Document Summary
Dominant females mate with group males and subordinate mainly with extra group males. When infants of the subordinate = born at around the same time as the dominant female, then the dominant female would direct aggression towards the subordinate"s infant (tho not when they are born at separate times) Neocortex size relates to social complexity and tactical deception (machiaveillian intelligence) Distinctive cognitive abilities of primates are based on expedience something that requires the ability to gauge whether cooperative or competitive tactics are called for, and adjust for one"s behavior accordingly. Mutual cooperation stimulates the reward centers of the brain (in neocortex) Four things distinguish primates from other animals: locomotor, neural and sensory, feeding and life histories. Associated with their unusual mode of suspensory locomotion. Allometric scaling allows us to compare absolute and relative effects and determine specialized adaptations. Brain to body size ratios: humans > dolphins > other primates.
