Human diversity, with its myriad of different conditions involving biology, psychology, and social structures, remains one of the biggest challenges — and opportunities — facing the species. With many government and private firms now having diversity or equality officers, programmes or committees, it is clear that human diversity is a cornerstone of policy-making at the very highest echelons. All this points to a need for proper scientific and medical information on this topic — not soft 'politically correct' sociology.This book provides the hard facts on human similarities and differences, their causes and effects on people. It covers the whole range from normal to extreme human types, and presents — for the first time — much of the author's 25 years of original research on the subject. It can also act as a family medical guide to aspects of human function, structure and disease. It covers many human topics in a humane and understandable fashion, providing much material for information and discussion. It can be used as a handbook or textbook on human diversity, but is mainly popular science for the general public. A special feature of this book is the 140 colour photos that illustrate the diversity of human life, nearly all taken by the author himself.Given the vast nature of the subject, the book seamlessly integrates relevant data from multiple disciplines including medicine, biology, anthropology, genetics, psychology, evolution, languages, sociology, history and geography. Even controversial subjects such as race, class and culture are tackled head-on with no-nonsense scientific rigour.
