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

物不是通过一系列渐进进化步骤逐渐变成真物。

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

物缺乏磷，所以它们数量可能停了数亿年。

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

在这之前，所有细胞都是物：里面只有物质，没有任何分工。

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

大约 10 亿年后，物进化成更复杂真物。

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

在这附近某个时候，像细菌这样物开始在地球上殖民。

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

古菌和细菌都是物，因为它们 DNA 中没有细胞，细胞位于细胞质中。

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

大约 37 亿年前，称为物单细胞微物首先在我们星球上进化。
