I just think it’s a framing problem. In bacteria and archaea(particularly in the early periods) the genes themselves are what were impacted by natural selection and they would propegate between species based on the gene’s fitness alone. “Ancestor” is a bit of a misnomer and it’s very hard to ever say you’ve developed a timeline.
Continuously adding the Evolutions pile of evidence is a good thing
