FACIAL DISPLAYS. “Primates, especially anthropoids, are dependent upon visual communication more so than most other mammalian orders and this often occurs via facial displays. Indeed, the evolution of trichromatic vision and the high visual acuity within Old World primates have been linked at least in part to their elaborate use of visual communication, including skin and fur pigmentation and facial displays.”
