2026 biology talkshow: 誰是呆腦獸特輯?! 天空的繼承者:鳥翼類演化支(Avialae)

from 雷比特生物空中講 · host 雷比特老師

詳細描繪鳥類從獸腳類恐龍演化而來的漫長歷程,並回顧從赫胥黎到現代古生物學的科學範式轉移。探討支持飛行的關鍵生理機制變革,例如氣囊系統、半月形腕骨的預適應,以及不對稱飛羽的空氣動力學功能。透過解析始祖鳥、孔子鳥與維加鳥等指標性化石,具體呈現鳥翼類在侏羅紀與白堊紀的輻射演化與多樣生態位。最後分析白堊紀末期大滅絕的篩選壓力,解釋為何棲息於林間的反鳥類悉數滅亡,而部分今鳥類則憑藉特定優勢生存至今。這場演化的壯麗史詩強調,現代鳥類實為活著的恐龍,延續著史前的生命印記。 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/139d6ce376b8 Powered by Firstory Hosting
