More than ten years in the research and writing, Black Superman addresses one of the most controversial debates in recent American history: Why are African Americans and other people of African descent so disproportionately represented among the greatest athletes in the world? And what are the implications if African American athletic superiority is based on genetic differences between them and other racial groups? In a persuasive and engaging mix of sports, science, and history, Black Superman argues that the athletic superiority of people of West African descent, in athletic activities involving speed and power, is based on biologically-inconsequential, environmentally-determined biochemical and biomechanical differences between them and all other racial groups and on biochemical differences between them and all other African populations.
