<p>My research examines health and disease in prehistoric populations through their skeletal remains. I am specifically interested in understanding prehistoric human adaptations in desert ecosystems and the role local resources play in the adoption of agriculture and their impact on health. Current projects involve the excavation and analysis of the earliest farmers in the Sonoran Desert and of incipient agriculturalists in the Atacama Desert, along the northern coast of Chile.</p><p>The development and rapid spread of agriculture among prehistoric human populations throughout the globe catapulted human cultural evolution far beyond those accomplishments of the previous four million years of biological evolution. The transition from a mobile food foraging lifestyle to large permanent settlements had serious effects on the health of human beings. Increased population densities and contact with waste fostered the spread of bacterial and viral diseases. Close contact with domesticated animals led to the development of zoonoses in humans such as anthrax and tuberculosis. A decrease in dietary breadth and the limited nutrition of domesticated cultigens led to nutritional deficiencies among young and old. In addition, the focused consumption of highly processed carbohydrates led to progressive deteriorations in dental health, resulting in more cavities and tooth loss among agricultural groups. In order to understand the origin and direction of human diseases (past and present), it is important to frame them in terms of their dynamic relationship between human evolutionary biology, human behaviors, and environment.</p>
