2025 biology talkshow: 自然界線與人為分類-物種概念的探討 (選修生物4)

探討物種概念的複雜性與多樣性，指出「物種」並非自然界中絕對存在的實體，而是人類為理解與分類生命而建構的工具。解釋生物學物種概念 (BSC) 和系統發生學物種概念 (PSC) 等主流定義，並闡述這些概念的適用範圍與局限性。透過環物種現象和跨屬雜交等案例，揭示自然界如何挑戰既有分類界線，強調物種邊界更像是連續光譜而非固定分割。最終總結「物種」雖非完美，卻是人類理解生物多樣性與演化脈絡的重要且必要的工具。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 https://g.co/gemini/share/7f26f982cc08址 Powered by Firstory Hosting
