How do archaeologists know the village of Jarmo traded with other villages?

Answer 1

Archaeologists have discovered obsidian, seashells, and other valuable materials brought there by traders.

Answer 2

Archaeologists have found evidence of exotic goods, such as obsidian tools and shells, at the village of Jarmo that are not naturally found in the area. This suggests that trade networks were established with other villages to acquire these items, as they had to be brought from distant locations. Additionally, the presence of storage facilities and specialized craft items at Jarmo also supports the idea of economic interaction with neighboring communities.
