Mwanzeru,Pterosauriainali mitundu yoyamba m'mbiri yonse kutha kuuluka momasuka mumlengalenga. Ndipo mbalame zitaonekera, zikuwoneka zomveka kuti Pterosauria inali makolo a mbalame. Komabe, Pterosauria sanali makolo a mbalame zamakono!
Choyamba, tiyeni tidziwike bwino kuti chinthu chofunikira kwambiri pa mbalame ndi kukhala ndi mapiko okhala ndi nthenga, osati kutha kuuluka! Pterosaur, yomwe imadziwikanso kuti Pterosauria, ndi chokwawa chomwe chinatha chomwe chinakhalapo kuyambira kumapeto kwa Triassic mpaka kumapeto kwa Cretaceous. Ngakhale kuti ili ndi makhalidwe ouluka omwe amafanana kwambiri ndi mbalame, ilibe nthenga. Kuphatikiza apo, Pterosauria ndi mbalame zinali m'magulu awiri osiyana mu njira yosinthira. Kaya zinakula bwanji, Pterosauria sinasinthe kukhala mbalame, osatchulanso makolo a mbalame.
Kodi mbalame zinachokera kuti? Pakadali pano palibe yankho lenileni m'gulu la asayansi. Timangodziwa kuti Archeopteryx ndiye mbalame yoyambirira kwambiri yomwe timaidziwa, ndipo idawonekera kumapeto kwa nthawi ya Jurassic, ikukhala m'nthawi yomweyi ndi ma dinosaur, kotero ndikoyenera kunena kuti Archeopteryx ndiye kholo la mbalame zamakono.
N'kovuta kupanga mafupa a mbalame, zomwe zimapangitsa kuti kuphunzira mbalame zakale kukhale kovuta kwambiri. Asayansi amatha kujambula mwachidule mawonekedwe a mbalame yakaleyo kutengera zizindikiro zogawanikazo, koma thambo lenileni lakale lingakhale losiyana kwambiri ndi malingaliro athu, mukuganiza bwanji?
