Phylogenetic classification system yog raws li evolutionary poj koob yawm txwv. Nws tsim cov ntoo hu ua cladograms, uas yog pawg ntawm cov kab mob uas suav nrog cov poj koob yawm txwv hom thiab nws cov xeeb ntxwv. Kev faib tawm kab mob nyob rau hauv lub hauv paus ntawm qhovntsej thiaj tsis mob los ntawm ib tug poj yawm txwv koob yog hu ua phylogenetic kev faib tawm.
Khaws qhov no rau hauv kev xav, leej twg nrhiav tau phylogenetic system ntawm kev faib tawm?
John Hutchinson
Dab tsi yog ob qhov zoo ntawm kev faib tawm phylogenetic? Phylogogenetic kev faib tawm muaj ob lub ntsiab qhov zoo ntawm Linnaean system. Ua ntej, phylogenetic kev faib tawm qhia koj ib yam tseem ceeb txog lub cev: nws cov keeb kwm evolutionary. Thib ob, phylogenetic kev faib tawm tsis sim "rank" kab mob.
Nyob rau hauv txoj kev no, dab tsi yog qhov txawv ntawm ntuj thiab phylogenetic system ntawm kev faib tawm?
yog dab tsi Qhov sib txawv ntawm ntuj thiab phylogenetic system ntawm kev faib tawm . Natural system ntawm kev faib tawm yog ua raws li cov cim tseem ceeb xws li morphology, thiab lwm yam. Phylogogenetic system ntawm kev faib tawm yog raws li keeb kwm evolutionary ntawm cov kab mob.
Qhov xwm txheej phylogenetic yog dab tsi?
lo?d??ˈn?t?ks, -l?-/ (Greek: φυλή, φ?λον – phylé, phylon = pawg, xeem, haiv neeg + γενετικός – genetikós = origin, source, birth) evolutionary keeb kwm thiab kev sib raug zoo ntawm cov tib neeg los yog pab pawg neeg ntawm cov kab mob (xws li hom, los yog pejxeem).

Dab tsi yog 2 kev faib tawm ntawm kev sib xyaw?
Thaum ob lossis ntau yam khoom sib xyaw ua ke, qhov tshwm sim yog hu ua kev sib tov. Kev sib xyaw tuaj yeem muab faib ua ob pawg loj: homogeneous thiab heterogeneous. Ib homogeneous sib tov yog ib qho uas muaj cov ntsiab lus ntawm nws cov khoom sib xyaw ua ke thoob plaws
Linnaean system ntawm kev faib tawm yog dab tsi?
Lub Linnaean system ntawm kev faib tawm muaj cov hierarchy ntawm pawg, hu ua taxa (singular, taxon). Taxa ntau ntawm lub nceeg vaj mus rau hom (saib daim duab hauv qab). Lub nceeg vaj yog pawg loj tshaj plaws thiab muaj kev sib koom ua ke. Nws muaj cov kab mob uas sib koom tsuas yog ob peb yam sib xws
Dab tsi yog keeb kwm ntawm kev faib tawm?
Niaj hnub nimno taxonomic system yog tsim los ntawm Swedish botanist Carolus Linnaeus (1707-1778). Nws siv cov yam ntxwv ntawm lub cev yooj yim ntawm cov kab mob los txheeb xyuas thiab sib txawv ntawm cov tsiaj sib txawv thiab yog raws li cov noob caj noob ces. Linnaeus tau tsim ib lub hierarchy ntawm pawg rau taxonomy
Qhov kev txiav txim ntawm qhov kev faib tawm yog dab tsi?
Muaj xya theem loj ntawm kev faib tawm: Kingdom, Phylum, Class, Order, Family, Genus, thiab Hom
Dab tsi yog theem ntawm Linnaean system ntawm kev faib tawm?
Niaj hnub nimno taxonomic classification system muaj yim theem tseem ceeb (los ntawm feem ntau suav nrog rau feem ntau tshwj xeeb): Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species Identifier
