  4. The Endosymbiotic Theory worksheet from IUPUI presents a nice table summarizing some of the imporant similarities among bacteria, chloroplasts, and mitichondria then continues and summarizes Lyn Margulis' theory and the logic behind it.
  5. Endosymbiosis: Lynn Margulis from University California Berkeley provides a historical perspectice on the theory and summarizes the DNA evidence in an easy to comprehend way.
  6. On the Origin of Eukaryotes an essay by Carl Zimmer from the Science series in honor of the Year of Darwin presents an excellent summary along with some of the latest competing hypotheses concerning the origin of eukaryotes - we may be more of a conglomerate of prokaryotes than we thought and our understanding of the domains of life may change!
