A look to the future and the unprecedented dilemmas that prenatal testing raises: we can now choose who will be allowed to be members of the next generation.

Many of the primary source documents that are described in this on-air program are available at this site. These materials are mostly found via the Evidence and Community themes in the navigation bar above. All the thematic material is arranged into four chronological periods. This site also contains materials not included in the on-air programs.
