Qhov sib txawv tseem ceeb ntawm atavism thiab retrogressive evolution yog tias atavism yog qhov tshwm sim tam sim ntawd ntawm cov poj koob yawm txwv cov cim nyob rau hauv ib tug neeg thaum retrogressive evolution yog kev hloov ntawm hom nyob rau hauv tag nrho cov pej xeem mus rau primitive cim.
Cov yam ntxwv tuaj yeem tshwm sim lossis ploj mus dhau sijhawm. Thoob plaws hauv cov txheej txheem evolutionary, cov yam ntxwv ntawm poj koob yawm txwv tau hloov lossis ploj mus ntau tiam neeg. Tsis tas li ntawd, cov kab mob tsim los ntawm cov ntaub ntawv yooj yim mus rau cov ntaub ntawv complex. Kev xaiv ntuj yog ib qho tseem ceeb ntawm kev hloov pauv. Atavism thiab retrogressive evolution yog ob lub ntsiab lus uas piav txog qhov yooj yim ntawm cov qauv. Atavism yog qhov rov tshwm sim ntawm cov poj koob yawm txwv uas tau ploj mus thaum lub sijhawm hloov pauv. Nyob rau hauv retrogressive evolution, kab mob loj hlob mus rau hauv cov ntaub ntawv yooj yim los ntawm complex cov ntaub ntawv. Hauv ob qho xwm txheej, cov kab mob txav mus rau cov yam ntxwv tseem ceeb.
Atavism yog dab tsi?
Atavism yog qhov tshwm sim tam sim ntawd ntawm cov yam ntxwv ntawm poj koob yawm txwv hauv ib tus neeg. Feem ntau, cov kab mob tau hloov zuj zus mus rau lub sijhawm, thiab lawv poob cov yam ntxwv ntawm poj koob yawm txwv. Qee cov poj koob yawm txwv zoo uas tau ploj mus thaum lub sij hawm evolution dhau ntau tiam neeg tuaj yeem rov tshwm sim hauv cov kab mob. Atavism hais txog qhov rov tshwm sim ntawm cov poj koob yawm txwv zoo nyob rau tiam tom ntej. Atavism tau pom nyob rau hauv tib neeg thiab. Cov me nyuam yug los nrog vestigial tails, tib neeg muaj cov hniav loj, thiab xim dig muag yog cov piv txwv ntawm atavism hauv tib neeg. Qaib nrog cov hniav thiab ntses taub ntswg ntev nrog ob txhais ceg yog ob qho piv txwv ntxiv rau atavism.
Daim duab 01: Atavism
Muaj ntau yam ua rau atavism. Vim muaj kev hloov pauv, cov noob dormant lossis txwv tsis pub muaj peev xwm qhia tau, muab cov txiaj ntsig ntawm poj koob yawm txwv. Tsis tas li ntawd, kev ua yuam kev hauv kev tswj noob caj noob ces tuaj yeem thim rov qab yam ntxwv ntawm poj koob yawm txwv.
Retrogressive Evolution yog dab tsi?
Kev hloov pauv hloov pauv hloov pauv yog qhov rov qab ntawm hom ntawm tag nrho cov pej xeem mus rau ib lossis lwm yam ntawm lawv cov qauv ua ntej. Qhov no yog hom kev simplification ntawm cov qauv. Feem ntau, nyob rau hauv retrogressive evolution, reappearance ntawm poj koob yawm txwv cim tshwm sim. Txawm li cas los xij, tsis zoo li hauv atavism, qhov rov tshwm sim tshwm sim hauv tag nrho cov pej xeem, tsis txwv rau ib tus neeg. Yog li ntawd, nyob rau hauv retrogressive evolution, kab mob loj hlob mus rau hauv cov ntaub ntawv yooj yim.
Retrogressive evolution yog qhov ntxeev ntawm kev vam meej. Nyob rau hauv cov evolution zuj zus, cov ntaub ntawv yooj yim ntawm cov kab mob loj hlob mus rau hauv cov ntaub ntawv complex. Lawv muaj ib tug heev complex qauv. Txawm li cas los xij, vim muaj kev hloov pauv zuj zus, lawv dhau los ua neeg ywj pheej. Retrogressive evolution yog muaj nyob rau hauv cov kab mob parasitic. Cov kab mob parasitic tsim lawv tus kheej cov khoom noj ntau dua li muab lub zog los ntawm lawv cov tswv.
Dab tsi yog qhov zoo sib xws ntawm Atavism thiab Retrogressive Evolution?
- Ob qho tib si atavism thiab retrogressive evolution yog ob qhov tshwm sim uas yooj yim rau cov qauv ntawm lub cev.
- Nyob rau hauv ob qho tib si atavism thiab retrogressive evolution, kab mob txav mus rau hauv daim ntawv yooj yim lossis daim ntawv poj koob yawm txwv.
- Nyob rau hauv ob qho tib si, kab mob ploj zuj zus tuaj.
Qhov txawv ntawm Atavism thiab Retrogressive Evolution yog dab tsi?
Atavism yog qhov tshwm sim tam sim ntawm cov poj koob yawm txwv hauv ib tus neeg. Retrogressive evolution yog tus txheej txheem ntawm loosing evolved nta vim kev txav ntawm cov kab mob los ntawm cov ntaub ntawv nyuaj rau cov ntaub ntawv yooj yim. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm atavism thiab retrogressive evolution.
Hauv qab no yog cov ntsiab lus ntawm qhov sib txawv ntawm atavism thiab retrogressive evolution.
Summary – Atavism vs Retrogressive Evolution
Atavism yog qhov rov tshwm sim ntawm ib qho koob yawm txwv uas tau ploj mus thaum lub sijhawm hloov pauv. Yog li ntawd, cov yam ntxwv ntawm poj koob yawm txwv tuaj yeem tshwm sim nyob rau tiam tom ntej, feem ntau yog vim muaj kev hloov pauv lossis ua tsis raug ntawm kev tswj hwm noob. Retrogressive evolution yog kev hloov pauv ntawm cov kab mob los ntawm cov ntaub ntawv nyuaj rau cov ntaub ntawv yooj yim. Cov kab mob ploj zuj zus tuaj. Hauv lwm lo lus, nws yog kev txav ntawm cov kab mob mus rau cov cim qub. Retrogressive evolution yog qhov opposite ntawm kev vam meej evolution. Yog li, qhov no yog cov ntsiab lus ntawm atavism thiab retrogressive evolution.
