In making interpretations about the lithic technological connections between late Pleistocene-aged Northeastern Asian and North American sites, archaeologists have traditionally employed comparisons of tool assemblages or simple bounding box metrics of formed tools. The hypothesis that a strong connection will be seen between early lithic technologies of Beringia and the Clovis Paleoindian Tradition of North America can be rejected due to the fact that nonfluted technologies of the Nenana Complex are earliest and because Alaskan fluted projectile point technology is younger than elsewhere in North America. While some archaeologists have argued that an ancestor-descendant evolutionary relationship may have existed between the Nenana and Clovis technological complexes, this conclusion is based on qualitative pattern matching of tool categories and comparisons of two-dimensional object outlines and requires more rigorous evaluation. In contrast, close morphological similarities are identified between nonfluted stemmed projectile point technologies of western Beringia and Western Stemmed Tradition projectile points from the Pacific Northwest, also based on comparisons of two-dimensional artifact forms. Here, we discuss the use of digital scanning and 3D geometric morphometrics to conduct a more comprehensive approach to evaluating the technological connections between late Pleistocene-aged lithic technologies between Western and Eastern Beringia and the Pacific Northwest of North America.
