Txhua yam ntawm lub neej yog theorized kom muaj hloov zuj zus los ntawm cov thawj prokaryotes, tej zaum 3.5-4.0 billion xyoo dhau los. Cov tshuaj thiab lub cev tej yam kev mob ntawm lub ntiaj teb primitive yog invoked los piav qhia lub hauv paus ntawm lub neej, uas yog ua ntej los ntawm tshuaj evolution ntawm cov organic tshuaj.
Ntxiv rau qhov no, tshuaj evolution txawv li cas ntawm cov evolution lom?
Tswv yim: Tshuaj evolution yog cov txheej txheem ntawm kev tsim ntawm feem ntau ruaj khov molecules los ntawm ntau yam me me. Biological evolution txhais tau tias yog kev hloov pauv caj ces hauv cov pej xeem uas tau txais los ntawm ntau tiam neeg.
Tsis tas li ntawd, cov tshuaj evolution hypothesis yog dab tsi? Hauv evolutionary biology, ntawm qhov tod tes, lo lus " tshuaj evolution " feem ntau yog siv los piav txog qhov kev xav hais tias organic tsev blocks ntawm lub neej raug tsim thaum inorganic molecules tuaj ua ke. Qee zaum hu ua abiogenesis, tshuaj evolution yuav ua li cas lub neej pib hauv ntiaj teb.
Yog li ntawd, thaum twg tshuaj evolution pib nyob rau lub ntiaj teb?
Lub hnub nyoog ntawm lub ntiaj teb yog kwv yees li 4.54 billion xyoo; Cov pov thawj ntxov tshaj plaws ntawm lub neej hauv ntiaj teb hnub los ntawm tsawg kawg 3.5 billion xyoo dhau los, thiab tej zaum yuav ntxov li Eoarchean Era (nruab nrab ntawm 3.6 thiab 4.0 billion xyoo dhau los ), tom qab geological crust pib solidify tom qab lub molten Hadean Eon.
Cov kws tshawb fawb ntseeg tias tshuaj evolution tshwm sim qhov twg?
nyob ntawd yog ib tug xov tooj ntawm hypotheses nyob rau hauv thawj lub hauv paus ntawm lub neej. Qhov kev xav tau yog tias thawj cov molecular replicators tuaj rau hauv lub neej nyob ze ntawm cov cua kub hauv dej hiav txwv, hauv qhov tsua tob, lossis hauv cov dej ntiav ze ze ntawm lub roob hluav taws.

Qhov twg los thawj qhov ntev lossis qhov dav lossis qhov siab?
Dab tsi los ua ntej? Graphics 'kev lag luam tus qauv yog dav los ntawm qhov siab (dav x qhov siab). Txhais tau hais tias thaum koj sau koj qhov ntsuas, koj sau lawv los ntawm koj qhov kev xav, pib nrog qhov dav. Qhov ntawd tseem ceeb
Dab tsi yog tsib yam pov thawj uas koj tuaj yeem siv los txiav txim seb puas muaj tshuaj lom neeg tshwm sim?
Qee cov cim qhia txog kev hloov tshuaj lom neeg yog kev hloov xim thiab tsim cov npuas. Lub tsib yam kev hloov ntawm tshuaj lom neeg: xim chage, tsim ntawm precipitate, tsim cov roj, tsw hloov, kub hloov
Dab tsi yog qhov sib txawv tseem ceeb ntawm tshuaj lom neeg thiab cov tshuaj tiv thaiv nuclear Lub hlwb?
(1) Cov tshuaj tiv thaiv Nuclear cuam tshuam nrog kev hloov pauv ntawm inan atom lub nucleus, feem ntau tsim cov khoom sib txawv, nrog rau kev tawm ntawm cov hluav taws xob xws liα, β thiab gamma; lwm ray. Cov tshuaj tiv thaiv tshuaj, ntawm qhov tod tes, tsuas yog muaj kev hloov pauv ntawm cov hluav taws xob thiab tsis cuam tshuam nrog kev hloov pauv hauv cov nuclei
Qhov twg ntawm 1905 cov ntaub ntawv tau muab thawj qhov pov thawj zoo rau lub neej ntawm atom?
Annus mirabilis cov ntaub ntawv
Dab tsi yog tshuaj lom neeg cov tshuaj tiv thaiv thiab cov tshuaj tiv thaiv lub cev?
Qhov sib txawv ntawm cov tshuaj tiv thaiv lub cev thiab cov tshuaj tiv thaiv tshuaj yog muaj pes tsawg leeg. Hauv cov tshuaj tiv thaiv tshuaj, muaj kev hloov pauv ntawm cov tshuaj hauv nqe lus nug; nyob rau hauv ib qho kev hloov ntawm lub cev muaj qhov sib txawv ntawm qhov tsos, tsis hnov tsw, los yog cov duab yooj yim ntawm cov qauv ntawm cov teeb meem yam tsis muaj kev hloov pauv hauv cov ntsiab lus
