    • BIG HISTORY By Cruz Major
    • The Day the Universe Changed
      • The nature of history is constantly changing
      • Every generation is taught history different yet the main themes and concepts remain the same
    • The Journey of Man
      • Spencer Wells traces human evolution back to our first ancestors
      • Evidence claims that the first humans derived from Africa
      • DNA samples from people around the world show that all living people are descendants of African ancestors
    • The Journey of Man
      • Spencer Wells attempts to prove his theory that that the global migration of man began with a tribe of Africans who left their home some 60,000 years ago
      • He explains how he traced the exodus of modern humans from Africa by analyzing genetic changes in DNA
    • Catastrophe
      • Key’s thesis is that a global climatic catastrophe in A.D. 535 to 536, a volcanic eruption, was the decisive factor that transformed the Ancient World into the Medieval Era
      • Writings from the time indicate a natural disaster in that year blocked the sun causing famine, flooding, and the plague
    • Catastrophe
      • Keys used samples from trees, ice, lakes as well as documents of ancient chroniclers to provide evidence of his thesis
    • The World and Trade
      • The experience of exploration is worth more than theory
      • The world beyond Europe was not quiet and sleepy in 1492
      • Exploration and activity was already being done by different peoples across the globe
    • The World and Trade
      • The world was separated into different regions that rarely came into contact with each other
      • Although the Norse had reached the Western Hemisphere before the Spanish, Columbus's voyages had a much longer lasting impact
    • Guns, Germs and Steel
      • Why did Europeans and Asians, come to control most of the world, rather than Africans, Native Americans or other people?
      • Jared Diamond’s theory is that there is no superior class of people, rather just bad luck
    • Guns, Germs and Steel
      • Europeans and Asians achieved dominance because of their ability to domesticate animals due to the abundance of plants
      • The location of Europe and Asia made migration and the transfer of animals and goods much easier
    • Guns, Germs and Steel
      • An abundance of food made it so that people could focus their time in other things rather than farming
      • For example a military
      • Places that were not fertile had no cavalry or form of defense because they could not allocate resources to do so
