In this novel examination of the issue of abortion, the authors offer a primer in the biological aspects of fetal development and its impact on the abortion controversy. Although purely scientific study cannot offer a universal solution to the issue of abortion, nor can a purely political or moral response be fully informed without the benefit of the latest scientific knowledge.Reviewing the latest developments in molecular biology, evolutionary biology, embryology, and neurophysiology, the authors reveal a surprising agreement of scientific opinion on when 'humanness' begins: with the development of a highly developed cerebral cortex. It is on this issue that the authors focus with sensitivity to the myriad of ethical and religious arguments that surround it.
