Hey Nick, remember in the paleolithic when groups didn’t trade with each other. They were mainly concerned about animals plants and other resources found nearby. As more people settled down in towns and villages trade became a more common activity.
Hey Nel, now we trade to get resources that we don't have here. People became more skilled in their crafts. This made people want to make people make more beautiful items.
Hey Nick, getting resources became a job for traders. Traders often traveled hundreds of miles in search of resources. The most popular resources were Flint and Obsidian.
The growth of trade was important because people could trade different materials that could help make their life easier and more beautiful. This also made communities grow in different areas because more and more people come looking for different materials.
