I have a question about the ears in a way. Now I have this small hole just above my ears and its only one on each side of my head above my ears. Its the size of like a pin hole. Some people have only one. Some people don't have any. I was just wondering if anyone knew what it was OR is there for OR if there is a history to what it may have been for in the past(maybe evolutionary wise?) I appreciate any info you may have. Thanks!
