Microevolution vs. Macroevolution . Piv txwv ntawm tej microevolutionary kev hloov pauv yuav suav nrog kev hloov pauv hauv a hom xim lossis loj. Macroevolution Piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav suav tias yog hom tshiab nkaus xwb.
Hauv qhov no, qhov txawv ntawm macroevolution thiab microevolution yog dab tsi?
Microevolution tshwm sim ntawm ib qho me me (hauv ib tus neeg), thaum macroevolution tshwm sim ntawm qhov ntsuas uas hla cov ciam teb ntawm ib hom. Txawm lawv sib txawv , evolution ntawm ob theem no nyob ntawm tib yam, tsim mechanisms ntawm evolutionary hloov: mutation. kev tsiv teb tsaws chaw.
Qhov thib ob, dab tsi yog qee qhov piv txwv ntawm microevolution? Tshuaj tua kab mob, tshuaj tua kab mob, thiab tshuaj tua kab mob yog txhua yam piv txwv ntawm microevolution los ntawm kev xaiv ntuj. Cov enterococci kab mob, qhia ntawm no, tau hloov zuj zus mus rau ntau hom tshuaj tua kab mob.
Ib tug kuj yuav nug, dab tsi yog piv txwv ntawm macroevolution?
Ib hom uas faib ua ob, lossis ib hom uas hloov mus rau lwm hom nyob rau ib lub sijhawm piv txwv ntawm macroevolution . Cov kev hloov pauv no tuaj yeem yog los ntawm kev xaiv hom, kev ywj pheej evolution (tseem hu ua vicariance), keeb kwm txwv lossis kev txwv kev loj hlob.
Ob hom macroevolution yog dab tsi?
MACROEVOLUTION
- Kev tuag coob.
- Kev hloov hluav taws xob.
- Convergent evolution.
- Kev sib hloov.
- Punctuated equilibrium.
- Kev hloov pauv hauv cov noob caj noob ces.

Cov kev hloov ntawm lub cev txawv ntawm cov tshuaj hloov pauv li cas muab ib qho piv txwv ntawm txhua tus?
Kev hloov tshuaj lom neeg tshwm sim los ntawm cov tshuaj tiv thaiv tshuaj, thaum lub cev hloov pauv yog thaum cov teeb meem hloov pauv tab sis tsis yog tshuaj lom neeg. Piv txwv ntawm kev hloov tshuaj lom neeg yog hlawv, ua noj, xeb, thiab rotting. Piv txwv ntawm kev hloov lub cev yog boiling, melting, khov, thiab shredding
