And so my work, really, is trying to understand the character of that Mesozoic radiation compared to the Cenozoic radiation to see what mysteries we can understand from dinosaurs and from other animals about what life on drifting continents really can tell us about evolution.
所以我的工作是试着找出 中生代和新生代时期 各生活着什么样的生物， 然后看看是否能从恐龙和其它动物上 找到关于大陆漂移过程中 生物进化的奥秘。
