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

古菌和细菌都是原，因为它们的 DNA 中没有细胞，细胞位于细胞质中。

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

原缺乏磷，所以它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.

原不是通过一系列渐的化步骤逐渐变成真的。

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

在这之前，所有的细胞都是原：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，原化成更复杂的真。

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

大约在这个时期，像细菌这样的原开始在地球上定居。

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

真更为复杂且体型较大，而原则体型较小且结构较为简单。

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

它们看起来很像细菌——原——但古细菌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.

许多学家告诉我， 从原到真的跨越是一个巨大的难题，就像复杂命的出现那样。

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

大约 37 亿年前，称为原的单细胞微首先在我们的星球上化。

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

原是没有细胞的简单细胞，如细菌。

Prokaryotes are going to be way smaller then eukaryotes.

原细胞要比真细胞小得多。

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

在原或细菌中， 我们也可以包括古菌，它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.

真和原是两种基本类型的细胞，它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和原。

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

但在原中，它同样重要。

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，无论是真细胞还是原细胞，都正好处于这样一个理想的范围内。

But also it's important in prokaryotes.

但它在原中也同样重要。

Bacteria are going to be these single cell prokaryotes.

细菌将是这些单细胞原。
