This work investigates the mechanisms and patterns of human migration during prehistoric eras to understand how populations expanded and interacted across global landscapes. Irving Rouse, a prominent archaeologist known for his work in Caribbean and American prehistory, utilizes archaeological evidence and cultural distribution data to construct a framework for identifying migratory movements. He argues that migration is a primary driver of cultural change and that specific material culture markers can trace these ancient human dispersals.
