This book fights the gene centric world view by explaining the reality of human diversity. Molnar challenges some of the biggest "genetic" factors that separate the human population (race, intelligence, disease). If you want to understand the difference between what society says about Genes and human variation and the reality of human diversity, read this book.
This book is FANTASTIC! I think it should be incorporated into every biology or anthropology program. Its familiar to think that Genes make you who you are, but there is so much more going on.
