“The mother and baby are separate individuals from conception.”

“The birth of a human really occurs at the moment the mother’s egg cell is fertilized by one of the father’s sperm cells, that is, at conception.”

Life magazine, The Drama of Life Before Birth

“It is scientifically correct to say that an individual human life begins at conception.”

Professor M. Matthews-Roth, Harvard University Medical School
