    • -Child (tooth eruption) "Taung Child"
    • -Deciduous(baby teeth) canines small
    • -Ape-sized brain
    • -Endocast showed brain stem position changed(foramen magnum)
  2. Piltdown Man
    • - "Discovered" in 1912
    • - Showed that "the brain led the way" in human evolution
    • - "Proved" earliest hominin was English(not African)

  7. Increase in Foraging Complexity
    • - Larger brains
    • - Long periods of juvenile development:
