Roy Hanfling Howard Bloom, in the book “Global Brain” lays it out well. What eukaryotes did was to absorb other bacteria and use them for more complex purposes. The bacteria absorbed into the eukaryote each served a useful function, with mitochondria being the “energizer” of the cells. Basically colonies formed to serve a more centralized purpose, and began replicating.
