I don't think the eukaryotic cell was that difficult a transition. Consider mixotricha paradoxa, which is, essentially, the reinvention of the eukaryotic cell at a higher level. That only one germline of "eukaryitic-like" cells survived to the present isn't really a very good argument that in the deep past there weren't several. Most gene-lines eventually go extinct.
