But maybe you can explain archaea, and eukaryotes, Alice.

也许你应该解释一下古生菌和真核生物。

They are the closest relatives to eukaryotes, according to recent DNA analyses.

根据最近的DNA分析，它们是与真核生物最接近的亲属。

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

原核生物不是通过一系列渐进的进化步骤逐渐变成真核生物的。

Such modern intermediates might have been the end product for primeval eukaryotes.

这些现代中间体可能是原始真核生物的终产品。

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

大约 10 亿年后，原核生物进化成更复杂的真核生物。

We have isolated around 30 or 40 strains already of unicellular eukaryotes.

Malavin：我们已经分离出大约 30 或 40 株单细胞真核生物。

Another  billion years passed before eukaryotes developed into multicellular organisms, which eventually  exploded into diverse kingdoms of complex life.

又过了 10 亿年，真核生物才发展成为多细胞生物，最终发展成复杂生命的不同王国。

For that reason, palaeontologists have used the compounds as a biomarker for the presence of eukaryotes in ancient rocks.

因此，古生物学家使用这些化合物作为古岩石中真核生物存在的生物标志物。

He said that while fungi are one of the more diverse groups of eukaryotes today, their ancient fossil record is " very scarce" .

他说，虽然真菌是当今最多样化的真核生物群体之一，但关于它们的古老化石记录" 非常稀少" 。

The molecules are 1.6 billion years old and hint that eukaryotes were abundant and widespread much longer ago than earlier biochemical evidence had suggested.

这些分子有16亿年的历史，暗示着早在之前的生物化学证据所显示的时间之前，真核生物就已经广泛存在和繁殖了。
