Si macquul ah,Pterosauriawaxay ahaayeen noocyada ugu horreeya taariikhda ee awood u leh inay si xor ah ugu duulaan cirka.Ka dib markii shimbiruhu u muuqdaan, waxay u muuqataa mid macquul ah in Pterosauria ay ahaayeen awoowayaasha shimbiraha.Si kastaba ha ahaatee, Pterosauria ma ahayn awoowayaasha shimbiraha casriga ah!
Marka hore, aynu caddayno in astaamaha aasaasiga ah ee shimbiraha ay tahay inay leeyihiin baalal baalal leh, ma awoodaan inay duulaan!Pterosaur, oo sidoo kale loo yaqaan Pterosauria, waa xamaaratada dabar go'ay oo noolaa laga soo bilaabo Triassic Dambe ilaa dhamaadka Cretaceous.Inkasta oo ay leedahay sifooyinka duulista oo aad ugu eg shimbiraha, haddana ma laha baalasha.Intaa waxaa dheer, Pterosauria iyo shimbiraha waxay ka tirsan yihiin laba nidaam oo kala duwan oo ku saabsan habka horumarinta.Si kasta oo ay u horumareen, Pterosauria uma ay u xuubsiibteen shimbiraha, iska daa in ay awoowayaasha shimbiraha iska daayaan.
Haddaba halkee ka soo baxeen shinbiraha?Hadda ma jirto jawaab sax ah oo ka jirta bulshada cilmiga sayniska.Waxaan ognahay oo kaliya in Archeopteryx uu yahay shimbirkii ugu horreeyay ee aan naqaanno, waxayna soo muuqdeen xilligii Jurassic ee dambe, iyagoo ku noolaa isla xilligii dinosaurs-yada, sidaa darteed waxaa habboon in la yiraahdo Archeopteryx waa awoowaha shimbiraha casriga ah.
Way adag tahay in la sameeyo haraaga shimbiraha, taas oo ka dhigaysa daraasadda shimbirihii hore xitaa mid aad u adag.Saynis yahanadu waxay kaliya qiyaas ahaan sawiri karaan dulucda shimbirkii qadiimka ahaa iyagoo ku salaynaya tilmaanahaas kala daadsan, laakiin samada qadiimiga ah ee dhabta ah ayaa laga yaabaa inay gabi ahaanba ka duwan tahay male awaalkeena, maxaad u malaynaysaa?
