1. Roots of Inequality-Jared Diamond’s Theory

2. There is a starting point:  “In the 13,000 years since the end of the last Ice Age, some parts of the world developed literate industrial societies with metal tools, other parts developed only non-literate farming societies, and still others retained societies of hunter-gathers with stone tools.  Those historical inequalities have cast long shadows on the modern world…”  (13)

3. “Why did human development proceed at such different rates on different continents?
Diamond’s question was then answered:
“History followed different courses for different peoples because of difference among peoples’ environments, not because of biological differences among peoples themselves.” (25)
