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.

Puas yog sib npaug thiab sib npaug?
yog qhov sib npaug yog qhov xwm txheej ntawm qhov kev sib tw uas muaj kev sib tw sib npaug, ua rau tsis muaj qhov hloov pauv thaum sib npaug yog ib lub zog sib npaug, tab sis ntxeev ntawm, qhov tshwm sim sum ntawm vector zog; lub zog uas sib npaug rau lwm lub zog, yog li nqa ib qho khoom mus rau qhov sib npaug.
Puas muaj qhov sib npaug sib npaug?
Ib kab kab sib npaug feem ntau muaj ib qho kev daws teeb meem, tab sis qee zaum nws tsis tuaj yeem muaj kev daws teeb meem (kab kab sib txuas) lossis kev daws tsis kawg (ib kab). Kab lus no tshuaj xyuas tag nrho peb qhov xwm txheej. Ib qho kev daws teeb meem.
Puas yog txhua qhov sib npaug sib npaug?
Yog, tag nrho peb tiam ntawm daim ntawv dawb tau raws nraim qhov loj me nrog tib lub pob layout. Siv tau rau rooj plaub raws li cov ntaub ntawv paperwhite haum rau txhua daim ntawv dawb, yav dhau los thiab tam sim no. Qhov ntsuas 6 nti yog hais txog qhov loj me ntawm lub vijtsam nkaus xwb, ntsuas ntawm kab pheeb ces kaum ntawm ib ces kaum mus rau lub kaum sab xis.
Leej twg yog tus sib npaug thiab sib npaug?
Yog li ntawd, yog tias tag nrho cov sab ntawm lub polygon yog tib qhov ntev, lub polygon tau hais tias sib npaug, thaum tag nrho cov kaum sab hauv ntawm lub polygon yog qhov sib npaug. tib qhov kev ntsuas, tus polygon tau hais tias yog equiangular.
Dab tsi yog qhov sib npaug sib npaug?
Revolving credit yog hom credit uas tsis muaj tus lej them nyiaj tas li, sib piv rau cov credit qiv. Cov npav rho nyiaj yog ib qho piv txwv ntawm kev siv cov credit siv los ntawm cov neeg siv khoom. Cov tuam txhab qiv nyiaj rov qab feem ntau yog siv los muab cov nyiaj tau los rau lub tuam txhab kev ua haujlwm txhua hnub.
