Of maize and men: reproductive control and the threat to genetic diversity

The genetic diversity argument (GDA) is one of the most commonly voiced objections to advances in reproductive and genetic technologies. According to the argument, scientific and technological developments in the realm of genetics and human reproduction will lead to lower genetic diversity, which will threaten the health and survivability of the human population. This discussion explicates and analyzes the GDA and challenges its empirical assumptions. It also discusses the possible significance of the GDA in our overall thinking about genetics and human reproduction and examines two proposals for preserving "useful" genes.
