  • (final thought) why can't the cortex just act its age?
  • complexification
  • a brief tour of brain development
  • stages
  • consequences

  • the biological profile
  • 2 side topics
  • a key question
  • a sledgehammer
  • culture
  • 9 long months

  • genes - from the bottom up
  • genes - from the top down (behavior genetics)
  • genes vs behaviors
  • definitions, similarities, differences

  • pastoralists vs southerners
  • stratified vs egalitarian
  • populations: size, density, heterogeneity
  • residues of cultural crises

  • evolution can shape behavior
  • demise of group selection
  • individual selection
  • kin selection
  • reciprocal altruism
  • standing on 3 legs
  • multilevel selection
  • and us (humans)
  • where are the genes?
  • is evolutionary change continuous & gradual?
  • is everything adaptive?
  • strength of us vs them
  • us
  • those thems
