<prompt> Fingqa isihloko: Manje sekucatshangwa ukuthi izimbobo ezimbili zasendulo ezizungezile ezazikholelwa ukuthi zakhiwa umthelela ofanayo, zakhiwa ama - asteroid amabili ahlukene. Umbono wokwakheka ongenakwenzeka kakhulu wafinyelelwa ngemva kokuba ososayensi behlaziye kabusha amatshe akule ndawo, futhi bathola ukuthi izinsuku zalezi zindawo ezimbili zazihluke kakhulu. Nakuba kokubili kwakucatshangwa ukuthi kuneminyaka eyizigidi ezingu-285 ubudala, manje kubonakala sengathi omunye wemigodi empeleni uneminyaka eyizigidi ezingu-450 ubudala kodwa, ngengozi, wadalwa cishe endaweni efanayo. Skrolela phansi ukuze ubone ividiyo. Kungenzeka ukuthi izimbobo ezimbili zaseClearwater Lake eCanada azizange zenziwe i - asteroid emibili. Kucatshangwa ukuthi i-East crater asteroid yahlasela indawo yasolwandle phakathi nenkathi ye-Ordovician, eminyakeni eyizigidi ezingu-490 edlule. Umgodi waseNtshonalanga wakhiwa esikhathini sePermian eminyakeni eyizigidi ezingama-285 edlule futhi wahlasela umhlaba wasePangea. Abacwaningi baseNyuvesi yaseNtshonalanga Australia bathi amachibi aseClearwater eCanada akhiwa izenzakalo ezimbili ezihlukene ngokuqondana nje. Lokhu okutholakele okuphawulekayo, uma kuqinisekiswa, kunemithelela ebalulekile kweminye imifantu ebizwa ngokuthi imifantu emibili esimisweni sonozungezilanga, ngaphambili okwakucatshangwa ukuthi yakhiwa amatshe amabili noma amaningi ashayisana ngesikhathi esifanayo. Futhi umehluko omkhulu wesikhathi phakathi kwalezi zenzakalo ezimbili umangalisa ngisho nangokwengeziwe njengoba, ngesikhathi kwenziwa isigodi sokuqala, indawo yesibili yayingaphansi kwamanzi. Lolu cwaningo lwanyatheliswa ephephabhukwini iGeochimica et Cosmochimica Acta futhi kwabikwa ngalo kuyi-Astrobiology Magazine. Ngokuvamile kucatshangwa ukuthi ukuphahlazeka okushiya umhume onobubanzi obungamamayela angu-62 100 km noma ngaphansi, njengaleyo eyashayisa amachibi aseClearwater, akunamphumela womhlaba wonke. Eqinisweni, imiphumela ingakhuphula ngisho nokuhlukahluka kwezinto eziphilayo. Ngokwesibonelo, i-Great Ordovician Biodiversification Event, eyabona ukuqhuma kwenani lezinhlobo zezilwane cishe eminyakeni eyizigidi ezingama-470 edlule, kuye kwahlotshaniswa nezenzakalo ezivamile zokushayisana ngaleso sikhathi. Lokhu kungenzeka kungenxa yokuthi umthelela ungaphazamisa ukuphila kwasendaweni ngokwanele ukuvumela olunye uhlobo ukuba lubuse, noma ngenxa yokuthi izimbobo ezipholile kancane zingase zinikeze...  <response>: Imigodi emibili eCanada kungenzeka ukuthi ayidalwanga i - asteroid emibili. Amachibi aseClearwater kucatshangwa ukuthi akhiwa eminyakeni eyizigidi ezingama-285 edlule. Kodwa ukuhlaziywa kwamadwala kusikisela ukuthi ichibi laseMpumalanga lidala kakhulu. Kucatshangwa ukuthi yadalwa ngokwahlukana eminyakeni eyizigidi ezingu-460 edlule. Lokhu kusho ukuthi lezi zimbobo zakhiwa yinhlanhla engalindelekile kakhulu yokwehla kwama - asteroid amabili endaweni efanayo, ahlukaniswe iminyaka eyizigidi ezingu - 185.
