Travel benefit on ground, seeing over grass for predator and resources. Persistence hunting and efficient long distance travel. Intelligence (learning, memory, info processing): problem solving capacity reasoning by homology / comparative study: what do primates and mammals tell us about brain size & intelligence. Technical intelligence: as old as 2. 5 mya. Culture: technological and behavioral, even in chimps (sticks vs.
