The third edition of this text presents human evolution in the context of the behavioural ecology of a large-bodied, large-brained mammal. The author shows how developments in the study of life history theory and ecological influences on social structure can be applied to species long extinct; thus bringing this text completely up to date. Whilst retaining the basic structure of earlier editions; the book integrates anatomy and behaviour as never before, updates the latest evidence on "mitochondrial Eve", and has a greatly expanded glossary.
