I think perhaps Nick Lane could explain a lot to most people. The jump from prokaryote to eukaryote happened just once, after around 1.5 billion years of prokaryote life -- and in spite of ample opportunity, it has never happened again, with countless zillions of bacteria and archaea swarming everywhere for 2 billion years following the event.I doubt if Nick Lane can tell me anything new about origin of life. I pursue all report on this subject. Our question is about Eubacterial Adam and Eve. Was it just one or it came about in the way humans evolved (i.e., not ascribing origin to just one pair, but each step putting in some change in DNA)?
Did you watch this short video, in the above post?it's not what biologists say.
"There are multiple, independent lines of evidence to support the hypothesis that eukaryotes evolved from an endosymbiotic event between an ancient archaean cell and an ancient aerobic bacterium:"

It only happened once in the entire history of life on earth, and never happened again after that. It's one of the great mysteries. A virtually impossible event, but it happened, or there'd be no higher life on earth. It's why the chance of higher life on other worlds is regarded as extremely low, although there may be a reasonable chance of bacterial life.
That's why scientists are looking for a better explanation than endosymbiosis for the origin of eukaryotes, but they haven't found one and most agree that a single one-off endosymbiosis 'quantum leap' event is the best explanation
Lane is also at the cutting edge of research of origin of life (abiogenesis), but which is a different subject to the later origin of the eukaryotic cell.
I'm sure if you research 'origin of eukaryotes' you will find confirmation of what I've said above. I'm sorry but it has zero to do with abiogenesis or Adam and Eve -- and it's not about DNA or mutation either, so ...
