You know, I'm not sure my previous post really got the actual point across:
The human reproductive system is essentially structured to terminate fertilized eggs on a routine basis. From a certain point of view, the whole system is set up as a harsh evolutionary process. A weak and likely genetically damaged sperm will not reach the egg first, if at all. Genetic defects are detected and spontaneously aborted.
It seems difficult to reconcile those facts with the beliefs that humans (and subsequently the human reproductive system) were designed by a deity and that termination of a fertilized egg is equivalent to murder in the view of that deity.
I can think of several theological ways to resolve it, I suppose, but those theological points of view end up being the exact opposite of the views held by the anti-evolution Christian fundamentalists.
I feel a sigh coming on.
