• 1. The evolutionary background; 2. Race before evolutionary theory; 3. Race after Darwin; 4. Race in the era of genetics and genomics; 5. Variation in genomes, and how humans took over the world; 6. Clustering and treeing; 7. Race in medicine and complex phenotypic studies; 8. Human adaptations; 9. Race, science and pseudoscience.

'DeSalle and Tattersall provide a brilliant and comprehensive refutation of the folk concept of human races. Anyone who thinks that there are natural categories of people that correspond to zoological subspecies will have their worldview blown to bits!'
