Stone tool analysis is the study of ancient tools made from stone, which were used by early humans and other hominins. Researchers examine these tools to understand their shapes, sizes, and manufacturing techniques. This analysis helps archaeologists learn about the behaviors, cultures, and environments of prehistoric peoples. By classifying tools into categories, such as flakes, cores, and blades, scientists can infer how they were used for tasks like cutting, scraping, or hunting. This information contributes to our knowledge of human evolution and the development of technology over time, revealing insights into the lives of our ancestors.
