Whether or not all life came from the same cell is not something that is not entirely established and to be perfectly honest, I'm not an expert in early microbiology theories. Sorry..
However, certainly from the same group or very similar groups of early simplistic cellular life forums. It may be a situation where there are viruses and self-replicating forms which evolved and interacted.
But, if it makes you feel better, to say that all life arose from simple proto-cells of similar and simple types is a fair summary. In any case, they are all related.
And certainly humans and octopuses being macroscopic members of the animal kingdom would probably have a common ancestor if you go back far enough..
DOC's initial post on the subject would indicate that he thinks that the first self replicating life form was a complete cell.
