Nchintu chili kabotu kuyeeya kuti kufumbwa muntu wakafwutuka mukkilasi ya biology kuchikolo cha sekkondali wakamvwa aatala a Miller-Urey experiment, eeyo yakasinizya muzeezo wakuti chemistry yabuumi ilakonzya kuti yakatalikila mumulengalenga wanyika. Mubwini "mulabi uuli mubbodela," gilazi lijalidwe lisanganya muya mbuli methane, ammonia, haayidirojeni, amaanzi antoomwe ama electrode obile kuti kube mumuni uukozyanisya mumuni uumweka mujulu kakutanaba buumi bwakusaanguna. [Miller] a [Urey] bakatondezya kuti ma amino acid (zintu ziyaka ma protein) alakonzya kubambwa mubukkale butanapona.
Kuya kunembo myaaka iili 70 mpawo Miller-Urey uchili aampindu, amwi kwiinda waawo mbuli mbutuyaabuya mujulu akujana bukkale bulikozyene anyika yakusaanguna. Eeyi nzila yakacincwa ya Miller-Urey nkusola kwasayaansi yabantu kuti ichinche nzila yakusunka yachiindi kuti izumanane azintu eezyi zyabonwa, mpawo, ambweni, ukkomane akuti kunyina chintu mugalaji yako chikonzya kuleta kusanduka kwamakemikalu mubuumi.
Bubambe bwa [Markus Bindhammer] bulikozyene munzila zyiingi abwa [Miller] a [Urey], pesi kusiyana kupati nkubelesya plasma mbuli nzila yakujana manguzu kutali buyo kugwisya magesi. [Marcus] tanaakapandulula kaambo nkaakabelesya plasma, kunze lyakuti kupya kwa plasma kulisumpukide loko kuti kulakonzya kupa kuti nitrogen mukati kachintu eechi ichite oxidize, aboobo kupa busena butakwe oxygen. Kuzwa kwa plasma kweendelezyegwa a microcontroller antoomwe a MOSFETs kuchitila kuti ma electrode atanyonyooki. Alubo, zintu zitabelesyegwi aawa tazili methane a ammonia pe, pesi musamu wa formic acid, nkaambo citondezyo cha formic acid chakajanwa mujulu alimwi nkaambo chili abubambe bwamakemikalu bukonzya kusololela kukupangwa kwa amino acids.
Mupenzi, nikuba kuti zibelesyo anzila zyakusola nziubauba, kupima mpindu kuyandika zibelesyo zilibedelede. [Markus] ulatuma zitondezyo zyakwe kuti zilangwe-langwe, aboobo tatuzi pe kuti masunko ayootondezya nzi. Asi tulayanda busena aawa, ibutondezya kuti nikuba masunko mapati ayelede kwiindulukwa nkaambo tokonzyi kuziba ncho uyoojana.
Chakali kulibonya kuti kusola kwa Miller kwakali kuyoosololela kukujana zintu zipya ziyandikana loko. Nikwakainda myaka iitandila makumi aane, kumamanino aamulimo wakwe, wakatondeezya kuti eezi tiizyakachitika mbuli mbwaakali kulangila. Twakaiya zyingi munzila, pesi kusikila lino tuli kule akuba chintu cheenzu. Bamwi bantu balakwaambila zimbi. langa zibelesyo zyabo.
Ndakayiisya Miller-Urey mumakkilasi aa biology yaku kkoleji kwamyaka ilikkumi ayone. Bakali kunembo mbichaani achiindi chabo. Twajana buyo tuniini-niini itukonzya kuyaka zintu zipa buumi. Ma protein atondezyedwe kuti alakonzya kupanga DNA azintu zimwi ziyaka. Mumyaka iili 30, tulaziba makani manji aajatikizya matalikilo aabuumi, kusikila buzuba bupya busike – kujana kupya.
