Ethi Mysteries of the emhlabeni - i iCambrian

Ngokusho isayensi olusemthethweni, izinto eziphilayo kule planethi ngoba ezingaba yizigidi eziyizinkulungwane ezintathu edlule ngesimo eziphilayo elula - angawodwa izinduku ezincane, izakhiwo filamentary, eyindilinga futhi zikanhlangothiningi-oluncane ulwelwe. La magciwane angaba khona kuphela amanzi kuphela ezindaweni efudumele.

Ngokuvamile, ukuthi ngasinda izinsalela zamathambo ezimbalwa kakhulu kusukela enkathini Precambrian. Evolution kubonakala ekhuluphalisiweyo kusukela kwasungulwa ukuphila iminyaka izigidi eziyizinkulungwane ezintathu, ukushintsha futhi siphelelisa zilwane ekhona kuphela ulwelwe nezinto eziphilayo ezincane.

Nokho, eminyakeni million 580 edlule, ngesikhathi senguquko emlandweni kwemvelo - the iCambrian. ubude bayo luphakathi ukuphila Zomhlaba incane - iminyaka eyizigidi ezingu-80. Yingaleso sikhathi lapho ngokuzumayo futhi cishe kanyekanye kuvele ezihlukahlukene ezimangalisayo zezinto eziphilayo ezilwane ezingenamgogodla. Okubaluleke kakhulu - eziphilayo ngesikhathi esifushane bakwazi ukuthola okuqinile calcareous skeleton.

Multiple izinhlobo begazi we eCambria kwaba owandulela zonke izinhlobo zokuphila kwanamuhla, kuhlanganise nabantu. Lena nesenzakalo yesikhathi esisodwa kanye ukwehluka abukhali zezinto eziphilayo eyaziwa ngokuthi ukuqhuma eCambria.

Land ngesikhathi khona pustnynyu ngokuphelele, zonke izinto eziphilayo bagxila kuphela emanzini. Amazwekazi zomhlaba kwadingeka indawo ehluke ngokuphelele: isibonelo, esizeni Greenland kanye ne- North America eseningizimu nezwekazi Lavrentsov kwaba ezwekazini Brazilian. Arabia, Afrika futhi Madagascar babe yezwekazi lase-Afrika ebumbene, etholakala enyakatho-mpumalanga yezwe isiRashiya, ahlukaniswe Strait of laseSiberia ezijulile futhi ezwekazini Chinese. Eningizimu, kwakukhona ezwekazini giant Australian, okuyinto kamuva yahlukana yaba India, e-Australia futhi iziqhingi eziningi.

Esikhathini iCambrian sekukhona entabeni abathile banamuhla: Northern Appalachian Izintaba, le Sayan Ridge Mountains Chingiztau (Kazakhstan).

Ngo amanzi, ngokushesha iqhakazile ukuphila: kokuba sokunethezeka trilobite, radiolarians, izipanji, brachiopods. archeocyathids Uvele - izilwane ezinamangqamuzana amaningi, okuyinto esiphambanweni phakathi kwamakhorali futhi neziponji. Bona bakamalalahlengezela nasezinsikeni phansi imizimba amanzi, ukwakha uhlobo izixhobo zama-coral. Ngu ekupheleni eCambria, baba yokuqothulwa.

Ngalesi sikhathi, ikakhulukazi trilobite yaqhakaza - eyisinambuzane bakudala like woodlice yesimanje. Babefanele eyisicaba disk emise ne zempi chitinous, ihlukaniswe 45-50 izingxenye kanye sebuningini imilenze.

Ngasekupheleni we eCambria kwakukhona ezilwaneni ezinomgogodla ezinamehlo lokuqala armored, inhlanzi prototypes.

Ngakho, ngaphandle amafomu soguquko Lesisemkhatsini zinhlobo esibophezelayo amagciwane athile kanye lenyama emhlabeni ngokuzuma kwakhiwa ezilwane ezingenamgogodla kanye yezilwane ezinomgogodla eziningi, prototypes amafomu yesimanje. I iCambrian kuyinto okuyimfihlakalo gxuma obuphathekayo benkolelo yazo ezindaweni umlando emhlabeni.

Ezimweni eziningi abacwaningi wayecabanga ukuthi lokhu umcimbi ekuqongeleleni wamavukelambuso ezibucayi oxygen emoyeni olwandle, kanye okwandisa nosawoti ngamanzi sushi nokukhuphula lokuhlala calcium ne-magnesium emanzini. I chemical ukubunjwa amanzi ishintshile kangangokuthi izinto eziphilayo lapho, ngikutholile eziningi amathuba ushintsho kanye kumiswa zilwane.

Ngisho basikisela ukuthi cishe ngalesi sikhathi, i-Earth ukwenze umbuso okungazelelwe cishe ngo-90 degrees, yingakho kwakukhona shift amadlingozi wonke amazwekazi, ukuqhela zomhlaba kanye kumiswa impumuzo yesimanje ye komhlaba. Iphinde ukuthonywa kumiswa kwezinhlobo ezintsha futhi ezincwadini ukusinda.

Izinkathi yokuziphendukela kwemvelo eMhlabeni wahlangana eziningi izinhlekelele Ngakho, cishe ngasikhathi sinye futhi ngaphandle kokukhetha izibankwakazi wanyamalala eminyakeni million 65 edlule. Futhi ngenkathi Permian esikhathini esifushane ngesikhathi esifanayo kwaba yokuqothulwa cishe 95% eziphila olwandle - kwaba iminyaka eyizigidi 245 edlule.

Kodwa phakathi kwakho konke lokhu izimfihlakalo kuphela iCambrian kuyahluka zokudala yayo, kunokuba ukubhujiswa zilwane. Abaphikisi indlela ukuziphendukela kwemvelo owabona iphazili we eCambria ukuqhuma isiqinisekiso uNkulunkulu asungula ngayo izindlela zanamuhla zokukhulekela eziphilayo, kuhlanganise nabantu.
