| Summary: | Abstract With the exception of few studies, occlusal microwear of pre‐agricultural modern humans has not been documented. In this study, microwear fabrics of samples from seven historic/prehistoric hunter‐gatherer populations with known and diverse dietary habits, representing mostly meat‐eaters from different environments, arctic/tundra (Tigara from Point Hope), cold‐steppe (Fuegians) and Mediterranean (Chumash), and mixed‐diet hunter‐gatherers from tropical climates (Andamanese and Khoe‐San from Matjes River, Riet River, and Oakhurst Shelter), were analysed to better understand how dietary differences affect microwear in these groups and to establish a reasonable comparative database for interpreting fossil hominins microwear. Significant microwear differences, related to diet and food preparation techniques, between the meat‐eaters and mixed‐diet hunter‐gatherers were detected. Finer scale differences within each of these dietary categories were also observed. Ethnographic accounts indicate that the Tigara and Andamanese ingested hard particles attached to their food as a result of their food preparation techniques; their microwear fabrics also reflect highly abrasive diets. On the other hand, as expected, the microwear signatures of the Chumash and Fuegians indicate a diet low in abrasives, reflecting their almost exclusive reliance on marine meat for subsistence and the low amounts of extraneous particles attached to this meat. The mixed‐diet Khoe‐San occupy an intermediate position between the Tigara and Andamanese on the one hand, and the Chumash and Fuegians on the other, with regard to the level of abrasives ingested. The Khoe‐San ate large amounts of hard plants, most likely responsible for abrading their enamel surface. Copyright © 2008 John Wiley & Sons, Ltd. |
