Document Summary
Many will go extinct in 50 years. To understand any organism you must compare its anatomy and behaviour with that of other, closely related species. Lemurs progressed earlier and did not become anthropoids. The species that represent final evolutionary stages become extinct. Long gestation period followed by live birth, Ability to maintain a constant internal body. They have received several ancestral mammalian traits that some other mammals have lost over time. Primates cannot be defined by one or even a few traits they share in common. They use color vision (nocturnal primates do not). Primates have four kinds of teeth: incisors and canines: biting and cutting, premolars and molars: for chewing and grinding. Primates found adaptive niche and their food in trees. This dietary shift enhanced a general trend in omnivores. Increased reliance on vision, coupled with grasping hands/feet. 4 kinds of teeth: 2. 1. 2. 3 pattern: 32 teeth. There is a lack of dietary specialization because of the size/shape of teeth.
