Biogeography, kev kawm txog thaj chaw faib khoom ntawm cov kab mob, muab cov ntaub ntawv qhia txog yuav ua li cas thiab thaum twg tsiaj yuav hloov zuj zus. Fossils muab pov thawj ntawm kev hloov pauv mus sij hawm ntev, sau tseg yav dhau los ntawm cov tsiaj uas tam sim no ploj mus.

biogeography txhawb txoj kev xav ntawm evolution li cas?

Biogeography yog kawm txog yuav ua li cas thiab yog vim li cas cov nroj tsuag thiab tsiaj nyob qhov twg lawv ua. … Dav dav, txoj kev xav ntawm evolution tau txhawb nqa los ntawm biogeography los ntawm cov pov thawj xws li hom tsiaj hauv ntiaj teb tau muab faib thoob ntiaj teb raws li lawv cov caj ces kev sib raug zoo rau ib leeg Nws kuj muab pov thawj rau evolution.

Cov piv txwv ntawm biogeography txhawb kev hloov pauv yog dab tsi?

Island Biogeography

Lub biogeography ntawm islands yields ib co ntawm cov pov thawj zoo tshaj plaws rau evolution. Xav txog cov noog hu ua finches uas Darwin tau kawm ntawm Galápagos Islands (saib daim duab hauv qab). Tag nrho cov finches tej zaum nqis los ntawm ib tug noog uas tuaj txog ntawm cov Islands tuaj ntawm South America.
