Archaea and bacteria are prokaryotes, and because they do not have nuclei in their DNA, it is located in their cytoplasm.

古生和都是原核生，们的 DNA 中没有胞核，胞核位于胞质中。

Prokaryotes were starved for P, so their population likely stalled for hundreds of millions of years.

原核生缺乏磷，所以们的数量可能停滞了数亿年。

Prokaryotes didn't gradually morph into eukaryotes through a bunch of gradual evolutionary steps.

原核生不是通过一系列渐进的进化步骤逐渐变成真核生的。

Up until this point, all cells were prokaryotes: simple bags of stuff without any division of labor going on inside.

在之前，所有的胞都是原核生：里面只有质，没有任何分工。

Roughly one billion years later, prokaryotes evolved into more complicated eukaryotes.

大约 10 亿年后，原核生进化成更复杂的真核生。

Some time around here Prokaryotes like bacteria begin colonizing the planet.

大约在个时期，像样的原核生开始在地球上定居。

Eukaryotes are more complex and larger, while prokaryotes are smaller and less complex.

真核生更复杂且体型较大，而原核生则体型较小且结构较简单。

They look a lot like bacteria–prokaryotes–but Archaea have unique internal machinery.

们看起来很像——原核生——但古具有独特的内部机制。

So a lot of biologists tell me the big difficult leap is from the prokaryotes to the eukaryotes, so like the complex life.

许多生学家告诉我， 从原核生到真核生的跨越是一个巨大的难题，就像复杂生命的出现那样。

About 3.7 billion years ago, single-celled  microbes, called prokaryotes, first evolved on our planet.

大约 37 亿年前，称原核生的单胞微生首先在我们的星球上进化。

Prokaryotes are simpler cells without a nucleus, such as bacteria.

原核生是没有胞核的简单胞，如。

Prokaryotes are going to be way smaller then eukaryotes.

原核胞要比真核胞小得多。

In prokaryotes or in bacteria, and we could throw archaea on with this as well, they show what's called horizontal acquisition.

在原核生或中， 我们也可以包括古，们展示了所谓的水平获得。

Eukaryotes and prokaryotes are two basic types of cells that differ mainly in their internal structures.

真核生和原核生是两种基本类型的胞，们的主要区别在于内部结构。

The next two words are eukaryotes and prokaryotes.

接下来的两个词是真核生和原核生。

But it's just as important in prokaryotes as it is in us.

但在原核生中，同样重要。

But it looks like life which is going to be eukaryotes and prokaryotes are going to be right in this kind of a sweet spot.

但看起来，无论是真核胞还是原核胞，都正好处于样一个理想的范围内。

But also it's important in prokaryotes.

但在原核生中也同样重要。

Bacteria are going to be these single cell prokaryotes.

将是些单胞原核生。
