Human genome diversity: what about the other human genome project?

Although the Human Genome Project has been successful, the Human Genome Diversity Project, proposed in 1991, has so far failed to thrive. One of the main values in studying the human genome, however, will come from examining its variations and their effects. To do that in a systematic way, an active Human Genome Diversity Project, or something very similar, will ultimately prove vital. Such an effort will confront difficult ethical and political issues; this article reviews those issues and tries to show how they might be overcome.
