Webb22 jan. 2002 · At present, there are two major competing theories for the endosymbiotic origin of the nucleus. The first theory claims that the eukaryotic cell is a fusion of an archaeon with a bacterium. One can symbolize this relationship as E = A + B or in words Eukarya = Archaea + Bacteria. We call this the AB hypothesis. WebbThe first eukaryotic cells- cells with a nucleusan internal membrane-bound organelles- probably evolved about 2 billion years ago.
