Ever since the world was introduced to Dolly, the most famous sheep in history, interest in cloning has been intense. The possibility of cloning humans has created horror, fascination, government prohibitions, publicity seekers, and inevitably, passionate arguments for and against the use of this technology. The debate does not end with human cloning. Animal experimentation including organ culture, gene transfer, and "gene targeting," perhaps to make animal organs more suitable for transplantation into humans, also raises troubling questions. In this splendid collection of essays and interviews, respected authorities ponder important issues raised by the new cloning technology. Most, though not all, of the articles focus on the ethics of human cloning. The authors are distinguished, ranging from Cardinal John O'Connor of New York, to Ian Wilmut, "creator" of Dolly, to leading ethicists and scholars. The range of opinion is wide, but invariably thoughtful, lucid, and persuasive. Should we worry about the (probably inevitable) production of human clones? The student or adult who is interested in this question could hardly do better than reading the essays in this slender book, part of the At Issue, An Opposing Viewpoint series. Also included are an excellent bibliography and a list of organizations which can be contacted by mail or Internet address for further information. Index. Biblio.
