Nws muaj kev nyab xeeb los xav tias txhua tus neeg uas tau dim ntawm chav kawm biology hauv tsev kawm ntawv theem siab tau hnov ​​​​​​txog qhov kev sim Miller-Urey, uas tau lees paub qhov kev xav tias cov tshuaj lom neeg ntawm lub neej yuav tau pib hauv lub ntiaj teb huab cua qub. Nws yog "xob laim hauv lub raj mis," ib qho teeb tsa iav kaw uas sib tov cov pa roj xws li methane, ammonia, hydrogen, thiab dej nrog ob lub electrodes los muab lub teeb uas ua rau muaj teeb meem ntawm xob laim saum ntuj ua ntej lub neej thaum ntxov. [Miller] thiab [Urey] tau qhia tias cov amino acids (cov khoom siv ntawm cov protein) tuaj yeem npaj tau nyob rau hauv cov xwm txheej ua ntej lub neej.
Tom qab 70 xyoo dhau los, Miller-Urey tseem muaj feem cuam tshuam, tej zaum tseem muaj feem cuam tshuam ntau dua thaum peb nthuav peb lub zog mus rau hauv qhov chaw thiab pom cov xwm txheej zoo ib yam li lub ntiaj teb thaum ub. Qhov kev hloov kho tshiab ntawm Miller-Urey no yog ib qho kev sim los ntawm kev tshawb fawb pej xeem los hloov kho qhov kev sim qub kom ua raws li cov kev soj ntsuam no, thiab tej zaum, tsuas yog txaus siab rau qhov tseeb tias yuav luag tsis muaj dab tsi hauv koj lub tsev rau khoom uas tuaj yeem ua rau muaj kev cuam tshuam tshuaj lom neeg ntawm lub neej.
[Markus Bindhammer's] teeb tsa zoo ib yam li [Miller's] thiab [Urey's] teeb tsa, tab sis qhov sib txawv tseem ceeb yog kev siv plasma ua lub zog hluav taws xob es tsis yog kev tso hluav taws xob yooj yim. [Marcus] tsis tau piav qhia ntxiv txog nws qhov laj thawj rau kev siv plasma, tsuas yog tias qhov kub ntawm plasma siab txaus los oxidize cov nitrogen hauv lub cuab yeej, yog li muab qhov chaw tsis muaj oxygen. Lub plasma tso tawm yog tswj los ntawm microcontroller thiab MOSFETs los tiv thaiv cov electrodes los ntawm melting. Tsis tas li ntawd, cov khoom siv raw ntawm no tsis yog methane thiab ammonia, tab sis yog cov tshuaj ntawm formic acid, vim tias cov cim spectral ntawm formic acid tau pom nyob rau hauv qhov chaw thiab vim tias nws muaj cov tshuaj lom neeg nthuav uas tuaj yeem ua rau muaj cov amino acids.
Tu siab kawg li, txawm hais tias cov khoom siv thiab cov txheej txheem sim yooj yim heev, kev ntsuas cov txiaj ntsig xav tau cov khoom siv tshwj xeeb. [Markus] yuav xa nws cov qauv mus rau kev tshuaj xyuas, yog li peb tsis paub tias cov kev sim yuav qhia dab tsi. Tab sis peb nyiam qhov chaw ntawm no, uas qhia tau tias txawm tias cov kev sim zoo tshaj plaws kuj tsim nyog rov ua dua vim tias koj yeej tsis paub tias koj yuav pom dab tsi.
Zoo li Miller txoj kev sim ua yuav ua rau muaj kev tshawb pom tshiab tseem ceeb heev. Ntau tshaj 40 xyoo tom qab, ze rau qhov kawg ntawm nws txoj haujlwm, nws tau hais tias qhov no tsis tau tshwm sim raws li nws tau cia siab lossis xav tau. Peb tau kawm ntau yam los ntawm txoj kev, tab sis txog tam sim no peb tseem tsis tau muaj qhov xwm txheej ntuj tsim tiag tiag. Ib txhia neeg yuav qhia koj lwm yam. Mus saib lawv cov ntaub ntawv.
Kuv qhia Miller-Urey hauv chav kawm biology hauv tsev kawm qib siab tau 14 xyoo. Lawv tsuas yog ua ntej lawv lub sijhawm me ntsis xwb. Peb nyuam qhuav tshawb pom cov molecule me me uas tuaj yeem tsim cov khoom siv ntawm lub neej. Cov protein tau pom tias muaj peev xwm tsim DNA thiab lwm yam khoom siv. Hauv 30 xyoo, peb yuav paub feem ntau ntawm keeb kwm ntawm keeb kwm ntawm lub cev, kom txog thaum hnub tshiab tuaj txog - kev tshawb pom tshiab.
Thaum koj siv peb lub vas sab thiab cov kev pabcuam, koj pom zoo rau qhov chaw uas peb muab cov ncuav qab zib ua haujlwm tau zoo, ua haujlwm tau zoo thiab tshaj tawm. kawm ntxiv
