This afternoon we reviewed the material on pages 28-34 before moving forward. We summarized those facts relating to the Stone Age and explored several theories focusing on the evolution of man and his migration out of central Africa i.e. "The Out of Africa Theory". We discussed various reasons as to why early humans migrated and how they adapted to new environments in search of food, more favorable climate conditions or to flee predators or rival tribes. Homework is to read pages 36-39 and complete problems 1-4.
