Ihhashi lokuqala, iHyracotherium

Kuthiwani I-Hyracotherium, ihhashi lohlobo lohlobo lwe izilwane ezincelisayo ze-perissodactyl, nayo leyo engukhokho ofanayo nowabhejane kanye ne-tapir. Kungakho-ke, ake sithi, ihhashi lokuqala esinedatha yalo.

Kwakuyisilwane esine-quadruped esasihlala ezindaweni eziseNyakatho Melika, enyakatho yeYurophu, nasenyakatho ye-Asia ngesikhathi se-Eocene, cishe esukela ephakathi kweminyaka engama-60 nengama-45 million edlule. Lesi silwane savela saba yi-Oligohippus, kamuva salandelwa iMerichippus, kwalandela iPliohippus futhi ekugcineni ihhashi, lonke uchungechunge olude lokuziphendukela kwemvelo laze lafinyelela kulokho esikwaziyo namuhla njenge-equines.


Lesi silwane sasidla imifino encane cishe cishe usayizi wempungushe, ifinyelela cishe kumasentimitha angama-35 futhi inesisindo esiphakathi kwamakhilo ayisihlanu kuya kwayisikhombisa. Bekufakwa izinzwane ezintathu emilenzeni yangemuva nezine emilenzeni yangaphambili, zona zivikelwe izinselo, olumaphakathi lube banzi futhi lube lude.

Noma ngabe umehluko omkhulu ngesikhathi phakathi kwehhashi neHyracotherium, owokugcina oshiwo bekuvele kufana kakhulu nenzalo yakhe yamanje, yize behluke ngokomzimba njengosayizi. Ngokocwaningo oluthile, lezi zilwane zazihlala emahlathini anezinhlobo eziningi.

Amazinyo akhe aguqulelwe i- ukudla amaqabunga omuthi wethenda, ngenkathi amehlo akhe ayetholakala enkabeni yekhanda lakhe, engamvumeli umbono omkhulu we-lateral, isici esizihlukanisa ngokuphelele namahhashi ngoba badinga umbono wakhe oseceleni wokuzivikela okukhulu. Ngokusobala iHyracotherium noma i-Eohippus njengoba yaziwa futhi, lolu hlobo lokubuka eceleni lwalungasizi ngenxa yendawo elalihlala kuyo, lolo hlobo lokufihla lwalusebenza kangcono ukuxosha izilwane ezidlayo.
