Does Geography Determine Destiny?
Stone seals from the Indus Valley were found across Mesopotamia and Mesopotamian reports indicate that they traded with “people to the east.” There is also evidence of copper and other metals appearing in the Indus Valley. All of this can lead us to believe that the people of the Indus Valley were trading with the people of Mesopotamia and perhaps even beyond. This means that not only must the people of the Indus River Valley have had enough surplus goods to trade, but, they must also have had specialization which allowed them to trade. The fact that there is a writing system, pottery, and the elaborate urban layout also lends support to the argument that they must have had specialization of labor.
