  1. For each analysis we conducted 100 randomizations to determine whether the predicted number of each event type is higher or lower than expected by chance.
  2. aEvent costs are for codivergence (cospeciation), duplication (within-host speciation), sorting (extinction), and host switching, respectively.
  3. bThe number of events significantly exceeds that for randomized trees (P < 0.05).
  4. cThe number of events is significantly less than that for randomized trees (P < 0.05).
