| Description: A partial phylogenetic tree of the mammals shows examples of monophyletic groups. Elephants, manatees, and hyraxes form one monophyletic group, tapirs and rhinoceroses form another, and the group of tapirs, rhinoceroses, and horses form a third. However, pachyderms– elephants, rhinoceroses, and hippopotamusesâ€â€Âare not a monophyletic group. Adapted from Murphy et al. (2001).
