 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.
