1. 4. Brain
   1. the mammalian brain
      1. the primate version of the mammal brain
      2. basic principles of primate brains
         1. size
         2. structure
            1. human changes in proportion to brain size
            2. a simple consequence of neoteny?
         3. development
            1. overproduction and neural pruning
            2. endogenous organization
            3. reactive organization
   2. costs associated with large brain
      1. energy -our brain takes far more than its share
         1. Falk's radiatior theory of brain evolution
      2. birth
   3. brain related human adaptations
      1. relative brain size and organization
         1. cytoarchitecture and interconnected regions
      2. cerebral specialization and handedness
      3. language specializations
      4. accelerated birth
      5. digestive tract
      6. high male parental investment
         1. protect prematurely born offspring
         2. help supply high quality omnivorous diet
