| Summary: | We report geometric morphometric and cladistic analyses of archaeological materials establishing early human interaction between the North American Arctic, western Canadian “Ice-Free Corridor,” and temperate North America prior to 12,000 years ago, when the Corridor is inferred to have opened after initial retreat of the continental ice sheets. The findings inform a broad range of scientists engaged in genomic, evolutionary, ecological, climatological, geological, and anthropological studies of the late Pleistocene, providing tangible evidence of human dispersal through the Americas and placing the archaeological record in the context of new genetic models chronicling the initial migration into America, as well as paleoecological interpretations of the “opening” of interior western Canada’s earliest habitable environments. |
