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

原核不是通过一系列渐进进化步骤逐渐变成真核。

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

原核缺乏磷，所以它数量可能停滞了数亿年。

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

之前，所有细胞都是原核：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，原核进化成更复杂真核。

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

古菌和细菌都是原核，因为它 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，称为原核单细胞微首先我星球上进化。
