Document Summary
Objective 1: describe the structural adaptations that primates have for arboreal life. A. limbs limbs with five highly flexible digits. B. opposable digit (thumb or toe) allows grasping. Color b. stereoscopic 3-d; depth perception, etc. Objective 2: describe and reconstruct the cladogram for primate evolution (fig. Objective 3: list and give representative examples of the three suborders of primates (knowledge/comprehension) Objective 4: distinguish among anthropoids, hominoids, and hominins (knowledge/comprehension) Anthropoids: new world + old world + hominoids (excludes suborder prosimii and tarsiiformes); size of brain is significant difference. Objective 5: list and describe differences between old world and new world monkeys (knowledge/comprehension) Comparison of old world and new world monkeys. Old world - no prehensile tail: new world - prehensile tail: capable of wrapping around branching and serving as fifth limbs. A. gibbons and orangutans tree dwellers; can brachiate (swing in trees) Chimpanzees and gorillas have long arms, but use them to assist in quadrupedal walking (knuckle walking)
