• 1492
    • Caribbean Sea
  • By 1700
    • Most of South America
    • Mexico
    • Florida, California
  • How did they do it?
    • Case Study
      • "Peru" (1535-1717) means Spanish-speaking South America (not Brazil)
  • Spanish vs. South America (Incans)
    • Spanish side

    • Biodiversity and geographical difference
  • European Advantages
    • Military Tech
    • Immunities to disease
    • How did they get these advantages?
      • Biodiversity in Eurasia
        • Biodiversity means that there are more kinds of plants
        • Also means more animals
  • Effect of biodiversity (all of this leads to technology!)
    • Better food supply
    • Higher population
    • Specialization of labor
  • Geography
    • Boundaries ran east and west
    • Plants and animals travel east to west
    • Biology has a tendency to travel east and west so Eurasia had a better chance
    • The Americas were north-south continents so it's harder for things to travel
    • Technology and disease also spread east to west
