When people think about Paul Newman, speaking generally anyway, the first thing they think about is his eyes. Same goes for Ed Harris, Frank Sinatra, and a number of the other famous men and women who spent their careers in front of the camera. The funny thing about blue eyes is that they are considered a genetic mutation. Somewhere between 6,000 and 10,000 years ago (not to be vague), everyone's eyes were brown everywhere in the world. Until. There was a genetic mutation that affected the OCA2 gene in someone somewhere that limited the amount of melanin in their eyes.
Melanin is a type of pigment in the eyes' iris that determines eye color. The more melanin, the browner. The less melanin the more likelihood of blue, green or hazel eyes. But it likely started with one person way back when. Which means that, if you were born with blue eyes, somewhere down the line you are related to Paul Newman. Think about that!
