Even if the genes haven't actually jumped they can cause problems if you
don't know what you're sequencing.  Unlike morphology, it's not hard to be
mistaken about the source of DNA.  Visual examination of an alignment and
BLAST searches are two good ways to check for anomalous sequences, but
perhaps the most important thing is to remember that the fact that the
latest analysis produces a novel result is not proof that previous work was
wrong - the error may lie in the new work.
