 The great apes with the family Hylobatidae of gibbons form the superfamily Hominoidea of apes.Apes, in turn, belong to the primate order (>400 species), along with the Old World monkeys, the New World monkeys, and others.Data from both mitochondrial DNA (mtDNA) and nuclear DNA (nDNA) indicate that primates belong to the group of Euarchontoglires, together with Rodentia, Lagomorpha, Dermoptera, and Scandentia.
