A imfihlakalo ososayensi emhlabeni wonke

Ososayensi abaningi baye wafunda isikhathi eside yayingidida umzimba, esasihlukile kuzo zonke ezinye ezakheke esiphambanweni. Ngemva kwenkathi ethile yesikhathi, le mfihlakalo ixazululiwe. Kwatholakala ukuthi lesi silwane sinamakhanda emibili kwemisila emibili - kukhona izimpethu ezimbili aningishiyanga uvalwe komunye nomunye.

Yiqiniso, amaqiniso amangalisayo ngalezi izimpethu akuzona eziningi kangaka, kodwa. Ngisho naphezu kweqiniso lokuthi izilwane ezincane zigcwele izimfihlakalo Imbalwa kakhulu ozakwabo emikhulu, kunjalo futhi nemvelo kubalulekile futhi ezidingekayo.
