Because modern-day hunter-gatherers in Africa live in egalitarian bands that constantly move from place to place, archaeologists assumed that Native American hunter-gatherers must also have done so. Discovering the Louisiana mounds upset this view: they suggest that at least some early Indians were stay-at-homes. More important, they testify to levels of public authority and civic organization rarely associated with nomads. Building a ring of mounds with baskets or deerskins full of dirt is a long-term enterprise.
