    AnotáciaA novel hypothesis for the origin of eukaryotes is presented. It is assumed that the universal ancestor was bounded by two membranes of heterochiral lipid composition. We propose that the pre-karyote (the hypothetical host entity for alpha-proteobacteria), though sharing a common ancestor with Archaea, was bounded by two membranes. The hypothesis suggests that an a-proteo bacterial symbiont was enclosed in the pre-karyote intermembrane space. In this view, the eukaryotic nuclear membrane and endomembrane system arose from the pre-karyote inner membrane while the eukaryotic plasma membrane arose from the pre-karyote outer membrane. The outlined scenario agrees with the view that engulfment of an alpha-proteobacterial cell by a host entity and its transformation to a mitochondrion was the driving force leading to the appearance of the first eukaryotic cell. The hypothesis seems to be consistent with the pre-cell theory, theory of membrane heredity, and the phagocytosis-late scenario.
