Prof. Diamond has an unparalleled expertise in anthropological research and the interaction between societal and political factors and environmental and evolutionary changes. That combined with his lucid writing style makes this a great book.Don't be distracted by the sensational title; this book is an impressive resource of research on societies ancient and present and the compilation and distillation of this data is remarkable.However you might find yourself disagreeing with some conclusions drawn from this data. That I suppose is what a good book is all about.
