Phylogeny of Primates (human, chimpanzee, orangutan, macaque), Laurasiatheria (canine, horse, bovine) and Rodentia (mouse, rat) inferred from (A) a DCJ distance and (B) a breakpoint distance matrix tree. Values above branches show the number of times that the clade defined by that node was supported by 1000 jackknife trees. Values below branches show number of genome rearrangement events. Opossum is the outgroup.
