Classically, speciation tau raug pom raws li txheej txheem peb-theem: Kev cais cov pejxeem Divergence nyob rau hauv cov yam ntxwv ntawm cov pej xeem sib cais (piv txwv li mating system los yog chaw nyob siv). Kev sib cais ntawm cov pej xeem uas tswj kev sib cais thaum cov pej xeem tuaj ntsib dua (kev sib cuag thib ob).

4 kauj ruam rau speciation yog dab tsi?

Speciation tuaj yeem txhais tau tias:

  • kev tsim ntawm hom tshiab;
  • kev sib cais ntawm kab mob phylogenetic;
  • nrhiav tau ntawm kev sib cais ntawm kev sib cais ntawm cov txheej txheem tsim tawm kev tsis sib xws ntawm cov pejxeem;
  • txheej txheem uas ib hom cais ua 2 lossis ntau hom.

4 yog vim li cas qhov tshwj xeeb?

Cov kws tshawb fawb xav tias thaj chaw nyob ib leeg yog ib txoj hauv kev rau cov txheej txheem ntawm speciation pib: dej hloov cov chav kawm, roob nce siab, cov teb chaws drift, kab mob tsiv teb tsaws, thiab dab tsi yog ib zaug cov pej xeem txuas ntxiv tau muab faib ua ob los yog ntau dua cov neeg tsawg.

thawj kauj ruam hauv kev tshwj xeeb yog dab tsi?

-- thawj kauj ruam ntawm tus txheej txheem yog thaj chaw sib cais ntawm ob haiv neeg ntawm tib hom. - qhov tshwm sim: nws tshem tawm qhov txav ntawm cov noob ntawm ob pawg neeg. tso cai rau ob tug pej xeem hloov zuj zus ntawm ib leeg.

Yuav ua li cas yog cov kauj ruam ntawm speciation?

Classically, speciation tau raug pom raws li tus txheej txheem peb-theem:

  • Kev cais cov pejxeem.
  • Kev sib txawv ntawm cov neeg sib cais (piv txwv li kev sib koom ua ke lossis kev siv vaj tse).
  • Kev sib cais ntawm cov pejxeem uas tswj kev cais tawm thaum cov pejxeem rov sib cuag dua (kev sib cuag thib ob).
