2026 biology talkshow: 誰是呆腦獸特輯?! 單指奧秘與身世之謎-獸腳亞目 阿瓦拉慈龍類(Alvarezsauria)

from 雷比特生物空中講 · host 雷比特老師

詳細介紹阿瓦拉慈龍類(Alvarezsauria)的演化歷程,這群生物被譽為恐龍界的「極簡主義者」。澄清其命名並非源於物理學家,並解釋牠們如何從擁有三指的肉食性祖先,逐漸演化成體型微小、專精於挖掘蟻巢的單指特化類群。透過對靈手龍、單爪龍與臨河爪龍等物種的比較,揭示其前肢為了生存生態位而產生的極端變革。此外,最新的研究也探討牠們的感官能力與如鳥類般的恆溫睡姿,展現這群小型獸腳類恐龍獨特的生命策略。這套敘事強調演化不一定要追求龐大,透過高度特化與縮小體型,同樣能在古生物史上取得長久的成功。 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/d637ad68788b Powered by Firstory Hosting
