This book addresses issues of continuity and change in past life-ways as well as radical shifts in techniques, innovation and achievements of the Saharan people during the Holocene period, the last 10,000 years. The project is accomplished through a series of precise case studies, each addressing a topical space-time problem. The key pre-occupation linking the case studies is a concern with the replicability of research protocols and the testability of suggested results. The anthropological perspective advocated in this book is anchored on the investigation of dynamic processes that have shaped the archaeological record and the evolution of past Saharan societies. The approach is a broad one and does not focus exclusively on any one of the many conflicting approaches currently debated by archaeologists. Theoretical issues are systematically woven with the empirical record and consistently tested, supported or refuted with hard archaeological facts.
