Puas muaj ob txhais ceg ants muaj? Cov lus teb rau lo lus nug yog pom tseeb: zoo li txhua tus neeg sawv cev ntawm kab, rau. Ntxiv mus, tus naj npawb ntawm ob txhais ceg yog ib qho ntawm cov cim qhia ntawm chav tsev taxonomic ntawm arthropod hom tsiaj lub nceeg vaj.

Pant yog ib yam kab ntau heev. Raws li cov kws tshaj lij, tag nrho qhov loj ntawm lub ntiaj teb cov ntsaum yog los ntawm kaum mus rau nees nkaum feem pua ntawm tag nrho cov biomass (qhov loj ntawm tag nrho cov tsiaj nyob, nrog rau cov nroj tsuag thiab cov kab mob) ntawm lub ntiaj teb. Muaj tseeb, nws yog qhov nthuav: yuav ua li cas yog qhov kev suav ntawm biologists? Thiab feem ntau, puas muaj ib txoj hauv kev uas tso cai rau koj los xam qhov loj ntawm ib hom, genus, kev txiav txim lossis chav kawm ntawm cov tsiaj? Feem ntau, qhov yuam kev ntawm kev suav yuav yog qhov tseem ceeb heev.

Pants cais los ntawm kab mus rau hauv tsev neeg ywj pheej ntev dhau los. Thawj cov tib neeg tau sau tseg los ntawm paleontologists nyob rau hauv lub hnub nyoog ntawm kev kav ntawm dinosaurs - txog ib puas thiab xya caum lab xyoo dhau los. Thawj cov ntsaum yog primitiveqauv (piv rau cov ntsaum niaj hnub). Niaj hnub no, ob hom kab ntsaum tau muaj sia nyob, yuav luag tsis hloov txij li lub sijhawm ntawd. Cov no yog cov hu ua "living fossils". Thawj tus tau pom hauv tebchaws Australia xyoo 1931 (dinosaur ntsaum), thiab qhov thib ob tau pom hauv Brazil tsuas yog tsib xyoos dhau los. Cov ntsaum muaj pes tsawg ceg thaum dinosaurs roamed lub ntiaj teb? Cov kws tshawb fawb tsis sib haum xeeb: rau! Txij thaum ntawd los, qhov no yog qhov sib txawv ntawm kab thiab arthropods ntawm lwm chav kawm.

Arthropods, suav nrog ntau tus tsiaj hauv av thiab hauv hiav txwv, tau muab faib ua ntau hom. Tsis paub tus lej pes tsawg, vim kev tshawb pom tshwm sim tsis tu ncua. Yog li ntawd, txawm tias cov kws tshaj lij pom tias nws nyuaj los teb - ntau npaum li cas. Ib txwm muaj rau ceg ntawm kab, yog li nws yooj yim los twv tias, piv txwv li, kab laug sab tsis nyob hauv lawv. Yog tias koj tsis tau xav txog tam sim no, ces nyob rau qee lub sijhawm suav nws ob txhais ceg. Yuav muaj yim ntawm lawv. Kab laug sab, zoo li kab, yog hom ntawm arthropods, lawv txawv nyob rau hauv nws nyob rau hauv ib tug nyias muaj nyias tsev neeg ntawm arachnids. Cov tsev neeg no kuj suav nrog chav kawm ntawm cov zuam uas paub zoo. Yog lawm, lawv kuj muaj yim ceg. Xws li cov zuam encephalitic, uas yuav tsum ntshai thaum mus xyuas sab qaum teb thiab Siberian hav zoov.

Nws yuav zoo li txhua qhov no tsis nyuaj, thiab yog li nws tseem nco qab zoo. Txawm li cas los xij, feem ntau thaum kawm biology hauv tsev kawm ntawv, ua ntej cov lus nug ntawm pes tsawg ceg ntsaum muaj, tsis txaus siab rau cov tub ntxhais kawm poob rau hauv stupor. Nws yuav zoo li koj pom cov kab no yuav luag txhua hnub, tab sis qee qhov koj tsis thab suav koj ob txhais ceg.

At peb ob txhais ceg muaj zog heev. Raws li biologists, peb cov ntoo liab zoo tib yam muaj peev xwm nqa tau nees nkaum npaug ntawm nws tus kheej. Yog hais tias qhov piv ntawm lub zog ntawm ceg thiab lub cev qhov hnyav nyob rau hauv ib tug neeg yuav zoo ib yam li nyob rau hauv ib tug ntsaum, nws yuav khiav ntawm qhov ceev ntawm ib tug thoroughbred racehorse. Txhua tus ntsaum ob txhais ceg muaj peb pob qij txha. Lub sab sauv yog tus ncej puab, qis dua yog sab ceg, thiab ntawm qhov sib txuas muaj qhov spur. Qhov qis tshaj ntawm tus ntsaum ceg yog hu ua paw. Thaum kawg ntawm ko taw yog tus hu ua claw.

Qee lub sij hawm cov kws tshawb fawb tsis ntseeg tias chav kawm twg los yog xaj kom ntaus nqi no lossis tus neeg sawv cev ntawm arthropods. Thiab txawm hais tias lub taxonomy ntawm flora thiab fauna yog ntau dua los yog tsawg zoo-tsim khoom, kev tsis sib haum xeeb ntawm biologists tsis ploj mus rau hnub no. Oddly txaus, hom tshiab ntawm invertebrates tau pom txhua xyoo, txawm hais tias nws yuav zoo li tias lub ntiaj teb tau tshawb pom deb thiab dav! Thiab txawm hais tias cov lus nug ntawm pes tsawg ob txhais ceg ants muaj tsis yog ib qho tseem ceeb, nws muaj peev xwm hais tias qhov kev xav ntawm biologists txog qhov chaw thiab lub luag haujlwm ntawm cov neeg sawv cev ntawm cov kab sib sau ua ke hauv kev hloov pauv ntawm lub neej hauv ntiaj teb yuav hloov kho thiab ua kom zoo li peb. kev paub ntawm lub ntiaj teb nce.
