Document Summary

Arboreal mammals, dietary plasticity, highest amount of parental investment. Vertical tendency in human ancestor was preadaptation for bipedalism. Dermal ridges on hands and feet - fingertips. Finger nails are reduced claws and help grasping. Color vision (hunt insects and determine which fruits are good to eat) Strepsirhines (wet nosed primates): have rhinarium and better smell. Humans and apes and old world monkeys formula: 2. 1. 2. 3. Monkeys have a bilophodont pattern (2 high ridges) Humans have 5 low cusps that form a y-5 pattern. Prosimians (strepsirhines and tarsiers) have a tooth comb. Small canines in species practicing long term pair bonds. Canine-premolar honing complex: canines with gaps in the mouth; when animal closes mouth, it sharpens the canines. Primates usually have one offspring at a time. Mothers care for child for a long time. Primates fall just below average size compared to others.
