How were early stone tools made, and what can they tell us about the development of human cognition? This question lies at the basis of archaeological research on human origins and evolution, and the present volume fulfils a growing need among advanced students and researchers working in this field. The individual chapters by a range of leading international scholars approach stone knapping from a multidisciplinary perspective that embraces psychology, physiology, behavioural biology and primatology as well as archaeology. The skills and behaviour of humans and their primate relatives are key parts of the enquiry. The result is a better understanding of early human engagement with the material world and the complex actions required for the creation of stone tools. The book contains many illustrations and is extensively referenced, and provides a landmark contribution in this field.
