2026 biology talkshow: 誰是呆腦獸特輯?! 龍鳥邊緣的長腿怪客：半鳥科（Unenlagiidae）

詳細介紹分佈於南半球的半鳥科（Unenlagiidae），這是一群在外型與演化地位上介於傳統恐龍與早期鳥類之間的奇特物種。探討學界對其分類的爭議，指出其特殊的肩帶構造具備類似鳥類的撲翼潛力，使其演化定位逐漸由馳龍類向基幹鳥類偏移。透過對科馬唯半鳥、鷲盜龍、雷奇瓜納魔鳥及南方盜龍等成員的解構，揭示該家族從小型精巧到巨大食魚者的多樣化生態。最後，強調半鳥科擁有適於高速奔跑的長腿與足部構造，與北半球馳龍的獵食策略截然不同，展現生命演化過程中豐富的馬賽克式特徵。聽完後可以自主進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址  https://gemini.google.com/share/02b4126bb476 Powered by Firstory Hosting
