1. The creatures are single-celled organisms called archaea which are able to thrive in an ecosystem where sunlight never penetrates.
   这些可以在没有阳光的环境里茁壮生长的单细胞生物被称为古细菌。
2. Although similar in size and shape to bacteria, genetic analysis reeals that archaea are actually more closely related to humans and other eukaryotes.
   古细菌尽管在大小和形状上与细菌相似，但遗传分析表明它们实际上更接近于人类和其它真核生物。
