Please forgive my rather dated memory, but its been about 10 years ago that I recall a Northeastern biologist by the name of Lynn Margulius working alot in this area. At the time, I believe she was considered psuedo-fringe, perhaps due to her association with the Gaia (-10 sp) Hypothesis. She was concerned with the origins of cell organelles and the development of photosynthesis. her contention and work supported the idea that celluar components were often created outside the the cell, and through phagocytosis or whatever, assumed a symbiontic relationship within the aggressor cell. Hope this may help.
