Document Summary
Opening at the front of the mouth that provides access to the vomeronasal organ or. Jacobsen"s organ (chemical sensing), also known as wet nose. But there are exceptions (all but one genus are diurnal) The important division is not in nose morphology, but in biogeography. Catarrhini (only in africa and asia, old world) But monkeys is not a meaningful group in terms of evolution. Some monkeys are more closely related to apes than other monkeys. Sitting pads (tail is used as a balancing object) Has more range of motion than a regular tail. Similar in age and even more recent than subfossil lemurs. One of the last primates to go extinct. Probably humans played a role in its extinction, but unclear. A large group breaks up into subgroups (ie for foraging subgroups often of the same sex) Not very dimorphic, due to the 1m-1f group composition. Extremely prehensile tail, most acrobatic of the atelines.
