Personally, I am obsessed with the bellybuttons of Adam and Eve. Neither had need of a navel, so why are they most often depicted with them? Here, Michelangelo clearly painted Adam’s needless navel in his Creation of Adam at the top, yet Adam’s navel appears to disappear in Michelangelo’s Creation of Eve at the bottom; Eve’s also doesn’t appear to appear.

I suppose it could be argued that Adam’s umbilical cord was directly connected to God, but still, God could have created Adam without the need of a tether.

Michelangelo, a master of the biology of the body, has some explaining to do.
