A great deal of public excitement and controversy has been associated with advances in gene technology, especially the idea that humans could be experimentally "enhanced." However, based on the recent history of transgenic experiments in animals, the prospects are much less rosy than portrayed, and even successful efforts could not affect human evolution. These realities should temper unduly restrictive legislation that could impede the course of scientific progress.
