چکیده

Analyses of fluted point technology and Paleoindian technological risk have contributed to our understanding of human adaptation across North America in the late Pleistocene and early Holocene. However, poor chronological control has dissuaded similar studies of fluted points found in Alaska and northern Yukon and our understanding of their adaptive role in early arctic adaptations remains unclear. Two new archeological sites have provided reliable radiocarbon data and for the first time, a comprehensive analysis of northern fluted points is possible. Here, technological and morphological analyses of northern fluted points are presented, including variables statistically evaluated and compared to a collection of fluted Folsom artifacts serving as a reference. Variation in tool shape was measured using geometric morphometrics, and a new approach to landmark placement designed to characterize basal morphology and allow the analysis to include tool fragments is presented. Results confirm that northern fluted points represent a cohesive technological strategy and are used to formulate hypotheses suggesting its service as a risk-management system promoting ease-ofreplacement-after-failure to offset transport costs and reduce risk during long-distance travel.

The effect of environmental factors on the location of ancient sites around the ancient northern lakes of the desert plain (Holocene)

Introduction Site selection of human habitats in pre-historic times, unlike the current periods, has been strongly influenced by natural factors. Studies may be focused on three areas including paleoclimate, paleogeomorphology and archeology in order to identify environmental factors affecting primary habitats. Based on studies, most of the ancient lakes in central Iran were formed during the Q...
