2025 biology talkshow : 恐龍滅絕後的巨鳥霸主
from 雷比特生物空中講 · host 雷比特老師
探討恐龍滅絕後，新生代時期在全球各地崛起的三種巨型鳥類。詳細介紹南美洲的駭鳥（恐鳥科），牠們是兇猛的掠食者，以其斧劈式攻擊的喙和高速奔跑的能力稱霸一方，最終因氣候變遷和與北美掠食者的競爭而滅絕。接著，討論北半球的加斯頓鳥，儘管最初被認為是掠食者，但化學與足跡證據表明牠們是植食性鳥類。最後介紹澳洲的馳鳥科（雷鳥），牠們是與雁形目親緣關係較近的巨型植食者，喙部如同螺栓剪般強大，其滅絕則與氣候變遷和人類活動有關。 聽完後可以自己進行線上測驗，檢視學習成效喔~(需要登入gemini) 測驗網址 https://g.co/gemini/share/2a29da0606aa Powered by Firstory Hosting
