Candida is a type of fungi, a single celled member of the yeast family.

念珠菌是种真菌，是酵母家族的单成员。

Bacteria are these little, mostly single celled organisms, but they're fairly complex.

菌是这类小的生物，大多数为单生物，但它的结构相当复杂。

If we could somehow go back through time, meeting  every ancestor along the way from early animals to single celled microbes, all the way back to  something so simple, it can copy itself using only chemical reactions.

如能够以某种方式穿越时间，路上遇见从早期动物到单生物的每位祖先，直追溯到某个极其简单、仅凭化学反应就能自复制的存在。

Life on earth has existed for 4 billion  years, mostly as single celled organisms until some 540 million years ago the Cambrian  explosion heralded the age of animals.

地球上的生命已经存在了40亿年，大多数时候都是单生物，直到大约5.4亿年前的寒武纪大爆发才迎来了动物的时代。

In other words, we use communication to sync single celled organisms with their environment and coordinate activities in eukaryotic cells.

换句话说，利用通信来使单生物与其环境同步，并在真核中协调活动。

That's got a rather strange name, it's celled The Arretsa Centre — that's spelled A-R-R-E-T-S-A.

名字挺奇怪的，叫做Arretsa中心，A-R-R-E-T-S-A这么拼。

That's what single celled things like bacteria do.

这就是像菌这样的单生物所做的事情。
