Blaschko lines, invisible stripe patterns on everyone’s skin, can sometimes produce different amounts of melanin. Birds may also be able to see them, even if we can’t.

      So, when asked to identify my race, I can no longer check the box for “white”. They need one stating “It’s complicated.”

      *Blaschko’s lines, also called the lines of Blaschko, are lines of normal cell development in the skin. These lines are only visible in those with a mosaic[1][2][3] skin condition or in chimeras where different cell lines contain different genes.[4] These lines may express different amounts of melanin,[5] or become visible due to a differing susceptibility to disease. In such individuals, they can become apparent as whorls, patches, streaks or lines in a linear or segmental distribution over the skin. They follow a V shape over the back, S-shaped whirls over the chest and sides, and wavy shapes on the head.[6][7] Not all mosaic skin conditions follow Blaschko’s lines.[8]*

    3. Now imagining the patterning of someone with visible Blaschko lines plus a wicked set of Lichtenberg figures.

      Is this how Crows allegedly recognize humans that were mean to them years ago?
