Moore’s 1974 edition of a human embryology textbook states that development is a continuous process that begins when an ovum is fertilized by a sperm and ends at death. It is a process of change and growth that transforms the zygote, a single cell, into a multicellular adult human being.10 Moore’s 2008 edition emphasizes that development does not end at birth but extends into early adulthood.1 Professor Emeritus of Human Embryology of the University of Arizona School of Medicine, Dr. C. Ward Kischer, affirms that “Every human embryologist, worldwide, states that the life of the new individual human being begins at fertilization (conception).”
