Divergent evolution tshwm sim thaum ob hom sib cais evolve txawv ntawm ib tug poj koob yawm txwv. Speciation yog los ntawm sib txawv evolution thiab tshwm sim thaum ib hom diverges mus rau ntau hom xeeb leej xeeb ntxwv. Darwin's finches yog ib qho piv txwv ntawm qhov no.

Yog li, hom kev hloov pauv hloov pauv dab tsi feem ntau pom ntawm cov Islands tuaj?

Tshooj 7 (Evolution) Cov Lus Txhais - Lub caij nplooj zeeg 2018

A B
Tsim ib hom tshiab los ntawm cov txheej txheem ntawm divergent evolution Qhov tshwj xeeb
Kev sib txawv sai sai thiab speciation los ntawm ib tug poj koob yawm txwv feem ntau pom ntawm cov Islands tuaj Kev hloov hluav taws xob
Kev tsim ntawm ib hom tshiab los ntawm kev cais thaj chaw Allopatric speciation

Ob hom twg zoo sib xws tab sis muaj kev hloov pauv hloov pauv? Ob hom uas yog heev zoo sib xws thiab tau undergone divergent evolution yog cov khoom siv hma (Vulpes macrotis) thiab Arctic hma liab (Vulpes lagopus).

Ua raws li qhov no hauv kev xav, dab tsi yog qhov piv txwv ntawm kev hloov pauv txawv txawv?

Divergent evolution tshwm sim thaum cov tsiaj muaj feem xyuam nrog tsim cov yam ntxwv tshwj xeeb vim muaj qhov sib txawv ntawm ib puag ncig lossis kev xaiv xaiv. Ib qho classic piv txwv ntawm divergent evolution yog Galapagos finch uas Darwin pom tias nyob rau hauv ib puag ncig sib txawv, cov finches 'beaks yoog txawv.

Dab tsi yog lwm lub npe rau kev hloov pauv hloov pauv?

Divergent evolution los yog sib txawv kev xaiv yog sib sau ua ke ntawm qhov sib txawv ntawm cov neeg muaj feem xyuam nrog nyob rau hauv ib hom, ua rau speciation.
