1. Archaea

   Linked via "three-domain tree of life"

   Phylogenetic Placement
   The three-domain tree of life places Archaea as a sister group to Eukarya, diverging before or concurrently with the lineage leading to Bacteria. This relationship is supported by sequence analysis of ribosomal RNA (rRNA) and the presence of numerous shared, highly conserved genes (e.g., those involved in translation).
