註釋This dissertation examines two Late Archaic (5800-3200 cal B.P.) shell rings located on St. Catherines Island, Georgia. Employing novel methods, including CT-scanning and visual analyses using computer vision, as well as traditional techniques, the histories of each ring are explored and put into a broader context of social changes occurring across the American Southeast. All along the southeastern coastline, the Late Archaic is a time of remarkable social transformations. Populated by hunter-gatherers, sea levels stabilized at or near modern levels during the Late Archaic, which allowed the development of rich estuarine ecozones. Human communities adopted less mobile strategies than their forebears and began living in centralized locales during the Late Archaic and increasingly formalized and distinct divisions between sub-regional populations also become more prevalent. Technological innovations (including pottery) became widespread, along with shifts in subsistence strategies as shellfish and plant foods, particularly tree nuts, became dietary staples for many coastal peoples.
