mandrills

Given that we now have dog-faced monkeys variously scattered about a phylogenetic tree that also includes shorter-faced baboon-mangabeys, drill-mangabeys and the kipunji, you should now be wondering about the polarity and evolution of the long muzzle and large body size seen in mandrills, baboons and geladas.

The mandrills are another species of baboon who inhabit this region.

These were the hideous "mandrills," as we could tell by their great swollen cheeks, of purple and scarlet colour, that shone conspicuously under the light of our fire.

Also, red signifies male dominance in non-human primates, such as mandrills and gelada baboons, and other primates linked to human beings.

Drill-mangabeys, drills and mandrills are also united by particularly large, rounded posterior premolars, a robust ilium, a reduced gluteal tuberosity on the femur, sharp borders to the margins of the patellar groove, and other characters.

In the humerus, drill-mangabeys, drills and mandrills share a notably broad deltoid plane, a proximally extended supinator crest, a broad flange for the brachialis, and a narrow olecranon process with a deep lateral ridge, and there are also characters in the radius and ulna that unite these monkeys to the exclusion of their close relatives.

Drill-mangabeys, drills and mandrills search manually through rotten wood and leaf litter, consuming hard nuts and seeds, and audibly cracking them with their large teeth.

Skeletal and dental morphology supports diphyletic origin of baboons and mandrills.

However, molecular studies have consistently found mangabeys to be diphyletic, with the six terrestrial mangabey species forming a clade with drills and mandrills (and with macaques too in some studies), and the two arboreal mangabeys forming a clade with baboons and geladas.
