5  MYA  Lived in N. America and Europe  Its fossils first discovered in Montana  Member of a Genus called the plesiadapiforms

6  About 50 MYA, pretty soon after the dinosaurs go extinct, there is an explosion in the number of primate species—about 6000 species arise.  The 200 species now living are the what remains of this differentiation. (Lewin 2005:64)

28  Limbs and locomotion: › Erect or semi-erect posture › Generalized limb structure allows a variety of locomotive behaviors.

29

30  Limbs and locomotion: › Prehensile hands and feet.  Five digits  Opposable thumbs and big toes  Fingernail instead of claws

31 SLOW LORIS

32  Generalized diet and teeth

33  The senses and the brain: › Color vision (diurnal primates only)

34

35

36  The senses and the brain: › Stereoscopic vision (depth perception)  Eyes to the front  Visual information from each eye transmitted to visual centers in both hemispheres in the brain  Visual information processed by specialized brain structures

37 TARSIER

38  The senses and the brain: › Large and complex brains  Visual information processing  Large areas involved with the hand

39  Maturation, Learning and Behavior › Long gestation › Single births instead of litters › Delayed maturation › Tendency to live in mixed-age groups › Dependence on learned behavior
