Rangarira ndima iri pasi apa uye ipapo pindura mubvunzo gare gare mumutauro mumwe chetewo sechikamu:  Passage: Prokaryotes yakagara pasi pano kubva makore anenge mabhiriyoni 3 kusvika ku4 apfuura. Hapana chinjo dzakajeka dzomuviri kana kuti sangano remasero dzakaitika muzvipenyu izvi mumabhiriyoni mashomanene emakore akatevera. Masero eukaryotic akabuda pakati pemakore 1.6 kusvika ku2.7 bhiriyoni apfuura. Kuchinja kukuru kwakatevera kwakaitika apo mabhakitiriya akaputirwa nemasero eukaryotic, mubatanidzwa wokushandira pamwe unonzi endosymbiosis. Mabhakitiriya akafukidzwa nesero rinogamuchira ipapo akawana coevolution, nemabhakitiriya achichinja kuva mitochondria kana hydrogenosomes. Kumwe kumedzwa kwezvinhu zvipenyu zvakafanana necyanobacteria kwakatungamirira kukuumbwa kwechloroplasts mualgae nemiti. Nhau youpenyu yakanga iri iyo yeunicellular eukaryotes, prokaryotes uye archaea kusvikira anenge makore 610 mamiriyoni apfuura apo zvisikwa zvine masero akawanda zvakatanga kuoneka mumakungwa munguva yeEdiacaran. Kushanduka-shanduka kwemasero akawanda kwakaitika muzviitiko zvakawanda zvakazvimirira, muzvinhu zvipenyu zvakasiyana-siyana zvakadai semasvosve, algae shava, cyanobacteria, slime molds uye myxobacteria. Muna Ndira 2016, masayendisiti akazivisa kuti, anenge mamiriyoni 800 emakore akapfuura, kuchinja kuduku kwemavara anogarwa nhaka mumorekuru rimwe chete rinonzi GK-PID kungave kwakabvumira zvisikwa kuti zvibve pasero rimwe chete zviende kune rimwe remasero akawanda. Nokukurumidza pashure pokuonekwa kwezvisikwa izvi zvokutanga zvine masero akawanda, uwandu hunoshamisa hwemavambo ezvisikwa hwakaoneka mumakore anenge mamiriyoni 10, muchinoitika chinonzi kuputika kweCambrian. Muno, marudzi mazhinji emhuka dzazvino uno akaoneka muzvinyorwa zvezvisaririra, pamwe chete nemitsara yakasiyana nemimwe yakazoparara. Zvinhu zvakasiyana-siyana zvinokonzera kuputika kweCambrian zvakatsanangurwa, kusanganisira kuunganidzwa kweoxygen mumhepo inenge iri mumhepo kubva pakuita photosynthesis. Makore anenge mamiriyoni 500 akapfuura, zvinomera nefungi zvakatanga kugara panyika uye pasina nguva zvakazoteverwa nemapoka emhuka dzinofamba nemapfupa nedzimwewo mhuka. Zvipembenene zvakabudirira zvikuru uye kunyange nhasi zvinoumba rudzi rukuru rwemhuka. Mhuka dzinogara mumvura nedzimwe dzakaoneka kokutanga makore anenge mamiriyoni 364 akapfuura, dzichiteverwa nemhuka dzokutanga dzinogara mumvura nedzimwe dzinogara mumvura neshiri makore anenge mamiriyoni 155 akapfuura...  Mubvunzo: Masero eukaryotic akavapo rini?
Makore mabhiriyoni 1,6 kusvika ku2,7 akapfuura
