When do you become a human being?

[Benton]

To the OP:
I think it differs in every case. I don't think you can set a date and say "all clusters of cells staying together at this point will be a real human!" Some babies are born a couple weeks early and don't make it; some are born months early and battle through.

My opinion on the subject doesn't matter a whole lot. I don't like it, but I'm not a woman and, more importantly, not a doctor. I think we have a lot of well intended folks on both sides who have good arguments but woefully few medical degrees. I don't know why the belief of a carpet layer from Pittsburgh should have as much bearing on the viability of an embryo as a medical doctor from Denver.
