U fiirso qoraalka hoose ka dibna ka jawaab su'aasha kadib isla luqadda qoraalka:  Halka laga soo gudbay: Buugga Stephen Jay Gould ee Wonderful Life, oo la daabacay 1989, wuxuu soo jiitay dareenka dadweynaha ee burburka Burgess Shale. Gould wuxuu soo jeedinayaa in kala duwanaanshaha aan caadiga aheyn ee lafa-goysyadu ay muujinayaan in qaababka nolosha ee waqtigaas ay aad uga kala duwanaayeen qaab-dhismeedka jirka marka loo eego kuwa maanta nool, iyo in fara badan oo ka mid ah hiddo-wadaha gaarka ah ay ahaayeen tijaabooyin horumarineed oo dabar go'ay. Faahfaahinta Gould ee kala duwanaanshaha xayawaanka Cambrian waxay si weyn ugu tiirsan tahay dib-u-falanqaynta Simon Conway Morris ee daabacaadaha asalka ah ee Charles Walcott. Si kastaba ha noqotee, Conway Morris si adag ugama raacsanayn natiijooyinka Gould, isagoo ku dooday in ku dhowaad dhammaan noolaha Cambrian loo kala saari karo noocyada casriga ah. Burgess Shale waxay soo jiidatay xiisaha paleoclimatologists ee doonaya inay bartaan oo saadaaliyaan isbeddelada mustaqbalka ee cimilada Dunida. Sida laga soo xigtay Peter Ward iyo Donald Brownlee oo ku jira buugga 2003 The Life and Death of Planet Earth, cilmi-baarayaasha cimiladu waxay bartaan diiwaanada qashin-qubka ee Burgess Shale si ay u fahmaan cimilada qaraxii Cambrian, waxayna u adeegsadaan inay saadaaliyaan waxa cimilada Dunidu u ekaan doonto 500 milyan oo sano mustaqbalka marka kuleylka iyo ballaarinta Qorraxda oo ay weheliso hoos u dhaca CO2 iyo heerarka oksijiinta ayaa ugu dambeyntii kululeynaya Dhulka heerkul aan la arkin tan iyo Archean Eon 3 bilyan oo sano ka hor, ka hor inta aan dhirta iyo xayawaanka ugu horreeya muuqan, sidaas darteedna fahmaan sida iyo goorta noolaha ugu dambeeya ay u dhiman doonaan. Sidoo kale eeg Mustaqbalka Dhulka.  Su'aal: Muxuu ahaa ujeedada sheekada Nolosha Cajiibka ah ee Gould?
