I am not too sure we know how Cyanobacteria arose (I did my Ph.D. on them) nor how mitochondria arose. Given how rampant horizontal gene transfer is I doubt we ever will.
I think the most interest question in this early biology is why LUCA is so complex [1]. We have a massive gap between abiotic processes and the first organism we know anything about. What happened.
