This project examines how musculoskeletal attachment sites—areas where muscles connect to bone—change over time due to physical activity and behavior, leaving behind visible markers known as "entheseal changes." These changes are thought to reflect an individual's embodied lived experience, though the exact mechanisms behind their development are still debated. By studying both historic and modern documented skeletal collections, this research investigates whether entheseal changes can reveal patterns of past socioeconomic inequality and explores their potential use as forensic tools for identifying individuals based on activity-related skeletal markers.
