The exact moment of the beginning of personhood and of the human body is at the moment of conception.Dr. McCarthy de Mere, a medical doctor and law professor at the University of Tennessee http://prolife.com/FETALDEV.html
By all the criteria of modern molecular biology, life is present from the moment of conception.(Dr. Hymie Gordon, Chairman of the Department of Genetics at the Mayo Clinic) http://prolife.com/FETALDEV.html
Statistics show that a soldier's chances of survival in the front lines of combat are greater than the chances of an unborn child avoiding abortion. What should be the safest place to live in America - a mother's womb - is now the most dangerous place.
Before Roe v. Wade legalized abortion, all science texts taught the biological truism that the life of any individual of any species begins at conception, when sperm and ovum unite to create a new being with its own complete and unique genetic code, distinct from both father and mother. All growth and development from then on are a matter of degree, a gradual unfolding of what is already there. There is no specific or distinct point in our development when we become human. (What were we before that? Birds?) Only when abortion became legal did the science textbooks change their language and cease teaching this truism-not became of any new science but because of a new politics.Catholic Christianity (234-235)
