Synopsis: From front flap: "Together, these two well-known writers have managed to explain in simple terms the very complex subject of race, discussion in detail genes, cells, chromosomes and blood. [...] When the reader has finished the book (which is fun to read and full of touches of wit in addition to being informative), many of his preconceived notions about race will be changed. He will know why he is as he is, why others are as they are, how the differences came about and, most important of all, he will be convinced that there is no such thing as a 'superior race.'"
