"Genetic Turning Points is an outstanding study of the problem of genetic engineering and related ethical issues. It addresses difficult and sometimes technical matters in a style that is both clear and scholarly, and it provides valuable insights into issues that are being thrust to the fore by scientific progress. Genes store the directions for all life on earth. If you want to know where we might be going, read this book. It is a road map that can save you from many ill-fated journeys."--William R. Shea.
