Umsindo Wehhashi

Ihhashi isilwane esincelisayo esifuywe ngezinselo. Ingowomndeni we-taxonomic Equidae futhi ingenye yezinhlobo ezimbili ezikhona ze-Equus ferus. Ihhashi selishintshile eminyakeni eyizigidi ezingama-45 kuya kwezingama-55 lisuka esilwaneni esincane esinezinzwane eziningi, i-Eohippus, kuya esilwaneni sanamuhla esikhulu, esinozwane olulodwa. Abantu baqala ukufuya amahhashi cishe ngo-4000 BC, futhi ukufuywa kwawo kukholakala ukuthi kwasakazeka kabanzi ngo-3000 BC. Amahhashi afuywa ezihlotsheni ezingaphansi zeCabalus, nakuba ezinye izizwe ezifuywayo zihlala endle njengamahhashi asendle. La maqembu ezilwane ezifuywayo awawona amahhashi asendle eqiniso, njengoba leli gama lisetshenziselwa ukuchaza amahhashi angakaze afuywe. Kukhona isilulumagama esikhethekile esibanzi esisetshenziselwa ukuchaza imiqondo ehlobene namahhashi, ehlanganisa yonke into kusukela ku-anatomy kuya ezigabeni zokuphila, ubukhulu, imibala, izimpawu, izinhlobo, ukunyakaza, nokuziphatha.

Amahhashi ajwayele ukugijima, okuwavumela ukuba abaleke ngokushesha ezilwaneni ezidla ezinye, abe nomqondo omuhle kakhulu wokulinganisela kanye nokusabela okuqinile kokulwa-noma-ukundiza. Okuhlobene nalesi sidingo sokubalekela izilwane ezidla ezinye endle kuyisici esingavamile: amahhashi ayakwazi ukulala emile futhi elele, namahhashi amancane avame ukulala kakhulu kunabadala. Amahhashi ezinsikazi, abizwa ngokuthi ama-mares, athwala amazinyane awo izinyanga ezingaba ngu-11, kanti ihhashi elincane, elibizwa ngokuthi ithole, lingama futhi ligijime ngokushesha ngemva kokuzalwa. Amahhashi amaningi afuywayo aqala ukuqeqeshwa engenalutho noma eboshwe phakathi kweminyaka emibili nemine. Bafinyelela ekukhuleni okuphelele kwabantu abadala lapho beneminyaka emihlanu ubudala, futhi banesilinganiso sokuphila esiphakathi kweminyaka engama-25 nengama-30.
