Qhov sib txawv tseem ceeb ntawm anagenesis thiab cladogenesis yog tias anagenesis yog txheej txheem uas dhau mus rau phyletic evolution hauv ib hom kab mob, thaum cladogenesis yog hom kev hloov pauv uas cov poj koob yawm txwv tau faib ua ntau hom tshiab.
Evolution yog txheej txheem uas cuam tshuam txog kev hloov pauv ntawm cov yam ntxwv tseem ceeb ntawm cov neeg lom neeg uas tshwm sim ntau tiam neeg. Hauv lwm lo lus, nws yog cov txheej txheem ntawm kev hloov pauv lom neeg nrog rau lub sijhawm. Evolution tshwm sim los ntawm kev sib txawv mechanisms. Anagenesis thiab cladogenesis yog ob hom kev ua haujlwm zoo li no. Thaum lub sij hawm anagenesis, ib lub pas dej ib leeg hloov mus rau hauv lwm lub gene pas dej, thaum lub sij hawm cladogenesis, ib tug tib gene pas yog muab faib mus rau hauv sib txawv gene pas.
Anagenesis yog dab tsi?
Anagenesis yog txheej txheem los ntawm kev hloov pauv hloov pauv tshwm sim hauv ib kab ntawm cov kab mob uas ib qho taxon hloov los ntawm lwm tus taxon tsis muaj ceg. Nyob rau hauv lwm yam lus, nws yog ib tug zuj zus evolution los yog phyletic evolution. Qhov no tshwm sim thaum tib neeg lossis ib hom kab mob tshwj xeeb hauv kev teb rau ib puag ncig ib puag ncig. Qhov no txhawb cov tsiaj mus rau qib siab dua los ntawm kev nce ntxiv hauv kev nyuaj thiab kev ua kom zoo tshaj plaws ntawm kev hloov pauv. Thaum lub sij hawm anagenesis, ib lub pas gene hloov mus rau lwm lub gene pas.
Daim duab 01: Anagenesis
Cov yam ntxwv ntawm anagenesis suav nrog kev faib ua haujlwm hauv lub cev, nce qhov nyuaj ntawm lub hauv nruab nrab paj hlwb thiab cov kabmob muaj feem xyuam, nce qhov nyuaj ntawm lub cev los txhim kho kev ua haujlwm thiab kev xav tau, thiab ua rau muaj kev tiv thaiv ntau ntxiv rau cov kev hloov pauv ntawm ib puag ncig ib puag ncig.. Muaj peb yam tseem ceeb ntawm anagenesis raws li qhov ceev ntawm cov txheej txheem. Lawv yog tachytely, horotely, thiab bradytely. Tachytely yog hom anagenesis ceev uas qhov hloov ntawm taxon tshwm sim nyob rau hauv ib lub sij hawm luv luv. Bradytely yog hom qeeb ntawm anagenesis, thaum horotely anagenesis pib ntawm qhov nrawm nrawm.
Cladogenesis yog dab tsi?
Cladogenesis yog txheej txheem los ntawm kev hloov pauv ntawm ib hom tshwm sim qhov twg cov hom tshiab tau txiav tawm los ntawm hom poj koob yawm txwv. Qhov no yog hom hom ntawm speciation nrog cov lus teb rau sab nraud ib puag ncig stimuli. Thaum lub sij hawm cladogenesis, ntau tshaj ib hom yog tsim los ntawm ib hom. Yog li ntawd, thaum lub sij hawm cladogenesis, ib lub pas dej ua ke hloov mus rau hauv cov noob sib txawv. Cov txheej txheem no coj kev lom zem ntau haiv neeg rau ib puag ncig, thiab nws yog cov txheej txheem evolutionary nquag. Branching evolution yog lwm lo lus los piav txog cov txheej txheem cladogenesis.
Daim duab 02: Speciation
Nrog rau kev siv ceev, peb tuaj yeem faib cladogenesis ua peb hom. Lawv yog tachyschizia, horoschizia, thiab bradyschizia. Thaum lub sij hawm tachyschizia, kab sib cais sai heev vim yog kev ploj tuag ntawm cov neeg sib tw lossis kev cuam tshuam ntawm cov chaw nyob tshiab. Hauv cov xwm txheej zoo li no, kev sib txawv sai sai tshwm sim los hloov mus rau ib puag ncig tshiab nrog cov hauv kev zoo los ntawm kev nce lawv cov lej. Thaum lub sij hawm horoschizia thiab bradyschizia, cladogenesis tshwm sim ntawm tus nqi nruab nrab thiab qeeb qeeb, feem.
Dab tsi yog qhov zoo sib xws ntawm Anagenesis thiab Cladogenesis?
- Anagenesis thiab cladogenesis yog hom kev hloov pauv hloov pauv.
- Ob leeg tshwm sim los teb rau sab nraud ib puag ncig stimuli.
- Ntxiv mus, cov txheej txheem no ua rau muaj qhov tshwj xeeb.
- Lawv raug categorized ua subtypes los ntawm qhov ceev ntawm qhov tshwm sim.
Qhov txawv ntawm Anagenesis thiab Cladogenesis yog dab tsi?
Qhov sib txawv tseem ceeb ntawm anagenesis thiab cladogenesis yog tias anagenesis yog txheej txheem uas dhau mus rau phyletic evolution nyob rau hauv ib hom kab mob, thaum cladogenesis yog hom kev hloov pauv uas faib cov poj koob yawm txwv rau ntau hom tshiab. Thaum lub sij hawm anagenesis, ib lub pas dej ib leeg hloov mus rau hauv lwm lub gene pas dej, tab sis thaum lub sij hawm cladogenesis, ib lub noob caj noob ces faib rau hauv cov gene pas sib txawv. Ntxiv mus, raws li qhov ceev ntawm cov txheej txheem, muaj peb hom anagenesis thiab cladogenesis. Anagenesis hom yog tachytely, horotely, thiab bradytely. Hom Cladogenesis yog tachyschizia, horoschizia, thiab bradyschizia.
Cov hauv qab no qhia txog qhov sib txawv ntawm anagenesis thiab cladogenesis hauv daim ntawv qhia rau ib sab ntawm kev sib piv.
Summary – Anagenesis vs Cladogenesis
Evolution yog ib txoj hauv kev uas hloov pauv ntawm cov yam ntxwv ntawm cov kab mob lom neeg tshwm sim ntau tiam neeg. Anagenesis thiab cladogenesis yog ob hom kev ua haujlwm zoo li no. Qhov sib txawv tseem ceeb ntawm anagenesis thiab cladogenesis yog tias anagenesis yog ib qho txheej txheem uas dhau mus rau phyletic evolution hauv ib hom kab mob. Cladogenesis yog ib hom kev hloov pauv uas faib cov poj koob yawm txwv rau hauv ntau hom tshiab. Nyob rau hauv anagenesis, ib tug tib gene pas hloov mus rau hauv lwm gene pas dej ua ke. Txawm li cas los xij, nyob rau hauv cladogenesis, ib lub gene pas dej sib cais rau hauv cov gene sib txawv.
