"With examples replete from Africa and especially South Africa, Wilmot James draws on established biological science to tell some compelling stories about the genome, why we have different skin colours, how blood tells a special story of human history, why the brain likes music, how smell works, the nature of rock art, why kids love bugs and the teaching of evolution. James gives an account of a great South African scientist called Eddie Roux who was known more for his politics, and of an extraordinary naturalist Eugene Marais who became known more for his Afrikaans poetry. The title is based on the fact that there is one unified science with extraordinary powers of interpretation. The modern scientific discipline of genetics has in recent years helped us to understand the nature of humanity, both biologically and behaviourally, and Wilmot James has played a key role in promoting a popular understanding of it. A sociologist by training, Wilmot James moved over to genetics through his association with the Africa Genome Education Institute, of which he was founder and director. He writes fluently and convincingly and is spectacularly well-read in subjects ranging from biochemistry to music to literature and anthropology"--Cover.
