Ukuguquka kwesimo sezulu inqubo yomhlaba wonke, ngaphezu kokuhlola ikhono lethu lokuzivumelanisa nezimo, kungadala ushintsho ekukhetheni okungokwemvelo kwezinto eziphilayo, njengoba kusikiselwe ucwaningo olushicilelwe ephephabhukwini i »Isayensi»
Futhi, yize inelukuluku lokwazi, lezi zinguquko aziholwa ukwenyuka kwamazinga okushisa, kepha yimvula, ezoba njalo ezindaweni ezithile kunezinye.
Ososayensi bafunde futhi bahlaziya i-database enkulu yezilwane ezahlukahlukene, izitshalo nezinye izinto eziphilayo, kanye namandla abo okusinda nokuzala, aqoqwe emashumini eminyaka amuva nje. Ngale ndlela, bakwazile ukuthola ukuthi enye yezinto ezixhumene nesimo sezulu esibathinta kakhulu iphethini yesomiso nemvula.
»Ukuguquka kwesimo sezulu kwandisa imvamisa yesomiso nezehlakalo zemvula. Ezinye izindawo ziyoma kanti ezinye zimanzi, "kusho u-Adam Siepielski, ongumcwaningi e-University of Arkansas (USA) futhi ongomunye wababhali besifundo. Ngokusho kwakhe, Lokhu kwehlukahluka kungathinta ukuguqulwa okungenziwa yizinto eziphilayo ngenxa yokuziphendukela kwemvelo.
Kubalulekile ukwazi imiphumela ukuguquka kwesimo sezulu okuzoba nayo ezintweni eziphilayo ezahlukahlukene nasekuguqukeni kwazo, ngoba iyona kuphela indlela yokuthi abacwaningi bathole ukuthi benzeni ukuze bathole ukuthi iziphi izinhlobo ezizokwazi ukuzivumelanisa nokuthi zizokwazi kanjani ukwenza lokho. Ngalo mqondo, uSiepielski wakuxwayisa lokho akwaziwa ukuthi izidalwa ezahlukahlukene zizokwazi yini ukuzivumelanisa nezimo. "Impendulo yokuziphendukela kwemvelo ayikacaci, kodwa imiphumela ikhombisa ukuthi ukushintsha kwesimo sezulu kunamandla okuguqula ukuzivumelanisa nezimo emhlabeni wonke."
Uma ubucabanga ukuthi izinhlobo eziningi zezilwane nezitshalo ngeke zikwazi ukumelana nezinguquko ezenzekayo, kuya ngokuya kuba khona ukuthi uqinisile.
