earliest cercopithecoids, or Old World monkeys, are African in origin
and date to the early Miocene. Extant cercopithecoids are more
taxonomically diverse than hominoids, and are the most widespread of all
nonhuman primates. While initially viewed as primitive catarrhines,
cercopithecoids are now appreciated as being quite derived and
specialized in their own regard. Compared to hominoids, cercopithecoids
have reduced or absent maxillary sinuses and relatively narrow nasal
aperture. Cercopithecoids have bilophodont lower molars, long trunks,
narrow elbow joints, and relatively long olecranon processes. Many
members have a long tail.</p>
