The ghost of eugenics recurs in many guises during debates and controversies about intelligence testing, genetic screening, prenatal diagnosis, gene therapy, new reproductive strategies, and uses of our genomic information. Carlson discusses the history of humanity in this arena with an exploration of the future of genetics that is based on new technologies and application of the Human Genome Project findings.
