Roger Lewin has rewritten his introduction to human evolution. This new second edition presents an up-to-the-minute survey of palaeoanthropology - the study of human origins. The subject has undergone a transformation in recent years as palaeoanthropology now embraces new approaches to answering the crucial questions of evolution. In this book, Lewin synthesizes these approaches, touching on the fields of primatology, palaeontology, palaeoecology, geology, molecular biology and archaeology. Aided by clear, informative illustrations this book offers the student of human origins a broad summary of the state of this science.
