I'm surprised at how you feel you need to cling to the idea that all female animals (or some or any) have pain at birthing.
Very interesting
Well
Perhaps you guys never knew this very pregnany aspect of human reproduction . Not even suspected it.

I insist that only female people have pain at childbirth.
Not apes or elephants.
If I'm wrong then a few references from the science sources you all tell me you haunt should PROVE ME WRONG.
All chips in boys.

The hyaena makes my case. If this is all you got then there must be a fundamental difference between our women and allll the kinds of animals that give live birth. (Unles you saying chickens egg laying isn't as fun as it seems).
I also insist the hyaena is not suffering pain giving birth in any way similiar in its process to the womenfolk. There may be a 2 second yelp for a first birth rip. This doesn't count and shows desperation on your part to say this is birth pains too.

Again I say all my knowledge on human birthpain exclusity is from evolutionist premised literature.
They explain away it by saying upright walking changed this and that. Not about a bigger head but thats a good point too I guess. Though I'd take a baby head over a rhino butt anyday.
Did I hit a embarrassing nerve??
