Do you have blues eyes? (Lucky you!) Are you dating someone with blue eyes? (Even luckier!) You may think the eye color similarity is no different than dating with someone with a similar hair color or skin tone, but science just revealed that BOOM: All people with blue eyes are genetically linked. Thus, you and your blue-eyed hunny are both definitely related somehow - and even weirder, your shared relative can be narrowed down to one ancestor!
A study at University of Copenhagen found that because blue eyes are a genetic mutation — before said mutation, everyone in the world had brown eyes — everyone who has blue eyes is related.
They recruited 800 people with blue eyes and found that 99.5% (!!!!) of them had the same mutation in the gene that affects the color of their eyes. You might roll your eyes at this study and think so what? That probably means that all brown-eyed people are also related, right? But nope - it doesn't work both ways.
Only people with blue eyes all share a common ancestor, the first ancestor to ever have this genetic mutation. For people with brown eyes, there's many, many ancestors who have carried that eye color.
So who exactly is this secret relative all blue-eyed people share? Science isn't totally sure, but the oldest remains of a blue-eyed person was found in Spain. The man is about 7,000 years-old and had a combination of African and European genes. This means that different eye colors appeared in humans before different skin tones.

Uh, all PEOPLE are genetically linked.
Can you imagine being the first person with blue eyes?
I’m sure they had plenty of people of the other sex interested in them!
I recently read (here, I think) there are other Scientists! who say that ANY person can have blue eyes. Brown, etc. eyes have a structure of the eye that a layer of pigment that lies over the cornea and that layer (one might think of as impurities I say) can be removed over time by a procedure they describe.
So, my question is which is the mutation and which is the natural condition?
Well, yeah, but this concentrates on the ones with blue eyes since it is the same mutation. I knew someone would post this, but I didn’t think it would be the first! We have an early winner...
Blue-eyed ping from a hazel-eyed guy.
This article goes into the “read to make yourself dumber” file.
Thanks Pharmboy.
So, where do hazel eyes come in or green, or Grey eyes? What mutations are these?
Only people with blue eyes all share a common ancestor, the first ancestor to ever have this genetic mutation. For people with brown eyes, there's many, many ancestors who have carried that eye color... the oldest remains of a blue-eyed person was found in Spain... about 7,000 years-old and had a combination of African and European genes. This means that different eye colors appeared in humans before different skin tones.
What about the old belief that all newborns have blue eyes?
They are assuming there was only a single incidence of the "blue eyes" mutation. They have no proof of this.
We all have blue eyes beneath a melanin layer of varying opacity which creates the range of eye colors. Newborns have blue eyes, elderly people with brown eyes have been known to have them start turning blue and there is a new cosmetic procedure to break up this melanin layer to give blue eyes to anybody who wants to spend the money to have them.
Bet he was H O T!
People with blue eyes are mutants.
But being gay is a natural occurring randomization.
OK, so my dad had blue eyes and my mom had brown so not related. I have blue eyes and my wife brown so not related. My brother has brown eyes and his wife blue so not related. Or are they?
800 people from where? There are at least that many genetically linked around here from the generations that have grown up here. That's a very small sample.
