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

原核物缺乏磷，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.

原核物不通过一系列渐进的进化步骤逐渐变成真核物的。

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

在这之前，所有的细胞原核物：里面只有物质，没有任何。

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

古和细原核物，因为它们的 DNA 中没有细胞核，细胞核位于细胞质中。

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

大约 37 亿年前，称为原核物的单细胞微物首先在我们的星球上进化。

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

大约 10 亿年后，原核物进化成更复杂的真核物。

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

大约在这个时期，像细这样的原核物开始在地球上定居。

The next two words are eukaryotes and prokaryotes.

接下来的两个词真核物和原核物。

Prokaryotes are going to be way smaller then eukaryotes.

原核细胞要比真核细胞小得多。

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

它们看起来很像细——原核物——但古细具有独特的内部机制。

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

真核物和原核物两种基本类型的细胞，它们的主要区别在于内部结构。

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

原核物没有细胞核的简单细胞，如细。

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

真核物更为复杂且体型较大，而原核物则体型较小且结构较为简单。

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

但在原核物中，它同样重要。

But also it's important in prokaryotes.

但它在原核物中也同样重要。

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

在原核物或细中， 我们也可以包括古，它们展示了所谓的水平获得。

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

许多物学家告诉我， 从原核物到真核物的跨越一个巨大的难题，就像复杂命的出现那样。

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，无论真核细胞还原核细胞，正好处于这样一个理想的范围内。

Bacteria are going to be these single cell prokaryotes.

细将这些单细胞原核物。
