Video Description
在一塊兩寸見方的石塊上，舒德干教授發現了一個不足兩厘米長、模糊得幾乎無法辨認的魚狀化石。它是包括我們人類在內的所有脊椎動物的「老祖宗」，這是舒德干教授在「寒武紀生物大爆發」領域的其中一個研究成果。達爾文曾對寒武紀生命大爆發感到費解，因為他在《物種起源》裡提出的觀點無法解釋為什麼這一時期生命突然大量豐富。舒德干教授在這一領域的發現被作為標誌性成果錄入多國教材。 「雲南澄江化石庫是我回國的重要原因之一，那裡有我的用武之地，那些埋藏在地下的化石，已經等待了上億年。」 「就是這樣的一個途徑，從這個微小的動物，我們把它叫皺囊蟲，然後經過古蟲動物類似的有鰓裂的東西，它有肛門了，然後就長出頭來了，最後才誕生了人類，整個故事就完整了。」
