Ngokunengqondo,I-Pterosauriakwakuyizinhlobo zokuqala emlandweni ukukwazi ukundiza ngokukhululeka esibhakabhakeni.Futhi ngemva kokuvela kwezinyoni, kubonakala kunengqondo ukuthi iPterosauria yayingokhokho bezinyoni.Nokho, iPterosauria yayingebona okhokho bezinyoni zanamuhla!
Okokuqala, masikucacise ukuthi isici esiyisisekelo sezinyoni ukuba namaphiko anezimpaphe, hhayi ukukwazi ukundiza!I-Pterosaur, eyaziwa nangokuthi i-Pterosauria, iyisilwane esihuquzelayo esingasekho esasihlala kusukela eLate Triassic kuze kube sekupheleni kweCretaceous.Nakuba inezici zokundiza ezicishe zifane nezinyoni, azinazo izimpaphe.Ngaphezu kwalokho, i-Pterosauria nezinyoni kwakungokwezinhlelo ezimbili ezihlukene ngenqubo yokuziphendukela kwemvelo.Kungakhathaliseki ukuthi yakhula kanjani, iPterosauria yayingenakuguqukela ekubeni izinyoni, ingasaphathwa eyokhokho bezinyoni.
Ngakho izinyoni zavelaphi?Okwamanje ayikho impendulo eqondile emphakathini wesayensi.Sazi kuphela ukuthi i-Archeopteryx iyinyoni yokuqala esiyaziyo, futhi yavela ekupheleni kwesikhathi seJurassic, ehlala ngesikhathi esifanayo nama-dinosaurs, ngakho-ke kufanelekile ukusho ukuthi i-Archeopteryx ingukhokho wezinyoni zanamuhla.
Kunzima ukwenza izinsalela zezinyoni, okwenza ukucwaninga ngezinyoni zasendulo kube nzima nakakhulu.Ososayensi bangakwazi ukudweba cishe uhlaka lwenyoni yasendulo ngokusekelwe kulezo zinkomba ezihlukene, kodwa isibhakabhaka sangempela sasendulo singase sehluke ngokuphelele emcabangweni wethu, ucabangani?
