(lifeissues.net)
  • That is, it would be acknowledging that the human embryo and the human " baby " are the same human being and human person throughout all of his/her development. (lifeissues.net)
  • On the other hand, if by "potential" one means that the human embryo is not a human being or human person yet , but might be later once it has been born (i.e., a "baby"), then that statement is both scientifically and philosophically incorrect. (lifeissues.net)
  • Otherwise, such a treaty would not recognize the inherent human nature of the early human embryo or fetus until after birth , and thus cloning them and using them for research - both "therapeutic" and "reproductive" -- would not be banned, and women undergoing "infertility treatments" could surely be put in danger.
