By the term systematic affinity is meant, the general resemblance between species in structure and constitution.

This is because tectonic plates on our planet repeatedly recycle the surface, burying evidence from before the time life formed.

This type of rock forms in abundance on Earth only thanks to our planet's liquid water and active plate tectonics; the moon lacks both.

这种岩石在地球上大量存在，完全得益于我们星球上的和活跃的块；而月球上则缺乏这两样东西。

With the end finished product there's no difference between a human construction and a robotic construction except the robotic construction is overall a little more accurate.

对于最终成品，人工和机器人之间没有区别，只是机器人总体上更准确一些。

Iceland sits on a tectonic plate boundary that continually splits apart, pushing North America and Eurasia away from each other along the line of the Mid-Atlantic Ridge.

冰岛位于不断分裂的块边界上，沿着大西洋中脊线将北美和欧亚大陆分开。

On this orange, I've split the peel into different pieces, each of which can move independently, just as the tectonic plates are arranged on the Earth.

在这个橘子上，我把果皮分成不同的部分，每个部分都可以独立移动，就像地球上的块一样。

Now, Iceland sits on a tectonic plate boundary between the North Atlantic and Arctic Oceans, and that plate continually splits farther apart, pushing North America and Europe farther apart.

现在，冰岛位于北大西洋和北冰洋之间的块边界上，该块不断分裂，将北美和欧洲推得越来越远。

Don't let us hamper ourselves by despising those brains comparable in volume, as well as in construction, to wrens' eggs, but let us at once enter fully into the object of our conference.

不要让我们轻视那些在体积和上与鹪鹩蛋相当的大脑而束缚自己，而是让我们立即完全进入我们会议的目标。
