Cov kws tshawb fawb xav tias hom tsiaj uas muaj kev hloov pauv luv dua tau hloov zuj zus feem ntau los ntawm kev sib npaug, thiab cov nrog kev hloov pauv ntev dua feem ntau hloov zuj zus los ntawm gradualism. Gradualism yog kev xaiv thiab kev hloov pauv uas tshwm sim maj mam. Lub sijhawm luv luv nws tsis yooj yim pom.
Yuav ua li cas sau ntawv equilibrium cuam tshuam rau gradualism?
Rau Gradualism, kev hloov pauv hauv hom qeeb thiab maj mam, tshwm sim me me nyob rau lub sijhawm hloov pauv hauv cov noob caj noob ces, whereas rau Punctuated Equilibrium, evolution tshwm sim nyob rau hauv spurts ntawm kuj ceev hloov nrog lub sij hawm ntev ntawm tsis- change.
Yam gradualism thiab punctuated equilibrium zoo sib xws li cas?
Ob leeg gradualism thiab punctuated equilibrium piav qhia tus nqi ntawm speciation. Rau Gradualism, kev hloov pauv hauv cov tsiaj yog qeeb thiab maj mam, tshwm sim nyob rau hauv me me lub sij hawm hloov nyob rau hauv lub gene pas dej ua ke, whereas rau Punctuated Equilibrium, evolution tshwm sim nyob rau hauv spurts ntawm kuj ceev hloov nrog lub sij hawm ntev tsis hloov [1].
Puas yog sau ntawv sib npaug thiab gradualism sib koom ua ke?
Kev hloov pauv ntawm Globoconella clade qhia ob qho tib si phyletic gradualism thiab cim qhov sib npaug. Ob qho "lwm yam" evolutionary qauv no ntxiv ib leeg es tsis yog kev sib koom ua ke. Ob tus qauv yog qhov tseem ceeb ntawm kev muab cov duab tiav ntawm kev hloov pauv ntawm Globoconella.
Puas muaj pov thawj rau kev sib npaug?
Pov thawjrau qhov sib npaug ntawm cov lus dag hauv cov caj ces ntawm ntau yam kab mob, raws li kev tshawb fawb hauv lub lim tiam no Science. Cov kws tshawb fawb tau tshaj tawm tias kwv yees li ib feem peb ntawm cov ntoo phylogenetic reconstructed ntawm tsiaj, nroj tsuag, thiab fungi qhia lub sij hawm ntawm ceev molecular evolution.
