Zusammenfassung: | <jats:p> Numerous biomolecular studies from the past 20 years have indicated that the large African monkeys <jats:italic>Papio</jats:italic> , <jats:italic>Theropithecus</jats:italic> , and <jats:italic>Mandrillus</jats:italic> have a diphyletic relationship with different species groups of mangabeys. According to the results of these studies, mandrills and drills ( <jats:italic>Mandrillus</jats:italic> ) are most closely related to the <jats:italic>torquatus</jats:italic> – <jats:italic>galeritus</jats:italic> group of mangabeys placed in the genus <jats:italic>Cercocebus</jats:italic> , whereas baboons ( <jats:italic>Papio</jats:italic> ) and geladas ( <jats:italic>Theropithecus</jats:italic> ) are most closely related to the <jats:italic>albigena</jats:italic> – <jats:italic>aterrimus</jats:italic> mangabeys, now commonly placed in the genus <jats:italic>Lophocebus</jats:italic> . However, there has been very little morphological evidence linking mandrills on the one hand and baboons and geladas on the other with different groups of mangabeys. In a study of mangabey locomotion and skeletal anatomy, we have identified features of the postcranial skeleton and the dentition that support the molecular phylogeny and clearly link mandrills with <jats:italic>Cercocebus</jats:italic> and <jats:italic>Papio</jats:italic> with <jats:italic>Lophocebus</jats:italic> . Moreover, the features linking <jats:italic>Cercocebus</jats:italic> and <jats:italic>Mandrillus</jats:italic> accord with ecological studies of these species indicating that these two genera are a cryptic clade characterized by unique adaptations for gleaning insects, hard nuts, and seeds from the forest floor. </jats:p> |
