Using stable isotope analysis to obtain dietary profiles from old hair
Stable isotope composition of human tissue reflects that of foods consumed, and can provide information about diet independent of artifactual remains. Here we refine and test this method by analyzing nitrogen (delta(15)N) and carbon (delta(13)C) isotope ratios in historic North American Plains Indians hair. Gas-source isotope-ratio mass spectrometry provides high-precision data for both delta(15)N and delta(13)C (+/-0.2 per thousand, 1 sigma) in …
Pleistocene migration routes into the Americas
Theories about the routes and timing of human entry into the Americas during the Late Pleistocene usually involve models of lowered sea levels and ice‐free land in Beringia, supported by locations and dates of archeological sites in Northeastern Asia and Northwestern America. Recently, paleoecological reconstructions made possible by advances in geochronology and climatology have received attention. Now morphological adaptations and environmental…
