Kev kawm ntawm ib hom ntawm pov thawj ntawm evolution hu ua embryology , kev kawm ntawm embryos. Ntau yam zoo ntawm ib hom tsiaj tshwm sim hauv embryo ntawm lwm hom tsiaj. Piv txwv li, ntses embryos thiab tib neeg embryos ob leeg muaj gill slits. Nyob rau hauv cov ntses lawv loj hlob mus rau hauv gills, tab sis nyob rau hauv tib neeg lawv ploj ua ntej yug.

Yog li ntawd, Embryology muab pov thawj li cas rau evolution?

Embryology , kev kawm txog kev txhim kho ntawm lub cev ntawm lub cev mus rau nws cov neeg laus, muab pov thawj rau evolution Raws li embryo tsim nyob rau hauv dav-divergent pawg ntawm cov kab mob yuav tsum tau khaws cia. Lwm daim ntawv ntawm pov thawj ntawm evolution yog convergence ntawm daim ntawv nyob rau hauv cov kab mob uas sib koom ib puag ncig zoo sib xws.

Tom qab ntawd, lo lus nug yog, kev loj hlob embryonic puas tuaj yeem siv los ua pov thawj rau evolution? Yog, nrog cov embryo muaj cov qauv zoo sib xws, koj ua tau infer hais tias nyob rau hauv qee kis, txawm tias qhov txawv ntawm cov yam ntxwv ntawm cov kab mob nyob, muaj ua tau ua piv txwv tias qhov no embryonic kev loj hlob tuaj yeem ua ib pov thawj ntawm evolution.

Tsis tas li ntawd, biogeography pov thawj ntawm evolution li cas?

Biogeography , kev kawm txog thaj chaw faib khoom nruab nrog cev, muab cov ntaub ntawv hais txog yuav ua li cas thiab thaum twg cov tsiaj muaj hloov zuj zus . Fossils muab pov thawj ntawm lub sij hawm ntev evolutionary kev hloov, sau tseg yav dhau los muaj nyob ntawm hom uas tam sim no ploj mus.

Kev sib piv embryology yog dab tsi thiab nws txhawb nqa evolution li cas?

Teb ntawm kev sib piv embryology Lub hom phiaj kom nkag siab tias embryos txhim kho li cas, thiab tshawb fawb txog kev sib cuam tshuam ntawm cov tsiaj. Nws tau txhawb nqa evolutionary txoj kev xav los ntawm kev ua kom pom tias txhua tus vertebrates txhim kho zoo ib yam thiab muaj cov poj koob yawm txwv zoo sib xws.

Pom zoo:

Dab tsi yog qhov txawv ntawm cov pov thawj rau evolution?

Cov pov thawj rau evolution los ntawm ntau qhov chaw ntawm biology: Anatomy. Cov tsiaj txhu tuaj yeem sib koom ua ke ntawm lub cev zoo sib xws vim tias qhov tshwj xeeb muaj nyob rau hauv ib qho qub poj koob yawm txwv (homologous qauv). Molecular biology. DNA thiab cov noob caj noob ces cuam tshuam txog kev sib koom caj ces ntawm lub neej. Biogeography. Fossils. Kev soj ntsuam ncaj qha

Koj ua pov thawj li cas cov kab yog sib npaug hauv cov ntawv pov thawj?

Thawj yog yog tias cov ces kaum sib thooj, cov ces kaum uas nyob rau tib lub ces kaum ntawm txhua qhov kev sib tshuam, sib npaug, ces cov kab sib npaug. Qhov thib ob yog yog tias qhov sib txawv sab hauv lub kaum sab xis, cov ces kaum uas nyob rau sab nraud ntawm lub transversal thiab sab hauv cov kab sib npaug, sib npaug, ces cov kab sib npaug

Dab tsi pov thawj siv cov duab ntawm lub dav hlau sib koom ua pov thawj cov khoom geometric?

Cov ntaub ntawv pov thawj uas siv cov duab ntawm lub dav hlau sib koom ua pov thawj geometric zog yog hu ua trigonometric

Yuav ua li cas sib piv embryology muab pov thawj rau evolution?

Pov thawj rau Evolution: Sib piv embryology yog ib qho ntawm cov kab tseem ceeb ntawm cov pov thawj hauv kev txhawb nqa ntawm evolution. Hauv kev sib piv embryology, lub cev ntawm embryos los ntawm ntau hom sib piv los ntawm kev loj hlob ntawm embryos. Qhov zoo sib xws ntawm cov tsiaj sib txawv qhia tias peb txhua tus tuaj ntawm ib tug poj koob yawm txwv
