Kusukela eLamarck kuze kube namuhla, ngidlula emibonweni kaDarwin, ukuvela kwentamo yendlulamithi bekulokhu kuyisikhungo salo lonke uphenyo. Kungani intamo yendlulamithi inkulu? Uyini umsebenzi wakho?
Lokhu akusiyo kuphela into echaza izindlulamithi, zingesinye sezilwane ezinkulu kunazo zonke ezihlala eMhlabeni manje, futhi esinye sezinzima kakhulu. Kule ndatshana kaPeritoAnimal, sizokhuluma ngayo ngoba intamo yendlulamithi inkulu kanye nezinye inhlebo ngalesi silwane sihle futhi sithakazelisa.
Intamo nendlulamithi yendlulamithi
Umgogodla uyisici esichaza iqembu elikhulu lezilwane, ama-vertebrate. Uhlobo ngalunye lune- umgogodla owodwa, yenzelwe izidingo ezithile zala maqembu ezilwane.
Imvamisa, umgogodla isukela ezansi kogebhezi iye ebhandeni lokhalo futhi, kwezinye izimo, iyaqhubeka nokwakha umsila. Iqukethe izicubu zethambo nezama-fibrocartilaginous, ezakhiwe kuma-disc noma ama-vertebrae ahlangana. Inani lama-vertebrae nokuma kwawo kuyahlukahluka ngokuya ngezinhlobo ezihambelanayo.
Ngokuvamile, kukholamu lomgogodla kukhona amaqembu amahlanu omgogodla:
- Umlomo wesibeletho: ihambelana nama-vertebrae atholakala entanyeni. Okokuqala, okunamathisela kugebhezi, kubizwa ngokuthi "i-atlas" bese kuthi "i-eksisi" yesibili.
- i-thoracic: Kusukela phansi entanyeni kuye ekugcineni kwesifuba, lapho kungasekho khona izimbambo.
- AmaLumbars: yi-vertebrae yesifunda se-lumbar.
- engcwele: amathambo ahlangana okhalweni.
- I-Coccygeal: ukuphela kwama-vertebrae ezilwane ezinama-vertebrate ezinomsila.
Izindlulamithi Izici Ezingokomzimba
Indlulamithi, Indlulamithi camelopardalis, kuyinto unguligrade okwe-oda le-Artiodactyla, njengoba ineminwe emibili emzimbeni ngamunye. Yabelana ngezici ezithile nezinyamazane nezinkomo, isibonelo, njengoba isisu saso sinamagumbi amane, iyi- isilwane esikhanyayo, futhi ayinayo i-incisor noma i-canine amazinyo emhlathini ongenhla. Futhi inezici ezihlukanisa lezi zilwane: its izimpondo zimbozweisikhumba futhi imihosha yayo engezansi inama-lobes amabili.
Ingesinye sezilwane ezinkulu nezisindayo emhlabeni. Zingafinyelela cishe kumamitha ayi-6 ukuphakama, indlulamithi endala ingafinyelela ithani nohhafu wesisindo.
Yize abantu abaningi bezibuza ukuthi mangaki amamitha intamo yendlulamithi okuqinisekile ukuthi, ngaphandle kwalokho, kunjalo isilwane esinemilenze emide kakhulu. Amathambo eminwe nezinyawo made kakhulu. I-ulna kanye nobubanzi bezingalo zangaphambili kanye ne-tibia ne-fibula yangemuva kuvame ukufuthwa futhi futhi zinde. Kepha amathambo empeleni ahlukaniswe kulolu hlobo ngamathambo ahambelana nezinyawo nezandla, okungukuthi, i-tarsi, imetatarsals, i-carpus kanye ne-metacarpals. Izindlulamithi, njengawo wonke ama-unguligrade, hamba ngentambo.
Mangaki amathambo omgogodla entanyeni yendlulamithi?
intamo yendlulamithi weluliwe, njengemilenze nje. Abanaso isibalo esikhulu kakhulu sama-vertebrae, iqiniso ukuthi la ma-vertebrae anjalo ihaba ngokweqile.
Njengazo zonke izilwane ezincelisayo ngaphandle kwama-sloth nama-manatee, izindlulamithi zinakho ama-vertebrae ayisikhombisa entanyeni, noma amathambo omlomo wesibeletho. I-vertebrae yendlulamithi yesilisa esekhulile ingalingana ize ifinyelele kumasentimitha angama-30, ngakho-ke intamo yayo, isiyonke, ingalingana kuze kufike 2 amamitha.
I-vertebra yesithupha entanyeni yama-unguligrade ihlukile ngesimo kunaleyo yonke, kepha ezindlulamithi icishe ifane neyesithathu, yesine neyesihlanu. I-vertebra yokugcina yomlomo wesibeletho, eyesikhombisa, nayo iyafana nezinye, ngenkathi kwamanye ama-unguligrade le vertebra yokugcina yaba i-vertebra yokuqala yesifuba, okungukuthi, inezimbambo ezimbili.
Yini intamo yendlulamithi?
Kusuka kuLamarck nombono wakhe wokuvela kwezinhlobo zezinto eziphilayo, ngaphambi kombono kaDarwin, i Ukusetshenziswa kwentamo yendlulamithi kwase kuxoxwa kakhulu ngakho.
Izifundo zakuqala ziphakamisa ukuthi ubude bentamo yendlulamithi wakhonza ukufinyelela amagatsha aphakeme kakhulu weumuthi womtholo, izihlahla ezidluliswa izindlulamithi, ukuze abantu abanezintamo ezinde babe nokudla okuningi abanakho. Le mbono yahlanjalazwa kamuva.
Okubonwa yilezi zilwane kufundiswa ukuthi izindlulamithi zisebenzisa izintamo zazo ukuvikela kwezinye izilwane. Bayayisebenzisa nangesikhathi sokuqomisana, lapho izindlulamithi zesilisa zilwa zodwa, zishaya izintamo nezimpondo.
Amaqiniso ayi-9 amnandi ngezindlulamithi
Ngaphezu kwemibuzo esishilo ekuqaleni ukuthi mangaki amathambo omqolo onentamo yendlulamithi, mangaki amamitha entamo yendlulamithi, ngoba intamo yendlulamithi inkulu, lena eminye amaqiniso amnandi ngezindlulamithi kuthakazelisa ngokwengeziwe nokuthi awuzange nakancane wazi:
- Izindlulamithi zilala phakathi kwemizuzu engama-20 kuya emahoreni amabili ngosuku;
- Indlulamithi ichitha usuku lonke izinyawo zayo;
- Amasiko wokukhwelana wendlulamithi athatha imizuzu emibili kuphela;
- Izindlulamithi ziyizilwane ezinokuthula okukhulu;
- Izindlulamithi ziphuza amanzi amancane kakhulu;
- Esinyathelweni esisodwa indlulamithi ingafinyelela kude ngamamitha ama-4;
- Izindlulamithi zingafinyelela ku-20 km / ihora;
- Ulimi lwendlulamithi lungafinyelela kuma-50 cm;
- Izindlulamithi zenza imisindo efana nomtshingo;
Funda kabanzi mayelana nezindlulamithi kulesi sihloko se-PeritoAnimal.
Uma ufuna ukufunda izindatshana eziningi ezifana ne- Ngoba intamo yendlulamithi inkulu, sincoma ukuthi ufake isigaba sethu se-Curiosities somhlaba wezilwane.
