evolution

El kumu kumu lio loaʻa mai kahi ʻano o ka perissodactyl mammal, nona ia ʻohana equidae. Aia kēia ʻohana i ʻekolu mau pūʻulu o nā māmela hihiu: zebras, ʻōiwi no ʻApelika. ʻO Asses, kahi e hoʻopili ai i ka hoki hihiu ʻApelika a me ke kiang a me ka mea holo, e noho ana ma ʻAsia.

Hiki ke ukali i ka evolution o ka lio moʻolelo fossil iā Hyracotherium, he mammal lau nahele liʻiliʻi i noho i ka wā o ka Eocene. ʻO ka Hyracotherium kahi holoholona e like me ka nui o ka ʻalopeke, a ʻehā mau manamana wāwae ma kona mau wāwae mua a ʻekolu ma kona mau wāwae hope.


I ka Miocene ua lanakila ʻo Mesohippus Hypohippus a me Anchitherium, ʻO lāua ʻelua i hoʻokau ʻia ʻo Eurasia mai ʻAmelika Hema. ʻO nā moʻopuna ʻē aʻe a Mesohippus ʻo Miohippus lāua ʻo Merychippus, nā niho hope me nā lei aliʻi kiʻekiʻe loa, i ʻae iā ia e mākaʻikaʻi i nā lau a me nā wana o nā kumu lāʻau a me nā kumu lāʻau.

Mawaena o na pua a ʻO Merychippus ua Hipopotamu, i ka wā o ka Pliocene neʻe a hoʻonui ʻia mai ʻAmelika Hema a i Eurasia, a ʻo Pliohippus, ʻo ia paha ka kūpuna o ka lio o kēia manawa, ʻo ia ka genus Equus.

He lio ko kēia lio hoʻokahi manamana ma luna o kēlā me kēia lālā. No kēia kumu ua manaʻo ʻia he perissodactyl, ʻo ia hoʻi, he ungulate mammalian nona nā wēlau e hoʻopau i nā ʻūlū me nā helu manamana ʻokoʻa. Loaʻa i ke kauoha Perissodactyla nā lio, nā rhino, a me nā tapir.

Ua lilo ka manamana o ka lio i lōʻihi loa a pale ʻia e ka ʻāho hoʻoweliweli Hoʻopuni wale ia i mua a me ka ʻaoʻao o ka wāwae. ʻO nā manamana wāwae ʻelua a ʻehā hoʻi i ke kanaka he vestigial ia, koena atrophied o nā manamana lima hana, a aia ma luna a ma nā ʻaoʻao ʻelua o ka hoof.

Lōʻihi nā iwi o ke poʻo o ka lio a ʻo nā maka o ka maka ʻelua manawa ka lōʻihi o ka iwi poʻo. Lōʻihi, ākea a pālahalaha ka iwi ā lalo i ka ʻaoʻao haʻahaʻa o ka ʻaoʻao hope. Hana ʻia ke kolamu spinal o 7 cervical, 18 dorsal, 6 lumbar, 5 Sacal, a me 15 caudal.

He aha ka equine

Hoʻopili ka ʻike o ka ʻatikala i kā mākou kumumanaʻo o ka hoʻoponopono hoʻoponopono. E hōʻike i kahi kaomi hemahema ʻaneʻi.

E lilo i mea mua e wehewehe

E waiho i kāu manaʻo

Kāu leka uila aae? E,ʻaʻole e paʻiʻia.
