Cov ntaub ntawv pov thawj rau evolution los ntawm ntau yam sib txawv 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.
Kuj kom paub yog, plaub pawg loj ntawm cov pov thawj rau kev hloov pauv yog dab tsi?
Dab tsi yog Plaub Hom Ntawv Pov Thawj rau Evolution
- Homologus Organs:
- Lub cev vestigial:
- Fossil Evidences:
- Petrification:
- Archeopteryx:
- Txuas txuas:
Dhau li saum toj no, dab tsi yog qhov chaw pov thawj rau evolution? Tsib hom pov thawj rau evolution tau tham nyob rau hauv nqe lus no: cov kab mob thaum ub tseem nyob, cov pob txha pob txha, qhov zoo sib xws ntawm cov kab mob uas muaj sia nyob niaj hnub no, qhov zoo sib xws hauv DNA, thiab qhov zoo sib xws ntawm embryos.
Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov txawv theories ntawm evolution?
- biologist. Noun. tus kws tshawb fawb uas kawm txog cov kab mob nyob.
- evolution. Noun. hloov nyob rau hauv cov cuab yeej cuab tam ntawm cov pej xeem nyob rau lub sij hawm.
- genetic drift. Noun. random variations nyob rau hauv lub zaus ntawm cov noob nyob rau hauv cov pejxeem, tshwj xeeb tshaj yog cov neeg me.
- kev xav. Noun.
- natural xaiv. Noun.
- kab mob. Noun.

Dab tsi yog rau daim ntawv pov thawj rau evolution?
Cov ntsiab lus hauv cov teeb no (7)
- fossil ntaub ntawv. zoo li, duab, loj, qhov twg los yog li cas lawv nyob, lub sij hawm lub sij hawm lawv nyob rau hauv, dab tsi lwm yam kab mob lawv nyob nrog.
- homologous qauv.
- pov thawj embryological.
- biochemical pov thawj.
- thaj chaw faib khoom.
- cov qauv vestigial.
- txoj cai ntawm succession.

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 yog qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab qhov sib txawv ntawm qhov ntab?
Integers thiab floats yog ob yam sib txawv ntawm cov ntaub ntawv tus lej. Ib tus lej (feem ntau hu ua anint) yog tus lej tsis muaj tus lej lej. Float isa floating-point number, uas txhais tau hais tias nws yog tus lej uas muaj tus lej lej. Floats siv thaum xav tau ntau dua
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
Qhov twg ntawm 1905 cov ntaub ntawv tau muab thawj qhov pov thawj zoo rau lub neej ntawm atom?
Annus mirabilis cov ntaub ntawv
Cov pov thawj ntawm cov organic evolution yog dab tsi?
Cov pov thawj txhawb nqa Organic Evolution: Cov pov thawj los ntawm Palaeontology. Cov ntaub ntawv pov thawj los ntawm Comparative Morphology. Cov ntaub ntawv pov thawj los ntawm Taxonomy. Cov pov thawj los ntawm Comparative Physiology thiab Biochemistry. Cov ntaub ntawv pov thawj los ntawm Embryology-Cov Lus Qhuab Qhia ntawm Recapitulation lossis Biogenetic Laws. Cov ntaub ntawv pov thawj los ntawm Biogeography (Kev faib tawm ntawm cov kab mob hauv qhov chaw)
