• Carl Woese

  Woese stated that eukaryotes and Archaea are more closely related to each other than either is to eubacteria
• Carl Woese

  Evidence:

  small subunit ribosomal RNA (ssrRNA) - main research

  Sequences of amino acids in DNA/RNA polymerase

  Cell wall/membrane composition

  Antibiotic sensitivity
• Eubacteria & Archaea are prokaryotes (no membrane-bound organelles)
• Eukaryotes - animals, plants, fungi, protoctists
