Of course they don't ask why people have unique finger prints

The passing over of amniotic fluid inside the womb, over a fetus determines fingerprint array during fetal development.

Each mother will of course...swash amniotic fluid differently over each fetus.

This has been researched and shown.

I really don't understand why your post was modded 'flaimbait'...because the chances of the situation to describe being the case are quite high. It amazes me how much 'faith' people have in these bio-engineering and pharmaceutical companies to act only the in interest of the health of humans everywhere...before profit. For goodness sake...they make money from sickness and disease ...why wouldn't they do something like this?
