tetrapods
English: tetrapods
Chinese: 散砾石
四足动物
Examples:
1. By and large, the limbed tetrapods and near-tetrapods unearthed thus far have been sizeable beasts, around a meter long.
整体说来,目前发掘出的有肢四足动物或近四足动物,都是相当大的怪兽,体长约有一公尺。
2. For example, we know that tetrapods have lost all the bones that protect the gills in fish but that the genes that govern their formation are still present in mice, where they function differently.
举例来说,我们知道四足动物失去所有在鱼类用来保护鳃的骨头,但掌管其形成的基因仍存在于小鼠身上,担任不同的功能。
3. Further work will be needed to confirm these ideas, but the latest data demonstrate that Devonian tetrapods were more diverse than previously suspected.
要证实这想法还需要更多的证据,不过最新的资料显示,泥盆纪四足动物的多样性比之前猜想的还要高。
4. Something special happened when tetrapods first evolved a neck that prevented limbs from sprouting there.
当四足动物首次演化出颈子时,发生了某种特别的事件,阻止四肢从该处长出。
5. The earliest tetrapods were all carnivorous, so it is unlikely that, as adults, they fed much on land during the first phases of their evolution, because the only prey they would have found there were insects and other small arthropods.
最早的四足动物都是肉食性的,那时陆上的食物只有昆虫与小型节肢动物,所以成体不太可能在演化初期就以陆地做为主要的摄食处。
