We now have these amazing tools to allow us to explore the unseen world -- things like deep sequencing, which allow us to do much more than just skim the surface and look at individual genomes from a particular species, but to look at entire metagenomes, the communities of teeming microorganisms in, on and around us and to document all of the genetic information in these species.
我们现在有些很了不起的工具 来帮助我们探索未知世界， 像基因深度测序， 可以让我们不只是停留在表面 来看自某个特定物种的独立基因组， 而是研究整个基因组-- 我们身体里面和周边无处不在的微生物群落， 并且记录下这些物种的遗传信息。
