In reality , though , almost all living things are unicellular , and with good reason .

By searching for genetic sequences similar to rega in the burgeoning databases of genes that now exist , they found one in a unicellular alga called chlamydomonas reinhardtii .

在搜索了不断扩充的数据库中海量的基因之后，他们在一种单细胞藻类衣藻chlamydomonasreinhardtii中发现了一段和rega类似的基因序列。

This remarkable change at a planetary scale - orchestrated by unicellular beings - did something else that allowed complex life to thrive on earth 's surface .

这种发生在整个行星中的显著改变由单细胞生物开始确实让更为复杂的生命体在地球上成长繁荣起来。
