Qhov sib txawv tseem ceeb ntawm apterygota thiab pterygota yog tias apterygota yog ib pawg kab ntawm cov kab uas muaj cov kab tsis muaj tis, thaum pterygota yog ib pawg kab ntawm cov kab uas muaj cov kab tis.
Kab yog pawg loj tshaj plaws nyob rau hauv lub arthropod phylum. Lawv kuj yog pab pawg tsiaj uas muaj ntau haiv neeg. Feem ntau, ib kab muaj chitinous exoskeleton, peb lub cev, peb khub ntawm ob txhais ceg, ob lub qhov muag, thiab ib khub ntawm lub kav hlau txais xov. Muaj ntau tshaj li ib lab tus kab piav qhia. Lawv kuj sawv cev ntau dua ib nrab ntawm tag nrho cov kab mob uas muaj sia nyob. Tsis tas li ntawd, kab nyob ze ntawm txhua qhov chaw. Kwv yees li ntawm 90% 0f tsiaj cov ntaub ntawv hauv ntiaj teb yog kab. Apterygota thiab pterygota yog ob subclasses ntawm kab.
Apterygota yog dab tsi?
Apterygota yog ib pawg kab ntawm cov kab uas suav nrog cov kab tsis muaj tis. Nws kuj yog ib tug subclass ntawm me agile kab. Cov kab no txawv ntawm lwm cov kab los ntawm lawv qhov tsis muaj tis tam sim no thiab hauv lawv cov keeb kwm evolutionary. Cov subclass no feem ntau suav nrog silverfish, firebrat, thiab dhia bristletails. Lawv thawj qhov tshwm sim hauv pob txha pob txha raug kaw thaum lub sijhawm Devonian. Qhov ntawd yog 354 txog 417 lab xyoo dhau los.

Nyob hauv lawv lub neej, cov nymphs (theem yau) mus txog me me lossis tsis muaj metamorphosis. Cov theem yau li no zoo li cov neeg laus cov qauv. Daim tawv nqaij ntawm kab ntawm no subclass yog nyias, ua rau lawv pom translucent.

Ntxiv mus, tam sim no, tsis muaj hom ntawm cov subclass no tau teev nyob rau hauv cov npe kev txuag kev pheej hmoo.
Feem ntau, lo lus Apterygota yog hais txog ob kab kab sib cais uas tsis muaj tis: Archeognatha thiab zygentoma. Archeognatha suav nrog dhia bristletails. Ntawm qhov tod tes, zygentoma suav nrog silverfish thiab firebrat. Tsis tas li ntawd, hauv taxonomy, apterygota yog ib pawg paraphyletic.
Pterygota yog dab tsi?
Pterygota yog ib pawg kab ntawm cov kab uas suav nrog cov kab tis. Nws kuj suav nrog cov kab uas tsis muaj tis thib ob. Secondarily wingless yog hais txog nws cov poj koob yawm txwv ib zaug muaj tis tab sis tau poob lawv raws li qhov tshwm sim tom qab evolution. Cov pab pawg pterygota suav nrog yuav luag txhua cov kab tshwj tsis yog archeognatha thiab zygentoma, uas yog apterygota. Cov pab pawg no tsis suav nrog peb qhov kev txiav txim, proturan, clollembola, diplura, vim lawv tsis suav tias yog kab ntxiv lawm.

Keeb kwm ntawm kab ntawm no subclass kuj rov qab mus rau lub sijhawm Devonian. Pterygota subclass hom ib txwm qhia metamorphosis. Tsis tas li ntawd, lawv cov neeg laus tsis muaj pwm thiab tsis muaj cov kab mob hauv plab. Lub mandibles ntawm cov kab no yog articulated nrog lub taub hau capsule ntawm ob lub ntsiab lus. Cov kab paub zoo tshaj plaws ntawm cov subclass no suav nrog mayfly, dragonfly, thiab lwm yam.
