Archaeological investigations conducted in the late 1980s at Fish Slough Cave, Owens Valley, California recovered over 300 well-preserved human coprolites. When the nutritional profile of the diet inferred from coprolite analysis was compared against optimal foraging model predictions, based on energetic returns, the diet was considered to be deficient. However, when the same data were considered from a nutritional ecological perspective using macronutrients (e.g., water, protein, fat and...

Nutrition has exerted a powerful influence on human evolution and history, and continues to play a central role in global challenges such as food security and obesity. However, the complexity of nutrition presents considerable challenges for researchers to unravel its grip on human affairs. In this talk I will introduce an approach called nutritional geometry that has been developed to aid this process. Nutritional geometry differs from conventional nutritional models in acknowledging that...

Shells are especially visible in the archaeological record of Central California. They comprise much of the midden in the large shellmounds that once lined San Francisco Bay. However, shells are also present in many inland sites, though they were collected from the Bay and hauled many kilometers inland. Seasonality reconstructions using oxygen stable isotopes show that shells on the Bay were typically harvested in two seasons, winter and summer, but inland sites contain shells from just winter....
