For decades medical textbooks have presented the consensus view that biological human life begins at conception. For example, textbook authors Moore and Persaud explain that the very first cell resulting from fertilization “mark[s] the beginning of each of us as a unique individual.” In addition, William Larsen’s textbook on embryology explains that the moment of fertilization “initiate[s] the embryonic development of a new individual.” O’Rahilly and Muller also agree in their textbook that, at the moment of fertilization, “a new genetically distinct human organism is formed.”.
Currently in the United States, there are over 500,000 frozen embryos, or “snowflake babies,” waiting for their chance to really live. Did you know that you can adopt a child even before they enter the womb?
