blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family.

Your eye color has everything to do with your genetics, and if you're blue eyed, you can probably figure out who's a distant relative just by looking at them. It could be said that all eyes are the same color. That’s because the pigment that gives our eyes color, melanin, is naturally brown. In fact, originally, “we all had brown eyes,” a professor from the University of Copenhagen, Hans Rudolf Litchoff Eiberg, PhD, told Science Daily. Somewhere along the way, however, someone was born with a genetic mutation, Dr. Eiberg explains. That genetic mutation limited the amount of melanin the person’s eyes could produce, with the visual effect being that the eyes appeared blue, rather than brown. Interesting, you might be thinking, but what do blue eyes genetics have to do with me? Well, the fact that all (so-called!) blue eyes descend from a single genetic mutation means that every single person on the planet with blue eyes descended from one common ancestor. In fact, a team of geneticists at the University of Copenhagen actually traced that mutation all the way back to a single Danish family. “By linkage analysis…we fine-mapped the blue-eye color,” Dr. Eiberg’s team reported in the journal, Human Genetics. Through that analysis, it was discovered that an identifiable group of genes had been inherited together from one single parent—the scientific word for a group of genes inherited together from a single parent is “haplotype.” The identified haplotype was common not just among 155 blue-eyed individuals from Denmark, but also five blue-eyed individuals from Turkey, and two blue-eyed individuals from Jordan. In addition to haplotype mapping, Dr. Eiberg’s team conducted mitochondrial DNA analysis, which looks at patterns of genetic mutation to trace maternal ancestry back hundreds of thousands of years. “Variation in the color of the eyes from brown to green can all be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes,” Dr. Eiberg notes. “From this we can conclude that all blue-eyed individuals are linked to the same ancestor…They have all inherited the same switch at exactly the same spot in their DNA.” Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production.

In case you were planning to decorate your impending grandbaby’s nursery to match the color of their eyes, be prepared to be disappointed. It is impossible to predict what color their orbs will be. “There are several different genes involved, which we’re just beginning to learn about and understand,” Kaplan explains. HERC2, for example, is a gene that turns the OCA2 gene on or off as needed. Different variations of it can cause the OCA2 gene to produce less melanin, which leads to lighter-colored eyes. There are at least eight other genes that influence eye color. In the meantime, you can take comfort in the fact that your own individual eye color is like your fingerprints: something that is unique only to you. Brown eyes are the most common: Over half the people in the world have them, according to the AAO. In fact, about 10,000 years ago, all humans had brown eyes. Scientists speculate that their elevated levels of melanin helped protect people from the sun’s damaging rays. But as people moved from the sweltering climates of Africa and Asia to the cooler environments of Europe, there was less need for this protection. At some point in history, as humans migrated north, a gene mutation occurred to reduce melanin production, says Kaplan. When the eyes have less melanin, they absorb less light. That means more light is scattered out from the iris, or colored part of the eye, which reflects off the surroundings. Eyes with the smallest amount of melanin in them will appear blue, while those with a little more melanin will appear green or hazel.
