The PEDIGREE of
(NN), a Cell Nucleus

     (poss. began as SYMBIOTIC organelle)

    Note: The relationship among the three Domains of life (Eubacteria, Archaeota, and Eukaryotea) is unclear. Here we show one theory, that Eukaryotes began with a bacterium engulfing an archaeon, the latter becoming cell nucleus.


 "Child(ren)":       (NN), a Nucleated Cell
 poss. "Partner(s)":       (NN), a thermophilic Bacterium   ;   (NN), a very special Archaeote
