Ten years ago in the early days of genome sequencing, researchers scoured the genomes of 580 bacterial and
archaeal species for large genes.
The lineages of these groups are not restricted to extreme habitats, as was once thought common for
archaeal species; rather, archaea are widespread and occur in all thinkable environments on Earth, where they can make up substantial portions of the microbial biomass.

The putative
archaeal host existed in a stable symbiotic relationship with one or more bacterial
species, with the capacity for both gene and lipid exchange between
species.
