Professors of Anthropology Charlotte Beck and Tom Jones presented a paper titled "A Case of Extinction in Paleoindian Lithic Technology" at the 74th Society for American Archaeology Meeting in Atlanta on April 23. The paper is a continuation of Beck and Jones's research on the earliest colonists of North America and discusses the ultimate disappearance of a particular technology used initially by these early colonists. The paper was presented in a symposium co-organized by Nathan Goodale with William Andrefsky Jr. (Washington State University) titled Lithic Technological Systems: Evolutionary Approaches to Understanding Stone Tools as a Byproduct of Human Behavior.
