Biology has been advancing with explosive pace over the last few years and in so doing has raised a host of ethical issues. This book, aimed at the general reader, reviews the major advances of recent years in biology and medicine and explores their ethical implications. From birth to death the reader is taken on a tour of human biology - covering genetics, reproduction, development, transplantation, aging, dying and also the use of animals in research and the impact of human populations on this planet. In each chapter there is a sketch of a field's most recent scientific advances, combined with discussions of the ethical and moral principles and implications for social frameworks and public policy raised by those advances. Anybody interested or concerned about the ethical dilemmas caused by advances in science and medicine should read this book.
