Qhov Tseem Ceeb Qhov txawv - Neoteny vs Progenesis
Thaum lub sijhawm hloov pauv, cov kab mob tsim thiab hloov pauv ntawm lub sijhawm tshwj xeeb uas hu ua Heterochrony. Yog tias kev hloov pauv cuam tshuam rau kev loj hlob heterochronic ntawm lub cev, nws ua rau Paedomorphism. Paedomorphism yog hu ua ib qho kev loj hlob ntawm cov menyuam yaus, qhov chaw uas cov menyuam yaus muaj hnub nyoog dua li cov poj koob yawm txwv. Paedomorphism tuaj yeem tshwm sim vim yog ob qho laj thawj tseem ceeb; Neotenye thiab Progenesis. Neotenye yog qhov xwm txheej uas cov kab mob ntawm cov kab mob loj hlob ntawm cov kab mob tshwm sim hauv qhov xav tau tab sis, kev loj hlob ntawm somatic cell yog retarded. Progenesis yog qhov mob uas qhov kev loj hlob ntawm somatic cell ntawm ib tug kab mob tshwm sim nyob rau hauv qhov yuav tsum tau tus nqi tab sis cov kab mob cell kev loj hlob sai, yog li muab ceev kev sib deev maturation. Qhov sib txawv tseem ceeb ntawm Neoteny thiab Progenesis yog hom Paedomorphism lawv qhia. Neoteny qhia txog kev loj hlob ntawm somatic cell retarded thiab ib txwm kab mob cell loj hlob whereas, Progenesis qhia ceev cov kab mob cell loj hlob thiab ib txwm somatic cell loj hlob.
Neoteny yog dab tsi?
Neoteny feem ntau pom nyob rau hauv cov tub ntxhais hluas, qhov chaw uas lawv qhia txog kev loj hlob ntawm somatic cell retarded thiab ib tug kab mob cell loj hlob. Txoj kev loj hlob ntawm cov kab mob ib txwm sib raug rau niam txiv kab mob kev loj hlob ntawm tes. Cov kab mob hu ua gamete thiab nws nkag mus rau meiosis. Ob txoj kab kab mob tseem ceeb yog lub qe qe thiab cov phev cell. Cov kab mob somatic sib raug rau tag nrho cov kab mob uas tsis yog kab mob thiab lawv raug mitosis thaum lawv faib cov cell.
Nyob rau hauv Neoteny cov tib neeg muaj lub cev kev loj hlob ntawm kev sib deev thaum lawv txoj kev loj hlob thiab kev loj hlob ntawm lwm cov cell thiab cellular kev ua ub no yog retarded. Cov kev hloov neotenic yuav suav nrog lub ntsej muag tiaj tus, caj npab luv thiab ob txhais ceg thiab lub taub hau loj. Nyob rau hauv thawj theem ntawm txoj kev loj hlob, qhov kev hloov neotenic tsis tau pom, tab sis nrog kev loj hlob ntawm cov kab mob los yog tus neeg, lawv tuaj yeem pom pom tau zoo dua.
Daim duab 01: Neoteny
Neoteny yog qhov tshwm sim ntawm kev hloov pauv uas yog epigenetic. Yog li, qhov kev hloov pauv yog tshwm sim los ntawm ib qho tseem ceeb extrinsic xws li ib puag ncig. Cov kev hloov pauv uas tau txais no tuaj yeem cuam tshuam rau lub cev cov metabolism thiab tsim cov tshuaj biochemical xws li enzymes, kev loj hlob, thiab cov tshuaj hormones, thiab lwm yam. Hauv Neoteny, cov yam ntxwv ntawm kev sib deev tseem tsis hloov pauv hauv feem ntau. Lub siab xav teb rau stimuli kuj yog ib txwm nyob rau hauv feem ntau neotenous kab mob.
YYuav ua li cas yog Progenesis?
Progenesis yog hais txog qhov xwm txheej uas cov kab mob qhia tau hais tias kev loj hlob ntawm somatic cell zoo li nws niam nws txiv tiam sis muaj kev loj hlob ntawm cov kab mob nrawm. Yog li ntawd, kev sib deev maturation ntawm lub cev yog nyob rau hauv ib tug ceev ceev thaum lub sij hawm progenesis. Progenesis yog cov txheej txheem sai thiab nrawm. Yog li ntawd, thaum lub sij hawm Progenesis, cov kab mob me me qhia cov yam ntxwv ntawm kev sib deev siab xws li cov yam ntxwv ntawm kev sib deev, thiab lwm yam.
Dab tsi yog qhov zoo sib xws ntawm Neoteny thiab Progenesis?
- Ob leeg Neoteny thiab Progenesis ua rau Paedomorphism thiab qhia cov menyuam yaus yam ntxwv.
- Ob leeg Neoteny thiab Progenesis tshwm sim vim kev hloov pauv heterochronic.
- Ob leeg Neoteny thiab Progenesis muaj feem cuam tshuam nrog cov txheej txheem kev loj hlob.
Qhov txawv ntawm Neoteny thiab Progenesis yog dab tsi?

Summary – Neoteny vs Progenesis
Heterochrony yog ib qho txawv txav ntawm lub sijhawm ntawm kev loj hlob ntawm cov kab mob. Paedomorphism tshwm sim los ntawm kev hloov pauv ntawm heterochronic tuaj yeem raug cais raws li Neoteny thiab Progenesis. Neoteny qhia txog kev loj hlob ntawm kev sib deev li cov niam txiv tab sis qhia txog kev loj hlob ntawm somatic cell retarded. Progenesis qhia tau hais tias ib txwm somatic cell txoj kev loj hlob tab sis qhia tau hais tias ib tug zuj zus kab mob kab cell txoj kev loj hlob. Lub acceleration ntawm kev sib deev maturation yog pom thaum lub sij hawm progenesis. Progenesis yog sai thiab sai. Yog li ob qho xwm txheej no ua rau muaj cov kab mob me me uas cuam tshuam qhov kev loj hlob ntawm cov kab mob. Qhov no yog qhov txawv ntawm neoteny thiab progenesis.
