mhuka dzavo. Hupfumi hwekudyara zvipfuyo uye hwekudyara zvipfuyo, izvo zvinovimba zvakanyanya kana chete nemhuka dzekumba uye zvigadzirwa zvavo pane kurima zvirimwa, zvakagadzirwa apo varimi veEurope vakatamira kuPontic-Caspian steppe muzviuru zvina BC, uye vakazopararira munzvimbo zhinji dzeEurasia. Makwai nembudzi zvakaunzwa muAfrica zvichibva kuSouthwest Asia, asi mombe dzeAfrica dzingave dzakasununguka dzakapfuyiwa munenge muna 7000<unk>6000 BC.
Kurimwa kwemukaka kwokutanga kunozivikanwa kwakaitika pakati pe9000-7000 BC muMesopotamia.
