Would you say that transduction (bacteriophages) and true conjugation are more likely than transformation then? That surprises me, but my opinions are about 10 years old. I just tried looking up current work, but everyone is all gay about what's happening in eukaryotes now, and that
is mostly conjugation as I understand it.
