Fun fact I learned is that dimples are a dominant gene. If one parent has a dimple, they say its guaranteed that the child will have a dimple. So, just think…some time in the future…almost all of us will have dimples and then smooth cheeks will be considered cute and worthy of a cheek pinch!
Well, it inspired me to find out what else is dominant and I don’t understand what mother nature has in mind for the future of appendages.
