Qhov txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab kev xaiv ntuj yog qhov tshwj xeeb sorting lim cov genotypes raws li tus nqi dispersal thaum lub ntuj xaiv lim cov genotypes raws li kev loj hlob tus nqi.
Cov cwj pwm hloov zuj zus mus rau ntau tiam neeg, pab txhawb kev ciaj sia thiab kev tsim tawm ntawm cov kab mob. Natural xaiv yog lub hauv paus mechanism ntawm evolution. Spatial sorting kuj yog ib qho kev hloov pauv tseem ceeb. Spatial sorting ua haujlwm los ntawm qhov chaw, thaum xaiv ntuj ua haujlwm dhau sijhawm.
Spatial Sorting yog dab tsi?
Spatial sorting yog ib lub tswv yim ntawm kev hloov pauv uas lim cov genotypes raws li kev faib tawm. Yog li ntawd, nws ua haujlwm los lim cov genotypes los ntawm qhov chaw. Cov cwj pwm los yog cov noob muaj feem xyuam rau kev sib cais yog qhov kev txhawj xeeb tseem ceeb hauv qhov tshwm sim no. Kev vam meej ntawm kev tawg lossis tus nqi ntawm cov kab mob dispersal nyob ntawm ntau yam xws li kev ceev, kev ua siab ntev, thiab kev txav mus los. Cov kab mob uas muaj peev xwm ntawm kev tawg sai sai yuav yug me nyuam ua ntej cov tib neeg uas tawg qeeb. Yog li ntawd, cov evolving pejxeem muaj ntau ceev dispersing xeeb tub. Cov tiam neeg vam meej hloov zuj zus sai dua thiab nrawm dua los ntawm qhov sib txawv ntawm qhov zoo li no.
Natural Selection yog dab tsi?
Natural xaiv yog ib qho tseem ceeb ntawm evolution tsim los ntawm Charles Darwin nyob rau hauv 1859. Nws lim genotypes los ntawm lub sij hawm. Nws muaj feem xyuam nrog lub tswv yim ntawm kev sib txawv ntawm lub neej kev loj hlob zoo. Kev xaiv ntuj lim cov kab mob raws li kev loj hlob. Raws li qhov tshwm sim ntawm kev xaiv ntuj, cov pej xeem ntawm cov kab mob muaj sia tau hloov mus rau lawv qhov chaw nyob nrog lub sijhawm.
Daim duab 01: Kev Xaiv Ntuj
Raws li txoj kev xav ntawm kev xaiv ntuj, cov tib neeg uas muaj cov yam ntxwv zoo dua qub rau ib puag ncig zoo dua li lwm tus yuav muaj sia nyob thiab yug dua tshiab. Lawv dhau qhov kev hloov pauv no rau lawv cov xeeb ntxwv. Ib yam li ntawd, los ntawm kev xaiv ntuj, cov yam ntxwv zoo tau dhau los ntawm ib tiam dhau ib tiam. Kev xaiv ntuj piav qhia txog lub neej txawv li cas tsim los ntawm ib tug poj koob yawm txwv nyob rau lub sijhawm.
Dab tsi yog qhov zoo sib xws ntawm Spatial Sorting thiab Natural Selection?
- Spatial sorting thiab natural selection yog ob tug mechanisms ntawm evolution.
- Ob qhov xwm txheej no cuam tshuam nrog ib leeg.
- Ob qho tib si xaiv ntuj thiab kev xaiv tshwj xeeb tshwm sim hauv txhua tiam neeg.
- Lawv xav tau kev hloov pauv qub txeeg qub teg.
- Ob qho tib si ua rau kev txiav txim siab hloov pauv hauv cov cwj pwm phenotypic.
Qhov txawv ntawm Spatial Sorting thiab Natural Selection yog dab tsi?
Spatial sorting yog ib qho evolutionary mechanism uas ua hauj lwm los lim cov genotypes raws li lawv dispersal tus nqi. Ntawm qhov tod tes, kev xaiv ntuj yog ib qho tseem ceeb ntawm kev hloov pauv uas ua haujlwm los lim cov genotypes raws li lawv qhov kev loj hlob. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm spatial sorting thiab natural selection. Ntxiv mus, spatial sorting lim cov kab mob los ntawm qhov chaw thaum lub ntuj xaiv lim cov kab mob los ntawm lub sij hawm.
Daim duab hauv qab no qhia txog qhov sib txawv ntawm qhov sib txawv ntawm qhov sib txawv thiab kev xaiv ntuj tsim hauv daim ntawv tabular rau ib sab ntawm kev sib piv.
Summary – Spatial Sorting vs Natural Selection
Spatial sorting lim tawm cov kab mob los ntawm qhov chaw thaum xaiv ntuj lim tawm cov kab mob mus txog lub sijhawm. Dispersal tus nqi yog qhov kev txhawj xeeb tseem ceeb hauv spatial sorting thaum lub sij hawm yug me nyuam yog qhov kev txhawj xeeb tseem ceeb hauv kev xaiv ntuj. Yog li, qhov no yog cov ntsiab lus ntawm qhov sib txawv ntawm spatial sorting thiab natural selection. Ob qho tib si spatial sorting thiab natural selection cuam tshuam nrog ib leeg nyob rau hauv evolution. Yog li ntawd, genotypes muaj ob qho tib si ntawm sab cev nqaij daim tawv thiab spatial rau lawv lub cev muaj zog zoo tshwm sim thiab hloov zuj zus mus rau tiam tom ntej. Ob lub tswv yim cuam tshuam rau kev hloov pauv ntawm cov cwj pwm dhau ib tiam.
