I'm glad you elaborated on the original post's mention of fingerprints because that caught my attention too! It is cool to learn to the evolutionary advantage (grasping leaves easier).
In one of my anatomy classes, my teacher told us that fingerprints are formed when a developing fetus rubs the developing fingers against the wall of the uterus. The random rubbing patterns create grooves in the skin, as the skin grows. I can't site a source here because my teacher told us that in class. I haven't looked it up to fact-check since, but I'm sure it holds some weight!
I love this Linda - I love that our individuality is a by product of such co.intimacy - the stroking between self and self maker. we often got so judgmental for being needy for not being wholey independent and so I just love this!! thankyou
so even though there is no sited source - this gets my vote!:))
I love this fact, too!
So in theory, when I press my face against my pregnant girlfriends belly and squish her belly (mommy), and I can feel her pushing against (the baby) me through mommy's belly, I could actually be helping shape those fingerprints by changing the shape of the uterus when I press against it and she reaches out to touch me? Because the baby definitely responds to me even though she is still inside mommy's belly. That's an awesome fact, and touches me just a little, as I am sooo excited about my first baby on the way!!! Thanks for sharing!!!
