What ways did community's interact with each other around 12000 BCE?

Answer 1

They didn't have villages but were hunter-gathers. Their entire day is spent in finding food. The men in hunting animals of one sort or another, the women in finding berries and starchy roots and the younger children usually help by finding and bringing water back to camp. These groups were made of extended families. When food was no long easy to find, they would leave and follow the herds of grazing animals that also were looking for new supplies of food. Sometimes they ran across other groups and perhaps exchanged goods like hides and even arranged marriages. But this didn't happen very often. There were not many humans 14,000 years ago. If the group got too large it couldn't support itself and some would start another group.

Answer 2

Around 12,000 BCE, communities interacted through trade, social gatherings, and possibly warfare. Trade networks allowed for the exchange of goods and ideas between different groups, while social gatherings such as festivals or ceremonies provided opportunities for cooperation and cultural exchange. Warfare may have occurred as communities competed for resources or territory.
