And genes acquired from bacteria appear to have played an important role in forming major taxa of archaea, according to a phylogenetic analysis of more than 25,000 archaeal gene families. The study, ...

Since the late 1980s, all life forms have been split into three groups on the phylogenetic tree of life: bacteria, archaea, and eukaryotes. Eukaryotes and archaea have long been considered “sister ...
