Exploring Ancient Dental Calculus

The video explores the significance of dental plaque in understanding human health evolution. An archeological geneticist discusses how dental calculus, a fossilized form of plaque, provides insights into ancient diets, diseases, and immune responses. By applying genetic and proteomic technologies, researchers can study the dynamic interplay between diet, infection, and immunity over thousands of years. This research helps reconstruct the evolutionary history of human health and disease, offering a holistic approach to understanding modern health challenges.
