剧中角色 (鸡): 我是只鸡,我的祖先可以追溯到强大的霸王龙!鸟类其实就是小型恐龙,经过数百万年的进化而来。 Molly Bloom: 今天的节目将讨论鸟类与恐龙之间的关系,鸟类实际上是活着的恐龙。 Siddharth: 我从小就对恐龙和鸟类感兴趣,通过阅读和观鸟,我对它们有了更深入的了解。我发现鸟类是恐龙这一事实让我对恐龙有了新的认识。 Jingmai O'Connor: 鸟类和恐龙有很多相似之处,特别是与兽脚亚目恐龙。但鸟类也有一些独特的特征,例如飞行能力。鸟类和非鸟类恐龙曾经共存,直到白垩纪-古近纪灭绝事件。并非所有鸟类都幸存下来,但一些鸟类存活了下来,这可能是因为它们快速生长、高新陈代谢率和高效的消化系统。我们仍在研究鸟类与哪种非鸟类恐龙关系最近,以及是什么让某些鸟类在灭绝事件中幸存下来。最近在中国发现的侏罗纪鸟类化石是一个令人兴奋的发现,它将鸟类的起源时间推得更早。对鸟类的研究让我更加欣赏它们,并能更好地理解与它们有亲缘关系的恐龙。
