Missing the point about embryos Christopher Barbara (May 6) completely misses the point made by Ivan Padovani’s note which highlighted the incontestable fact that every human adult was at one point a zygote. Whether we should casually call the early embryo a “miniature baby” or not, no biologist could, or would, deny that she was a zygote at the earliest instant of her life. I was once a zygote, even you, the reader of this letter was once a zygote. The argument for abortion is not a scientific one but an ideological one which is why Barbara rapidly shifts the line of thought away from science to one of social policy and women’s health.
