这些羊膜动物 - these creatures could colonize the drier land
能够以两栖动物无法做到的方式 - in a way that amphibians could not.
在干旱的土地上繁衍 - And from this one common ancestor,
从这一共同祖先开始 - all mammals, reptiles, birds,
所有哺乳动物、爬行动物、鸟类 - and dinosaurs would descend.
以及恐龙都将发展而来 - Sixty million years after the evolution of the amniotic egg,
进化出蛋之后6000万年
And from this one common ancestor, 从这一共同祖先开始
