Eli5 , Birthmarks



I’ve always been told a birthmark is the scar where we died from an injury in previous life, I believe to be an old wives tail. But what is the reasoning for having a birth mark?

In: Biology

It’s just a genetic mutation that doesn’t hurt reproduction. Birth marks often run in families. There is no “reason” to have it. Think of it like hair or eye color. The reason these can vary from person to person is millenia of genetic mutation.
