Qhov tseem ceeb sib txawv – Rooted vs Unrooted Phylogenetic Tsob Ntoo
Phylogeny yog ib qho tseem ceeb uas tshawb nrhiav lub neej hauv ntiaj teb mus txog lub sijhawm. Nws qhia txog kev sib txuas ntawm cov kab mob nrog lawv cov poj koob yawm txwv thiab cov xeeb leej xeeb ntxwv. Cov kev sib raug zoo ntawm cov kab mob yog cov duab kos duab los ntawm ntau yam ntoo zoo li cov sawv cev xws li dendogram, cladogram, phenogram, phylogram, thiab lwm yam. Ib tsob ntoo phylogenetic yog ib tsob ntoo zoo li daim duab uas piav qhia txog kev sib raug zoo ntawm cov kab mob nrog cov evolutionary nrug. Muaj ob lub ntsiab ntawm cov ntoo phylogenetic hu ua rooted thiab unrooted. Qhov sib txawv tseem ceeb ntawm tsob ntoo hauv paus thiab unrooted phylogenetic tsob ntoo yog tias tsob ntoo cag pom cov poj koob yawm txwv ntawm tsob ntoo thaum unrooted phylogenetic tsob ntoo tsis qhia cov txiv yawg koob.
Yuav ua li cas cog tsob ntoo Phylogenetic?
Ib tsob ntoo phylogenetic hauv paus ua haujlwm raws li daim duab qhia txog keeb kwm evolutionary. Nws muaj ib tug basal node uas yog hu ua lub hauv paus, sawv cev rau cov poj koob yawm txwv ntawm tag nrho cov pawg ntawm tsob ntoo. Lub hauv paus ntawm tsob ntoo yog suav tias yog qhov qub tshaj plaws ntawm tsob ntoo uas sawv cev rau cov poj koob yawm txwv kawg ntawm txhua pawg uas suav nrog hauv tsob ntoo. Li no, ib tsob ntoo hauv paus qhia tau hais tias cov kev taw qhia ntawm lub sij hawm evolutionary. Los ntawm ib hom ntawm tsob ntoo hauv paus, cov poj koob yawm txwv los yog hom poj koob yawm txwv tuaj yeem pom los ntawm kev taug qab rov qab mus rau basal node. Txij li thaum tsob ntoo hauv paus qhia txog cov kev taw qhia ntawm lub sij hawm evolutionary, nws yog ib qho yooj yim mus nrhiav tau cov laus los yog tshiab pawg nws muaj. Ib tsob ntoo hauv paus tuaj yeem siv los kawm tag nrho cov kab mob. Qhov tseeb rooting ntawm tsob ntoo phylogenetic yog ib qho tseem ceeb thiab tseem ceeb tshaj plaws vim qhov tsis raug hauv paus tuaj yeem ua rau muaj kev txhais tsis raug ntawm kev hloov caj ces ntawm cov kab mob thiab lawv cov kev coj ntawm kev hloov pauv.
Daim duab 01: Ib tsob ntoo muaj zog Phylogenetic
Yuav ua li cas yog tsob ntoo Unrooted Phylogenetic?
Ib tsob ntoo phylogenetic uas tsis muaj hauv paus yog ib daim duab phylogenetic uas tsis muaj cov poj koob yawm txwv zoo ib yam lossis ib lub pob basal. Hom ntoo no tsis qhia txog keeb kwm ntawm evolution ntawm pawg neeg nyiam. Nws tsuas yog piav qhia txog kev sib raug zoo ntawm cov kab mob tsis hais txog cov kev taw qhia ntawm lub sijhawm evolutionary kab. Yog li ntawd, nws yog ib qho nyuaj rau kawm txog evolutionary kev sib raug zoo ntawm cov pab pawg neeg hais txog lub sij hawm siv ib tug unrooted ntoo.
Muaj ob txoj hauv kev tseem ceeb los cag tsob ntoo phylogenetic unrooted. Lawv yog
Nrhiav ib pawg neeg tawm - Qhov no yuav tsum muaj kev paub ua ntej txog kev sib raug zoo ntawm se. Ces ib tug taxon uas nyob sab nraum pab pawg neeg yuav siv tau raws li ib tug outgroup los kos ib cag ntoo phylogenetic
Nrhiav qhov nruab nrab lossis qhov deb - Qhov nruab nrab ntawm qhov deb tshaj plaws ntawm ob lub taxa nyob rau hauv tsob ntoo tuaj yeem suav tias yog lub hauv paus rau tsob ntoo phylogenetic

Summary – Rooted vs Unrooted Phylogenetic Tsob Ntoo
Ib tsob ntoo phylogenetic sawv cev rau txoj hauv kev evolutionary thiab kev sib txuas ntawm cov kab mob uas siv cov duab zoo li tsob ntoo. Phylogenetic tress tuaj yeem tau hauv paus lossis tsis muaj hauv paus. Ib tsob ntoo hauv paus muaj qhov ntawm lub hauv paus, sawv cev rau cov poj koob yawm txwv uas txuas rau txhua pawg neeg nyiam. Ib tsob ntoo unrooted qhia txog kev sib raug zoo ntawm cov kab mob. Txawm li cas los xij, nws tsis piav txog cov poj koob yawm txwv uas txhua pawg sib koom. Qhov no yog qhov txawv ntawm tsob ntoo phylogenetic thiab tsis muaj cag.
