Chordates - holoholona ua wehewehe aku e ka luna '' ole a me ka likeʻole ma

Chord - o ka loa i aloha i hoʻonohonoho 'ia mea, mai lala a pau o ka holoholona aupuni. Ke ano hiʻona o ka 'ole' ae 'ia e lilo i ka oioi o ka evolution.

na hoailona o ka chordates

Ke kumu nui hiʻona o kēia mau holoholona o ke alo o ka chord, neural Tube a me ka halo o mua oä i loko o ka pharynx. Chordates - i hiki me ka nui loa meaola i i helu 'ia ma nā hōʻailona Hoʻololi'.

Penei, o ka iwi i ia i ka pahale mawaho, a me ka pā. A hooulu ana o chordates ma ontogenesis hiki ke wehewehe aku ma ka mea i ka halo o mua oä ulu nō i loko o ka embryonic kūpono 'ana o ka meaola. I ka Ia manawa ka mea, e ulu 'ē aʻe naehana'ōnaehana - ka lewa sacs paha ia maʻiʻaʻai.

iho iwi

I ka papa kuhikuhiE ano o chordates - o ke alo o ka chord. He he na iho iwi, i mea ma ka palapala o kaʻaha hele ma ke kino holoʻokoʻa. Ma kona ola ana, i ka chord mea,ʻaʻole nui ka poeikohoia o kēiaʻano. Mau nāʻano a Amphioxus, no ko ka papa Golovohordovye subtype invertebrates.

ʻO nā 'elele o ka notochord e hoʻomōhala ana i loko o ka iwi. Wale nō ma kekahi mau mea, ua i mai o ka cartilage. Pokou iʻa, amphibians, mea kolo, a me nā manu mammals ua pau ossified iwi. Ma ke kaʻina hana o ka evolution ia mea huikau. He hapa o ka puniu wale no, spine, umauma, pūhaka, a pono maluna, a malalo lala.

Halo o mua oä i loko o ka puu

Chordates - nā holoholona nona ka naehana nā loko e hanaʻia me ka outgrowth o ka pharynx. Kēia mea kā lākou mau papa okoa mai invertebrates. Ma keia hui, i loko ka mea, mai ka lala.

O ka holo ana, i ka anatomical hiʻona i ole a pau chordates. Halo o mua oä i waiho ai i loko o Amphioxus a me cartilaginous iʻa: mano a me nā kukuna. Nā holoholona, a i hakuloli i ha ka lewa oxygen, ma na kahua o ka hoʻonaʻauao kakahiaka o embryonic? Acaeoey, ka mea, e ulu. Ma hope o ho okumu i ka ia maʻiʻaʻai.

Hiʻona o ka'emi ko kahua

Ka'ōnaehana hoomaopopo ana interconnection me ke kaiapuni, ma chordates initially i hanaʻia ma luna o ke 'ano o ka neural Tube. Ua loaʻa ectodermal kumu.

Chordates - he lahui Hawaiʻi holoholona Ua pili kēia i ke 'o ka' ole o ka'emi ko kahua. No ka laʻana, ma mammals ka mea, ua poe ma ka spinal kaula, i ua aia i loko o ka spinal Canal, e like me ke poo. Ka mea, i kekahi hapa o ka Central ko mākou hopohopo nenoaiu. Ka lolo Ua palekana na iwi o ka puniu wale no, a ua fixedly pili. He ua differentiated i loko o māhele ka nānā 'ana ma luna o kuleana pili i. Anatomically ma ka puka i hanaʻia ma ka vertebrae, ka lolo ua pili i ka spinal kaula. ʻike ākea nenoai hana kekahi hapa o ke kua - a cranial nā aʻalolo. Ka mea, e malama nei me "amo ala hele", hoʻohuiʻia i ka luna 'meaola i loko o ka hoʻokahi a pau, a me ka coordinating i ka hana.

Ka 'ole o ka'emi'ōnaehana ke kumu o ka luna' hana o chordates, ke kahua o ka hoʻoponopono reflexes a me ka mōakāka ka polokalamu o ka pii ana.

Aʻano o nā chordates

Kēiaʻano nā ekolu subtypes: bescherepnyh, Lichinochnohordovye (tunicate) a me Cranial (vertebrates).

I ka mua o ia kēia? Ueo 'ia i loko o mākou manawa wale 30. Lākou mau 'elele i Amphioxus. Mau holoholona e hoohalike ai ʻoki lāʻau lapaʻau mea kani i kapaʻia he lancet.

Ke kino o kēia mau holoholona liilii, Ua kokoke mau ka hapalua i loko o ke one. Pela Amphioxus maʻalahi e wae i ka wai, moni 'ia nutritive (particles).

Ka loa nui subtype o chordates i vertebrates. Ka mea, ua E ke Kumu a pau, kaianoho koholā, ai kaulahao, a hoʻopiha ? Aneeo niches.

Wai poʻe e noho ana i ka iʻa. Lākou Hoʻoponopono kino uhiia me ka unahi, ka mea i hakuloli i ka halo o mua hanu, neʻe ma kumu o ka halo.

hookuu mua ma luna o ka'āina, he amphibians. Ua rana, toads, newts, ilo a me ka ichthyophiidae. Lākou, he pono ole ka inoa e hele mai, mai ka mea e ola ka mea, ma luna o ka'āina a me ka hanu ma ia maʻiʻaʻai a me ka ili, akā, i ke kaʻina o nā'ōlelo i wahi i loko o ka wai. Like iʻa, wahine spawn kā lākou hua i loko o ka wai, a ua nininiia maluna o ke kane semen.

Nō kāu ano honua kahi holoholona - ka mea, Aloha creepy. Moo, nahesa, manu kuhukukū, a crocodiles lawe mai i loko o ka wai wale i imi mea hihiu ana. Ka mea, paʻi hua e moe ana ma kūikawā hale kamala ma ka aina. Ko lakou ili, ua maloo, uhi me ka manoanoa unahi.

Ka hope hiʻona ili mai ka mea kolo, manu. Neoperennaya kauwahi o ko lākou mau wāwae ua kapaia he bobbin. Ua ua ia, a ua uhiʻia me ka uuku unahi. Keia mea, ua manaoia epekema e like me ka maopopo ana o ka kumu o ke kaʻina hana o ka evolution. e hiki ke lele i ke aloha a hiki i ka nui hiʻona o ka mawaho, a maloko 'ole manu. Kēia Hoʻololi 'forelimbs, hulu, Lightweight iwi, i ke alo o ka keel - i lalo iwi, a e pili ana i na nāʻiʻo, kūpono ma ka holo ana o na eheu.

Eia hoi, Animals a me Mammals i ka lei o ka evolution. Ka mea, e viviparous a me ka hānai keiki bipi waiu.

Chordates - ka loa complexly, ka nohona i ka 'ole, pāʻani nui he kūlana ma ke' ano a me ka kanaka ola.
