Document Summary
Intense parental care (especially maternal) care: different types of teeth. Increased brain size, slow life history (go together) Increased learning and behavioral flexibility: primate characteristics - derived, something that only evolved within our lineage, what makes primates unique. Locomotion is hindlimb dominated: pre-adaptation for bipedalism, mobile arms and shoulders, not restricted to one form of movement. Limbs also used for other activities (handling things: fine object manipulation, tool use: pre-adaptation for tool-use and manufacture, carrying, etc, diet and teeth. Lack of dietary specialization: generalized dentition, omnivores. Increased reliance on visual stimuli over olfactory cues: morphological changes in. Skull: eyes, brain, color vision, depth perception - stereoscopic vision, decreased reliance on olfaction, reduction in olfactory apparatus. Lower predation risks: costs of brains, energy, risk of starvation. Social learning and cultures, traditions, learning passed down from generation to generation: know the traits that distinguish the main branching points.
