Would this then be evidence of abiogenesis occurring more than once, or do you mean something else?
It could be - there is still so much we don't know.
It would be interesting to see what they get from sequencing the genome of these new things.

I think it's unlikely that life only started once and that everything evolved from that first single cell (seems to Adam and Eve to me). I'm sure life occurred several times, some lineages died out, some combined (like ancient archea and bacteria fusing to become eukaryotes, or modern bacteria swapping plasmids).
If that's the case, we should see that the genetic code of the organelles is significantly different to the code of the nucleus. My understanding is that this isn't the case.

What ever the truth is, it's probably way more complicated than we think (and ultimately unknowable, it will just be hypotheses and conjecture)
True, it will turn out to be quite complicated, I think, but I think we'll be able to figure out enough to get a very good idea of what actually happened.
