Hunter-gatherers more sophisticated than once thought?

Anthropologists uncover new theory on hunter-gatherer communities at one of North America’s largest, oldest earthen mounds, in northeastern Louisiana.The typical picture of the hunter-gatherer community is that of a small number of people wandering across the landscape, hunting for food and gathering nuts and berries. They were not complex in their political and social organization and were thought of as very simple people. But could that traditional viewpoint be completely wrong? An anthropologist at Washington University in St. Louis thinks it may be, especially for hunter-gatherer communities in Southern and Eastern parts of the United States.
