Each spring there were new little spiders hatching out to take the place of the old.

每年春天都有新的小蜘蛛出世代替老的。

You see the chicks here... there’s five chicks and two eggs and the newest chick underneath here is just hatching out right as we speak.

你看所有的雏鸟都在这儿...有五只雏鸟和两个蛋，下面的刚出生的雏鸟就在我们说话的当儿刚刚孵出来的。

If we compare giant dinos hatching out of very small eggs to a mammal like an African elephant, we see much greater size changes in dinosaurs from newborns to adults than we see in most mammals.

如果我们将从非常小的蛋孵化出来的巨型恐龙与像非洲象这样的哺乳动物进行比较，我们会发现恐龙从新生儿到成年的体型变化比我们在大多数哺乳动物身上看到的要大得多。
