Our march theme “Unique From Day One” states “from the moment of fertilization our DNA is present. The unique fingerprint we have, distinguishing us from any other human, is determined by that DNA on day one! Right from the beginning of life, you are becoming the unique, incredible, unrepeatable person that you are! Science is on the side of life! Both when life begins, and the stages of prenatal development are scientific facts. Humanity, and our uniqueness as individuals, begins at day one, at fertilization.” The American College of Pediatricians concurs with the body of scientific evidence that corroborates that a unique human life starts when the sperm and egg bind to each other in a process of fusion of their respective membranes and a single hybrid cell called a zygote, or one-cell embryo, is created.
