Qhov sib txawv tseem ceeb ntawm taxonomy thiab systematics yog taxonomy yog kev qhuab qhia ntawm kev faib cov kab mob mus rau hauv taxa los ntawm kev npaj lawv raws li kev txiav txim siab thaum systematics yog qhov dav ntawm biology uas kawm txog kev sib txawv ntawm hom.
Taxonomy thiab systematics yog cov kev qhuab qhia zoo sib xws hauv biology. Txawm li cas los xij, muaj qhov sib txawv nthuav dav ntawm taxonomy thiab systematics. Vim tias qhov zoo sib xws ntawm ob qho no, ntau tus ntawm peb xav tias cov no yuav muaj cov ntsiab lus zoo sib xws. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum tau kawm ob qho kev qhuab qhia zoo kom nkag siab qhov sib txawv ntawm kev sau se thiab cov txheej txheem vim peb coob leej, suav nrog cov kws paub txog biologists, tej zaum hauv qee qhov tsis meej pem.
Taxonomy yog dab tsi?
Taxonomy yog kev qhuab qhia ntawm kev faib cov kab mob mus rau hauv taxa los ntawm kev npaj lawv hauv kev txiav txim siab heev. Taxonomists yog cov neeg tshawb fawb uas ua haujlwm hauv daim teb no. Lawv ua lub npe ntawm taxa nyob rau hauv ib tug hierarchical yam: Kingdom, Phylum, Class, Order, Family, Genus, Hom, thiab lwm yam taxonomic theem. Kev saib xyuas ntawm kev sau cov qauv yog ib qho ntawm ntau lub luag haujlwm uas tus kws sau se yuav ua. Li no, taxonomy muab cov cim qhia txog kev kawm cov qauv tshiab. Tsis tas li ntawd, kev faib tawm ntawm qee hom yog qhov tseem ceeb heev rau kev ciaj sia ntawm lwm yam kab mob; yog li ntawd taxonomy ncaj qha koom nrog kev kawm txog qhov ntawd thiab. Ib qho ntawm cov haujlwm paub zoo uas cov kws sau paj lug ua yog lub npe ntawm cov kab mob raws li binomial nomenclature: ib lub npe dav dav thiab tshwj xeeb. Qee lub sij hawm, lawv kuj suav nrog cov npe sub-npe kom paub meej.
Taxonomists piav txog cov kab mob, ob qho tib si thiab cov tsiaj uas ploj mus los ntawm kev tshawb fawb. Txij li thaum ib puag ncig hloov pauv txhua lub sijhawm, cov tsiaj yuav tsum yoog raws, thiab qhov tshwm sim no tshwm sim sai ntawm cov kab; taxonomical yam tseem ceeb heev uas yuav tsum tau hloov kho rau tej pab pawg neeg ntawm cov kab mob raws li cov lus piav qhia rau ib yam tsiaj tau hloov nyob rau hauv ib tug me me lub sij hawm. Yog li ntawd, lub npe kuj tseem yuav raug hloov nrog cov lus piav qhia tshiab ua tus taxon tshiab. Qhov tseeb, taxonomy yog ib thaj chaw zoo nkauj hauv biology nrog kev koom tes ntawm cov kws tshawb fawb muaj siab heev uas tau mob siab rau kev qhuab qhia thiab feem ntau dhau los ntawm ntau yam kev nyuaj siab hauv cov tsiaj qus.
Dab tsi yog Systematic?
Systematics lossis biological systematics yog qhov dav ntawm biology uas kawm txog kev sib txawv ntawm hom. Systematics txiav txim siab ob qho tib si uas tseem tshuav thiab ploj lawm thiab tseem txiav txim siab txog kev sib raug zoo ntawm cov tsiaj. Tsis tas li ntawd, nws tswj hwm cov kev coj ua ntawm taxonomy nrog rau npe, piav qhia, txheeb xyuas, thiab cov qauv khaws cia ntawm hom. Tsis tas li ntawd, qhov kev qhuab qhia no kawm txog keeb kwm kev hloov pauv thiab kev hloov pauv ib puag ncig ntawm hom.
