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.
