But some things did change over evolutionary time. Or rather, 144 things.

但是随着时间的推移，确实有些区别。或者确切的说是144处不同。

So as the cerebrum grew through evolutionary time, it got more massive but our skull didn't exactly keep up.

所以随着大脑的进化，它变得越来越大，但是我们的头骨没有跟上。

Animals come in all different sizes, but usually, over evolutionary time, each type of animal stays roughly the same size.

动物有各种不同的大小，但通常情况下，随着进化时间的推移，每种动物的大小大致相同。

The animals have spent evolutionary time honing the composition of their shell to make it deflect predators, to make it strong.

动物们花了很长的时间来进化，它们一直在锻造自己的外壳，使其更强大，并能抵挡捕食者。

But it's important to realize that all of these activities are relatively recent inventions when looked at on an evolutionary time scale.

但重要的是要认识到，从进化的时间尺度来看，所有这些活动都是相对较新的发明。

So they've been really, really successful both in terms of, like, long-scale, deep evolutionary time, but also in terms of where they live on the world, because they live basically everywhere.

所以它们已经非常非常成功了，无论是从长期的深度进化来看，还是从它们在世界上的居住地来看，因为它们基本上生活在任何地方。

But over the course of evolutionary time, both the Anomurans and the Brachyurans came closer and closer to what we think of as the " crab shape" that we know today.

但在进化过程中，Anomurans 和 Brachyurans 越来越接近我们今天所知道的“螃蟹形状” 。
