Qhov sib txawv tseem ceeb ntawm cov khoom tsim ntuj tsim thiab phylogenetic system ntawm kev faib tawm yog tias cov txheej txheem kev faib tawm yog qhov kev xaiv ntawm kev sib koom ua ke thiab pab pawg raws li, thaum lub ntuj tsim ntawm kev faib tawm yog pawg ntawm cov kab mob raws li qhov sib xws thiab txheeb xyuas cov yam ntxwv sib koom., thiab phylogenetic system ntawm kev faib tawm yog pawg ntawm cov kab mob raws li cov noob caj noob ces.
Nrog rau kev taw qhia ntawm txoj kev xav ntawm evolution, muaj qhov xav tau rau kev faib cov kab mob. Artificial, natural, thiab phylogenetic systems ntawm kev faib tawm tau tsim nyob rau lub sij hawm los faib cov kab mob nyob raws li qhov sib txawv.
Dab tsi yog Artificial System of Classification?
Kev faib khoom cuav yog ib qho kev faib tawm ntawm cov kab mob raws li cov yam ntxwv tsis hloov pauv uas tau xaiv los ntawm kev txiav txim siab thiab ua pawg raws li. Nyob rau hauv cov txheej txheem ntawm kev faib tawm no, ob peb tus yam ntxwv yooj yim pom tau raug txheeb xyuas arbitrarily thiab ua raws los ntawm kev faib cov kab mob raws li. Cov txheej txheem ntawm kev faib tawm no yog qhov tseem ceeb ntawm 300BC txog 1830. Yog li ntawd, nws yog hom kev faib tawm qub tshaj plaws uas siv rau pawg kab mob.
Qhov txiaj ntsig tseem ceeb ntawm kev faib tawm dag yog tias cov txheej txheem ntawm kev faib tawm yog qhov ruaj khov thiab txhim kho yooj yim. Yog li ntawd, lub caij nyoog ntawm kev hloov yog txwv heev. Tab sis vim qhov yooj yim ntawm cov kev faib tsis, kev faib khoom cuav tsis qhia txog kev sib raug zoo. Yog li, qhov kev faib tawm no tsis tshua muaj thiab tsis tshua siv. Piv txwv li, thaum faib whales los ntawm lub xub ntiag ntawm fins, lawv yuav raug cais raws li qeb ntawm cov ntses (Class Pisces). Ib yam li ntawd, thaum faib cov qwj los ntawm lub xub ntiag ntawm lub plhaub, lawv yuav raug cais nrog cov vaub kib thiab tsis yog squids. Qhov no yog qhov teeb meem tseem ceeb ntawm kev faib khoom cuav.
Natural System of Classification yog dab tsi?
Natural classification yog ib hom kev faib khoom siv los faib cov kab mob raws li qhov zoo sib xws thaum xub thawj thiab tom qab ntawd txheeb xyuas lawv cov yam ntxwv sib koom. Qhov kev faib tawm no muaj kev sib raug zoo ntawm kev hloov pauv txij li qhov system no cais cov kab mob raws li kev sib koom ua ke. Kev faib tawm ntuj yog lub hauv paus ntawm kev faib cov txheej txheem niaj hnub no.
Raws li cov txheej txheem ntawm kev faib tawm ntuj, txhua tus neeg ntawm ib pab pawg yuav tsum sib koom ua poj koob yawm txwv. Yog li, qhov system no yog siv los kwv yees cov yam ntxwv sib koom los ntawm cov kab mob hauv pawg. Qhov tsis zoo ntawm cov txheej txheem ntawm kev faib tawm no yog qhov tsis siv los faib tuaj yeem hloov pauv sai thiab tsim cov ntaub ntawv tshiab. Qhov no tuaj yeem ua rau muaj kev tsis sib haum xeeb hauv pawg.
Phylogenetic System of Classification yog dab tsi?
Phylogenetic kev faib tawm yog ib qho kev faib tawm uas siv los faib cov kab mob raws li cov noob caj noob ces. Yog li ntawd, nws yog raws li evolutionary caj ces. Cov kab ke no ua haujlwm ntawm txoj kev xav uas cov kab mob uas qhia txog qib siab ntawm homology hauv lawv cov DNA tau suav tias muaj kev cuam tshuam ntau dua. Cov txheej txheem no yog ua raws li kev hloov pauv ntawm lub neej. Phylogenetic classification system depicts genetic kev sib raug zoo ntawm cov kab mob los ntawm tsob ntoo daim duab hu ua cladograms.

Cladograms muaj cov kab mob uas suav nrog cov poj koob yawm txwv hom nrog rau nws cov xeeb ntxwv. Phylogenetic classification system yog cov txheej txheem niaj hnub ntawm kev faib cov kab mob. Kev txhim kho hauv molecular biology thiab kev tshuaj xyuas cov txheej txheem cuam tshuam nrog DNA coj mus rau kev txhim kho cov kev faib tawm kom ntseeg tau ntau dua rau cov kab mob.
Dab tsi yog qhov zoo sib xws ntawm Artificial Natural thiab Phylogenetic System of Classification?
- Txhua peb hom yog cov txheej txheem ntawm kev faib khoom siv los faib cov kab mob.
- Cov kab ke no ua haujlwm ntawm lub platform sib xws.
- Txhua peb hom tseem siv nrog ntau zaus.
Dab tsi yog qhov txawv ntawm Artificial Natural thiab Phylogenetic System of Classification?
Qhov kev faib tawm dag zog suav nrog kev xaiv cov kab mob arbitrarily thiab pab pawg raws li. Nws ruaj khov thiab yooj yim rau kev txhim kho tab sis tsis qhia txog kev sib raug zoo evolutionary. Txawm li cas los xij, cov txheej txheem kev faib tawm ntuj yog raws li kev sib raug zoo evolutionary. Meanwhile, phylogenetic kev faib tawm yog ib qho kev faib tawm uas siv los faib cov kab mob raws li cov noob caj noob ces. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm cov khoom tsim ntuj tsim thiab phylogenetic system ntawm kev faib tawm.
Cov hauv qab no infographic nthuav tawm qhov sib txawv ntawm cov khoom tsim ntuj tsim thiab phylogenetic system ntawm kev faib tawm hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Artificial vs Natural vs Phylogenetic System of Classification
Kev faib cov kab mob yog ib qho tseem ceeb ntawm cov txheej txheem ntawm evolution. Thawj hom kev faib tawm tsim nyob rau hauv keeb kwm ntawm kev faib tawm yog kev faib tawm dag zog. Nws yog ib qho system ntawm kev faib tawm raws li cov yam ntxwv uas tsis yog evolutionary xaiv arbitrarily thiab pab pawg raws li. Artificial classification yog ruaj khov thiab yooj yim rau kev txhim kho tab sis tsis qhia txog kev sib raug zoo evolutionary. Kev faib tawm ntuj yog ib hom kev faib tawm uas siv los faib cov kab mob raws li qhov zoo sib xws thaum xub thawj thiab tom qab ntawd txheeb xyuas lawv cov yam ntxwv sib koom. Kev faib tawm phylogenetic yog ib qho kev faib tawm uas siv los faib cov kab mob raws li cov noob caj noob ces. Yog li, qhov no qhia txog qhov sib txawv ntawm cov khoom tsim ntuj tsim thiab cov txheej txheem phyogentic ntawm kev faib tawm.
