The author wrote this book primarily for his archaeology students, to show them how dangerous anthropological analogy is and how variable the actual practices of foragers of the recent past and today are. His survey of anthropological literature points to differences in foraging societies' patterns of diet, mobility, sharing, land tenure, exchange, gender relations, division of labour, marriage, descent and political organisation. By considering the actual, not imagined, reasons behind diverse behaviour this book argues for a revision of many archaeological models of prehistory.
