Cloning may solve, once and for all, the problem of rejection that bedevils transplant surgery. Perhaps it even holds the secret of eternal life. But plans to clone humans have triggered an international storm of protest. Scientists including Ian Wilmut, politicians from left and right, and theologians from almost all religions find the idea not just unsavory, but abhorrent. Starting with the biology and building up the scientific background step by step, this book provides the perfect guide to the moral labyrinth that surrounds the cloning debate.
