Or are there other biological domains hiding in the shadows—missed, like the archaea were for so long, because biologists have been using the wrong tools to look?

That means leaving out the bacteria, which are ubiquitous but for whom the concept of 'species' is rather problematic, and the archaea, the third great class of Earthly life.
这意味着细菌（虽普遍存在但能否称为“物种”则备受争议）以及地球生命排在第三等级的古细菌都被排除在外。
But while bacteria reproduce rapidly, the Archaea population doubles over the course of hundreds, even thousands, of years thanks to a slower metabolism and distinct genetic structure.

As to importance, when originally identified as distinct, the archaea, too, were regarded as marginal-yet their methane-generating properties are now a factor in climate-change calculations.
至于其重要性，古菌群在最开始被认定为自成一类时，也被视为无关紧要——但是它们释放甲烷的特性现在已被纳入气候变化的考察因素。

最近，纽芬兰岛海岸的海床之下1.6千米深处取出的砂心泥中，发现了活着的细胞，其中很多是热球菌纲火球菌属的古菌。
Perhaps Archaea has been relegated to its seemingly second-class status because it is a relatively recent discovery—the separate domain was first proposed in 1977.
古生菌被归为不太重要的二等类别，或许是因为它是新近才被发现的——首次提议将古生菌作为单独的类别是在1977年。
An archaean converts DNA into proteins very differently from, say, streptococcus-in fact, protein synthesis in archaea is more similar to the human process than to bacteria.
古生菌，比如链球菌，将DNA转录成蛋白质会非常困难——实际上与细菌相比，古生菌的蛋白质合成过程与人类的蛋白质合成过程更相似。
Methane-producing archaea (methanogens) are a type of chemolithotroph that can use carbon dioxide and hydrogen to make methane without ever seeing the sun.
产甲烷古菌（methanogens）是一种化能自养生物，它能利用二氧化碳和氢合成甲烷，而不需要太阳参与。
NEW RESEARCH SHOWS THE IMPORTANCE OF ARCHAEA, ONE OF THREE DOMAINS INTO WHICH ALL LIVING THINGS ARE CLASSIFIED, FOR UNDERSTANDING ALL OF BIOLOGY.
一项最新研究显示了古生菌的重要性。为了了解所有的生物，可以将生物划分为三大类，古生菌便是这三大类中的一类生物。
