"It is sometimes argued that scientific discoveries show that human life exists in the fetus. Scientific studies in embryology have greatly expanded our understanding of the process of fertilization and development of the fetus and studies relating to the basic elements of life have shown that life is not only present in the fertilized egg, sperm and ova but that each cell contains elements which could conceivably constitute the beginning of a new human organism. Such studies are significant to science but only confuse the problem of defining human life."
