Presidential candidate Mitt Romney was recently seen assuring his supporters of his anti-abortion stance with the standard line: it’s a “biological fact” that the fertilized egg is alive and that life begins at the moment of conception.
Sorry, Mitt, but when your mama or your daddy told you the “facts of life,” they got them wrong. Let’s get the biology straight, OK?
Life doesn’t stop and start. In all living organisms that reproduce sexually, life continues through the stages of a sexual cycle. Some cells in our ovaries or testes carry out a special kind of cell division (meiosis) to produce egg and sperm cells; and under the right conditions a sperm and an egg combine to produce a zygote, which then normally develops into a mature person who produces more sperm or eggs.
