    Faces are really the only identifying feature of our bodies that’s genetic.

      But why does our fingerprint grow back the same way when we damage our outer skin layer on our fingers? Or does it not?

        Because it’s just the outer layer, and the print is still there. Your new outer skin is just the old under layer.

        If you damage your skin enough to remove the fingerprint, it doesn’t grow back. There are lots of people without fingerprints due to the types of work they do

        They do, but they also might not.

        The part of your skin that actually causes your fingerprint is relatively deep into your skin. So it’d need to be a pretty serious injury to permanently change your fingerprint at all.
