Beyond humanity?

de Allen E. Buchanan

"This book examines the ethical controversy surrounding biomedical enhancement: the use of biotechnologies to improve normal human capacities and characteristics. It deflates the heated rhetoric of the debate and, unlike other treatment of the topic, is informed by an understanding of evolutionary biology. The book debunks the idea that the natural is always good, and explains why and how we might need to change human nature"--Publisher description.
