人们早就知道鸟类是属于恐龙家族的一员,但是如何解释恐龙家族是怎样突然之间长出翅膀的,这却并不容易。不过,最近研究者通过一种技术能够清楚地了解古代类鸟生物的软组织结构,从而能够更加详细地描绘恐龙最终飞向蓝天的过程。很不幸,恐龙肉在能够成为化石之前就会被腐化掉,因此我们所具有的恐龙化石仅限于牙齿、骨骼,并根据这些有限的线索去猜想恐龙可能的样子。其中一个鲜活的例子 It has long been known that birds belong to the dinosaur family, but it is not easy to explain how dinosaurs grow their wings suddenly. However, researchers have recently been able to clearly understand the soft tissue structure of ancient bird-like creatures through a technique that can describe in more detail the ultimate dinosaur’s migration to the sky. Unfortunately, dinosaur flesh is corrupted before it can become a fossil, so the dinosaur fossils we have are limited to teeth and bones, and based on these limited clues we can guess what a dinosaur might look like.
