Ib phylogeny, lossis evolutionary tsob ntoo, sawv cev kev sib raug zoo ntawm cov kab mob los yog pab pawg ntawm cov kab mob, hu ua taxa (singular: taxon). Cov lus qhia ntawm tsob ntoo sawv cev rau pawg ntawm cov xeeb leej xeeb ntxwv (feem ntau hom) thiab cov kab ntawm tsob ntoo sawv cev rau cov poj koob yawm txwv ntawm cov xeeb leej xeeb ntxwv.
tsob ntoo phylogenetic qhia li cas?
Ib tsob ntoo phylogenetic, tseem hu ua phylogeny, yog daim duab uas depicts cov kab ntawm evolutionary qhovntsej thiaj tsis mob ntawm ntau hom, kab mob, los yog noob los ntawm ib tug poj koob yawm txwv.
tsob ntoo phylogenetic tsim li cas?
Ib tsob ntoo phylogenetic yuav tsim tau siv morphological (lub cev zoo), biochemical, cwj pwm, los yog molecular yam ntxwv ntawm hom lossis lwm pab pawgHauv kev tsim ib tsob ntoo, peb npaj cov hom rau hauv pawg nested raws li kev sib koom derived traits (cov yam ntxwv txawv ntawm cov pab pawg neeg poj koob yawm txwv).
Koj nyeem tsob ntoo phylogenetic hauv biology li cas?
cag tsob ntoo sawv cev rau cov xeeb leej xeeb ntxwv, thiab cov lus qhia ntawm cov ceg sawv cev ntawm cov xeeb leej xeeb ntxwv ntawd. Thaum koj txav ntawm lub hauv paus mus rau cov lus qhia, koj tab tom mus tom ntej hauv lub sijhawm. Thaum ib tug kab mob sib cais (speciation), nws yog sawv cev raws li branching ntawm ib tug phylogeny.
tsob ntoo phylogenetic txhawb kev hloov pauv li cas?
Ib tsob ntoo phylogenetic tuaj yeem pab taug ib hom rov qab los ntawm keeb kwm evolutionary, nqes cov ceg ntoo, thiab nrhiav lawv cov xeeb leej xeeb ntxwv ntawm txoj kev. Sij hawm dhau mus, ib caj ces yuav khaws tau qee yam ntawm lawv cov poj koob yawm txwv tab sis kuj tseem yuav raug hloov kho kom haum rau qhov chaw hloov pauv.

Pine ntoo puas yog tsob ntoo txiv ntoo?
Pine ntoo rov tsim dua los ntawm kev tsim cov noob Tsis zoo li cov ntoo deciduous, uas tsim cov noob uas nyob ib puag ncig los ntawm cov txiv hmab txiv ntoo, cov ntoo ntoo yog nyob ntawm cov nplai ntawm cov qauv hu ua cones (pine cones). Pine ntoo muaj ob qho tib si txiv neej thiab poj niam cov qauv kev loj hlob, los yog cones.
Puas yog cashews cog rau ntawm tsob ntoo lossis ib tsob ntoo?
Teb: Cov txiv maj phaub yog ib tsob ntoo tauj thiab subtropical evergreen shrub lossis ntoo. Nws hlob nyob qhov twg cov av yog fertile thiab humidity siab. Cashews yog ib txwm nyob rau thaj tsam Central thiab South America, thiab tam sim no muaj ntau nyob rau sab hnub tuaj Africa thiab Is Nrias teb .
Puas nce tsob ntoo nrog spikes ua rau tsob ntoo?
Thaum cov spikes no siv rau cov ntoo muaj sia, nws yog kev puas tsuaj rau tsob ntoo thiab tsim kev puas tsuaj yam tsis tsim nyog Txhua qhov kev sib tsoo los ntawm kev nce toj nce toj ua rau qee yam ntoo ntoo tuag, tab sis qhov no txawv ntawm tsob ntoo mus rau tsob ntoo.
Puas yog tsob ntoo snowbell yog tsob ntoo ntsuab?
Japanese snowbell ntoo yog deciduous, tab sis lawv tsis tshwj xeeb tshaj yog thaum lub caij nplooj zeeg . Puas yog Japanese Snowbell poob nws nplooj? Lub caij nplooj zeeg xim tsis zoo nkauj, tab sis cov nplooj tig daj mus rau xim liab.
Dab tsi yog tsob ntoo phylogenetic cladogram?
Ib tsob ntoo phylogenetic yog tsob ntoo evolutionary uas qhia txog kev sib raug zoo ntawm cov tsiaj sib txawv Siv. Cladograms muab cov duab hypothetical ntawm qhov tseeb evolutionary keeb kwm ntawm cov kab mob. Phylogenetic ntoo muab qhov tseeb sawv cev ntawm evolutionary keeb kwm ntawm cov kab mob .
