Y'all might find this interesting. P_W, this one might bother you in the same manner it bothers me, which is why I pinged you. You might have insights into this I don't.

Didn't know this was possible. You'd think a chimerical fetus wouldn't be viable. Immune system attacking body parts, that sort of thing.

Thanks for the ping, but I'm stumped for a clever response. I wonder if her internal organs are the same as ours -- two kidneys, etc. She might have extras. Also, I wonder if this "fusing twin" thingie could be an inheritable trait, just as twins can run in families. There really could be evolutionary implications here. But basically it's just creepy.

Thanks for the ping, Junior. As I said, if it's science, religion or politics, ping away...I'm simply not interested by the endless crevo debate.

What troubles you about this condition? Is it that most of these individuals seem to be the product of IVF, and thus there are some rather snarly metaphysical questions attached?
