title: Eukaryotic evolution: the importance of being archaebacterial.
abstract: Approximately half of all eukaryotic genes show signs of prokaryotic origin. Genes derived from eubacteria are more abundant than those from archaebacteria, but the latter are functionally more important. This supports archaebacteria as founding ancestors of the eukaryotic nucleus.
