Preparation and characterization of bone and tooth collagen for isotopic analysis
Abstract Criteria are presented for the identification of diagenetic alteration of carbon and nitrogen isotope ratios of bone and tooth collagen prepared by a widely used method. Measurements ofExpand

Experimental Evidence for the Relationship of the Carbon Isotope Ratios of Whole Diet and Dietary Protein to Those of Bone Collagen and Carbonate
The use of stable carbon isotopes for diet reconstruction is predicated on the assumption that you are what you eat. In other words, the carbon isotopic composition of animal tissues is assumed to beExpand

Chronology of the Later Stone Age and Food Production in East Africa
Abstract Evidence from several archaeological sites in sub-Saharan Africa suggests that the transition to modern human technology, marked by the change from the Middle to the Later Stone Age (LSA),Expand

Paleolithic Technology and Human Evolution
Human biological and cultural evolution are closely linked to technological innovations. Direct evidence for tool manufacture and use is absent before 2.5 million years ago (Ma), so reconstructionsExpand

Stable isotopic analysis of human diet in the Marianas Archipelago, western Pacific.
Proportions of marine vs. terrestrial resources in prehistoric human diets in the southern Mariana Islands (Guam, Rota, Saipan), Micronesia, have been estimated by analysis of stable isotope ratiosExpand

Effects of diet, climate and physiology on nitrogen isotope abundances in terrestrial foodwebs
Abstract Variations in nitrogen isotope ratios in terrestrial foodwebs are described, and alternative models for variation in the enrichment between trophic levels are evaluated. Nitrogen isotopeExpand

Systematic Butchery by Plio/Pleistocene Hominids at Olduvai Gorge, Tanzania [and Comments and Reply]
Human origins research by archaeologists has expanded the evidence of the diet and subsistence activities of ancient hominids. We examine an important component of that evidence, theExpand

The "Weak Garden of Eden" model for the origin and dispersal of modern humans (Harpending et al., 1993) posits that modern humans spread into separate regions from a restricted source, around 100 kaExpand

Stable carbon isotopic evidence for differences in the dietary origin of bone cholesterol, collagen and apatite: implications for their use in palaeodietary reconstruction
the narrow range of variation observed in apatite-to-cholesterol spacings ( 13 Capat-bchol) suggests that cholesterol 13 C values can potentially also be used as an independent test for the isotopicExpand
