<prompt> Pfupisa nyaya yacho: Makomba maviri ekare akapoteredza aifungidzirwa kuva akaumbwa nechiitiko chimwe chete chokurova zvino anofungidzirwa kuva akaumbwa nemapuraneti maviri akaparadzana. Pfungwa yokuumbwa isingadaviriki zvikuru yakasvikwa pashure pokunge masayendisiti aongororazve matombo panzvimbo yacho, uye akawana misi yezvinhu zviviri zvacho yakanga yakasiana zvikuru. Nepo dzose dzaifungidzirwa kuva dzine makore ane mamiriyoni 285 okukura, zvino kunoratidzika kuti imwe yemakomba acho chaizvoizvo ine makore ane mamiriyoni 450 okukura asi, netsaona, yakaumbwa munenge munzvimbo imwe cheteyo chaiyoiyo. Dzorera pasi kuti uone vhidhiyo. Makomba maviri eClearwater Lake muCanada angave asina kuumbwa neasteroid miviri. Kufungidzirwa kwaro kuti East crater asteroid yakarova mhoteredzo yegungwa mukati menhambo yeOrdovician, makore ane mamirioni 490 apfuura. Gomba reWest rakagadzirwa munguva yePermian makore 285 miriyoni apfuura uye rakarova nyika yePangea. Vanzveri vepaUniversity of Western Australia vanoti nyanza dzeClearwater muCanada dzakaumbwa nezviitiko zviviri zvakasiyana mungozi chaiyo. Kuwana kunoshamisa uku, kana kukasimbiswa, kune zvakunoreva zvinokosha kune dzimwe dzinonzi ngura mbiri dziri muzuva, dzaimbofungwa kuti dzakaumbwa nematombo maviri kana kuti akawanda akawira panguva imwe chete. Uye musiyano mukuru wenguva uri pakati pezviitiko zviviri zvacho unoshamisa zvikuru sezvo, panguva yakaitwa gomba rokutanga, nzvimbo yechipiri yakanga iri pasi pemvura. Tsvakurudzo yacho yakabudiswa mumagazini inonzi Geochimica et Cosmochimica Acta uye yakataurwa neAstrobiology Magazine. Zvinhu zvinoputika zvinosiya gomba rine dhayamita yemakiromita 100 kana kuti isingasviki, zvakadai sezvakarova madziva eClearwater, zvinofungidzirwa zvikuru kuti hazvina migumisiro yenyika yose. Kutaura zvazviri, kukanganiswa kwezvinhu kunogona kutowedzera kusiyana-siyana kwezvinhu zvipenyu. Somuenzaniso, Great Ordovician Biodiversification Event, iyo yakaona kuwedzera kwenhamba yemarudzi emhuka anenge mamiriyoni 470 emakore akapfuura, yakabatanidzwa nezviitiko zvinowanzoitika panguva iyoyo. Izvi zvichida zvinokonzerwa nokuti kugunzva kungakanganisa upenyu hwomunzvimbomo zvakakwana kuti rumwe rudzi rutonge, kana kuti nemhaka yokuti makomba anotonhora zvishoma nezvishoma anogona kugovera...  <response>: Makomba maviri ari muCanada angave asina kuumbwa neasteroid miviri. Makungwa eClearwater aifungidzirwa kuva ose akaumbwa makore 285m apfuura. Asi kuongorora matombo kunoratidza kuti gungwa reEast rakakura zvikuru. Inofungidzirwa kuva yakasikwa yoga yoga makore 460 mamiriyoni apfuura. Ikoku kunoreva kuti mapako akaumbwa netsaona isingadaviriki zvikurusa yenyeredzi duku mbiri dzinosvika panzvimbo imwe cheteyo, dzakaparadzaniswa namakore mamiriyoni 185.
