Kiel - kēia ... No ke ahaʻo ia e pono ai i ka manu

Mammals a me na manu - o ka oioi o ka evolution o vertebrates. ka mea, o ka poe iʻikeʻia, a puni ka ia manawa. ʻO loko o ka Triassic wā e noho ana i ka wā mammals, a i kaawale mai dinosaurs. Ka mea, ua primitive, aʻaʻole i nā mea a pau reminiscent o kēia holoholona. I ka hoʻomaka o ka Canyon wā mai ano honua kahi hana o ua moo i hele mai lele manu, a ua haawi ala i ka papa o ka manu.

Mea kolo nohoʻoleʻia i ka holoʻokoʻa ?? eoi? Ee, i 'ae' e hoopau i ka manu mua, a mammals i loko o ka noa nā panalāʻau e. A me ka mea e lanakila hou ka aina, i i ole mua, ua hoʻohana 'ia o ua moo nei, ka pilina i ka mea i mammals a me nā manu ikea adaptations no ola i loko o ka likeʻole ma o aku ana. Hana o ua moo - kēia mau mea i ka papa kuhikuhiE nā kānaka hoʻokūkū, hoomaikai ia ia i ka manu hou ko mākou hopohopo'ōnaehana, ano nā loko a me ka hana. I kēia lā mākou e pololei ai hoihoi i loko o ka 'ole o ka mea. Mākou e kaumaha no ka ike me kēia māhele o ke kino e like me ka keel. Kēia manaʻo mea, i loko o na manu a me nā holoholona. He aha ia mea, i hana i ka hanaia, mākou i keia hana aʻo.

Ka 'ole o ka manu

He nui na manu e lele, kekahi i loko o ka papa o ka evolution, ua nalowale keia hana. Ano, e ka kamailio iki e pili ana i ka 'ole o ka maʻiʻaʻai a me ea mea. Omo iwi, paʻa kūhohonu loa Lime paakai, ae na manu e lele, no ka mea, nui ikaika a me ka malamalama i ko lakou mau iwi lilo. Ka iwi poʻo i nā hiʻona manu: ma ka muaʻaoʻao wale nui maka mau kumu, a me ka nuku, a mua i ka iwi ā me ka niho.

'ā'ī kekahi lōʻihi a me ka hoʻoneʻe, ka mea, he umi i ka iwakalua-kumamalima vertebrae. E like me ka mea mua wāwae - i na mau eheu, me ka mahuahua haawe ana ma luna o nā wāwae: na iwi i lilo i ka pelvic hapa fused, no laila, ua lilo nui ka ikaika ka mea. Aia nā hiʻona i loko o ka 'ole o ka'ūhā mua' Oihana, no ka laʻana - ka keel. He He loa ikaika iwi, i lawelawe mauna no pectoral nāʻiʻo. E ka kamailio e pili ana i keia he iki hou.

Kiel

E like me mākou i mai la oia, i ka keel - keia outgrowth, i mea e pono ai hoʻopunipuni nā manu o ka pectoral nāʻiʻo. Kēia outgrowth i hana i loko o ke kaʻina hana o ka evolution, e like me na manu e lele i ke aloha i keia mea, no ka mea, ka mea pectoral nāʻiʻo i ulu loa ikaika. He mea ole wale manu, akā, i loko o kekahi mau holoholona, i mea mua wāwae i ka ikaika: like me ka rula, ka meaʻeli i ka lepo. An hana makemake e ke kameleona. Akā, oi loa aku hoi i ka hooulu ana o ka keel nō i ma lele manu,'ōpeʻapeʻa. Aia He oiaio, he ai-kapaia keel manu: hummingbirds, mama ko, a no laila, ma luna o. Oia hoi, ka mea hiki e mai la oia i ka keel - he paahana no ka manu a me ka burrowing na holoholona, me ka a lakou i wale hiki ole ke hana.

oihana

Kiel - kēia meaʻano nui i loko o na manu, pokou outgrowth i loko o ka thoracic spine, ia mea i lalo, ua hoʻohana 'ia e hoʻohui i kekahi' ano ikaika o nāʻiʻo kākou me ka neʻe. Kahińuli i ka papa kuhikuhiE manao a me ka hana ana o ka iwi ke kualono.

• Kiel mākou i pono, e hooikaika i ka thoracic spine, oa i ka iwi o keia hapa Ua mau nō. Mākou ke i aku nei au ia ia mea he hou i nā mea hana i ka nui nā loko, e hoʻopale ai.
• No ka manu ka wā e neʻe mau'ēheu komo loa i ka hailona o Muscle, ka keel ua lele aku ai i ka helu i ka nui o ke Muscle olona.
• Nō hoʻi, i kēia outgrowth paipai 'ana i ka hoʻoneʻe o ka thoracic. Ua apono 'oe e hana i ka neʻe' ana me ka hohonu hanu.
• Na hope kuleana pili i - he loli i loko o ka lele ala, ka keel mea i ka hope wahi i loko o kēia kaʻina.

Ma kekahi manu i keel

No laila, keel - He aha ka mea? Mākou wahi a kēia nīnau. Ua ua mai la ia he mea outgrowth o na manu, akā,ʻaʻole e kamailio e pili ana i hewa. He nui ka möakäka hou i loaʻa mea he subclass o ratites. Mua, ua kapaia ka mea, penei:
