The abortion issue persists as one of the most socially divisive issues of our time. Without taking sides, the author, a well-known human embryologist, presents in clear, understandable language the embryological science that has been used to support or detract from stated positions on the issue.
Beginning with a chapter that underscores the importance of defining terms and asking incisive questions about when personhood is achieved, the text moves on to a well-illustrated summary of the important aspects of human embryological development, both normal and abnormal, as they relate to the abortion controversy. This is followed by a chapter on embryo technology, ranging from in vitro fertilization to cloning, and how these developments complicate the arguments on either side of the controversy. Closing chapters focus on the arguments used by both sides of the discussion and how these arguments are or are not supported by scientific facts. The text closes by saying that science alone cannot provide definitive support for either side of the abortion controversy and that ultimately any position on the question of abortion is based upon belief.
The text chapters are followed by an appendix that provides a detailed timeline of embryonic development from fertilization to birth, a glossary and a list of questions for discussion groups.