Kev tsim cov ntoo evolutionary - phylogenetic ntoo lossis cladograms - yog ib lub hom phiaj tseem ceeb ntawm kev ua haujlwm. Ua ntej tsim cov ntoo evolutionary, cov kws tshawb fawb tau tshawb xyuas keeb kwm ntawm ib pawg ntawm hom thiab lawv txheeb xyuas cov ntaub ntawv khaws tseg xws li cov yam ntxwv ntawm lub cev thiab cov molecular thiab kev sib raug zoo nrog cov xwm txheej ib puag ncig, thiab lwm yam.
Systematics tseem ceeb heev rau naming prehistoric lossis extinct hom. Yog li ntawd, lub ntsiab cuab yeej ntawm ib tug systematist yog lub taxonomy. Ib qho ntawm cov kev siv tseem ceeb ntawm kev ua haujlwm yog tias nws yog qhov qhia txog biodiversity ntawm lub ntiaj teb, uas tuaj yeem siv los npaj cov keeb kwm yav dhau los khaws cia cov tsiaj muaj sia.
Dab tsi yog qhov zoo sib xws ntawm Taxonomy thiab Systematics?
- Taxonomy thiab systematics yog ob txoj kev qhuab qhia ntawm biology.
- Nyob rau hauv ob qho tib si, ob qho tib si thiab cov tsiaj ploj tuag tau ua tib zoo kawm.
- Cov kev tshawb fawb no yog qhov tseem ceeb txhawm rau tiv thaiv cov kab mob uas muaj kev phom sij.
- Tsis tas li, lawv tseem ceeb los txheeb xyuas hom tshiab thiab lawv txoj kev sib raug zoo.
Qhov txawv ntawm Taxonomy thiab Systematics yog dab tsi?
Taxonomy yog qhov tseem ceeb rau lub npe, piav qhia, npaj, thiab txheeb xyuas qee hom, qhov systematics tseem ceeb los muab kev teeb tsa rau tag nrho cov haujlwm taxonomic. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm taxonomy thiab systematics. Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm taxonomy thiab systematics yog qhov evolutionary keeb kwm ntawm hom yog kawm nyob rau hauv systematics, tab sis tsis nyob rau hauv taxonomy.
Tsis tas li ntawd, ib puag ncig muaj feem cuam tshuam ncaj qha rau kev txheeb xyuas cov txheej txheem, qhov ntawd tsis ncaj qha cuam tshuam nrog kev sau se. Ntxiv mus, taxonomy yuav hloov nrog lub sij hawm, whereas systematics yuav tsum tsis txhob hloov yog hais tias qhov kev tshawb fawb tau ua kom raug. Yog li ntawd, peb tuaj yeem txiav txim siab qhov no ib yam li qhov sib txawv ntawm kev sau se thiab cov txheej txheem.
Summary – Taxonomy vs Systematic
Systematics yog thaj chaw loj dua li kev sau se. Qhov tseeb, taxonomy yog ib ceg ntawm systematics. Taxonomy yog ib thaj chaw ntawm biology uas ua rau kev faib thiab npe ntawm cov kab mob. Ntawm qhov tod tes, systematics yog ib thaj chaw ntawm biology uas txiav txim siab txog kev sib raug zoo ntawm cov kab mob. Taxonomy yog qhov cuab yeej tseem ceeb hauv kev ua haujlwm. Qhov tseem ceeb tshaj plaws, taxonomy tsis cuam tshuam nrog keeb kwm evolutionary ntawm cov kab mob thaum systematics cuam tshuam nrog cov keeb kwm evolutionary ntawm cov kab mob. Yog li, qhov no qhia txog qhov sib txawv ntawm taxonomy thiab systematics.
