Phylogeny of African monkeys based upon mitochondrial 12S rRNA sequences

The suborder Anthropoidea of the primates has traditionally been divided in three superfamilies: the Hominoidea (apes and humans) and the Cercopithecoidea (Old World monkeys), together comprising the infraorder Catarrhini, and the Ceboidea (New World monkeys) belonging to the infraorder Platyrrhini.We have sequenced an approximately 390-base-pair part of the mitochondrial 12S rRNA gene for 26 species of the major groups of African monkeys and apes and constructed an extensive phylogeny based upon DNA evidence. Not only is this phylogeny of great importance in classification of African guenons, but it also suggests rearrangements in traditional monkey taxonomy and evolution. Baboons and mandrills were found to be not directly related, while we could confirm that the known four superspecies of mangabeys do not form a monophyletic group, but should be separated into two genera, one clustering with baboons and the other with mandrills. Patas monkeys are clearly related to members of the genus Cercopithecus despite their divergence in build and habitat, while the talapoin falls outside the Cercopithecus clade (including the patas monkey).
