The PEDIGREE of
Last Universal Ancestor of Present Life

 
     (Life based on Dna & Protein); (there is some evidence, e.g. very different cell walls and Dna replicases, that the split between Bacteria and Archaeota was very early, though after the development of the Genetic Code)

 "Child(ren)":       poss. Archaeota Domain   ;   poss. viruses   ;  poss.   Proto-Bacteria   ;   Domain of Archaeota   ;   Empire of Life (Terra-Hydro Model)   ;   Empire of Life (Eight Kingdom Model)
 poss. "Partner(s)":       Last Universal Common Ancestor (LUCA)
