When Does Life Begin?

Chapter 29: When Does Life Begin? - Answers in Genesis: Even though the names arbitrarily change throughout this process and certain milestones in development are evident, the process set in motion at the moment of conception is a continuous chain of events. In this sequence, groups of cells multiply and develop into specific body parts with amazing precision and a remarkably low rate of error, considering the complexity of changes that must occur. However, at no time in this process is there a scientific point at which the developing individual clearly “becomes a person,” any more than a baby becomes more human when it walks, talks, or is weaned. These milestones in zygote, blastocyst, embryonic, and fetal development are simply descriptions of anatomy, not hurdles met in the test of humanness. From a scientific point of view, the words are arbitrary and purely descriptive.
