What if your ancient ancestry is hidden in your eye color? From hunter gatherers exploring the dark forests of Europe, to the seafaring expansions of the Vikings — here is what your specific eye color reveals about the ancient lineages you carry, from brown eyes to blue, gray to hazel.
But first up is green eyes. Now if your eyes are green, you possess the rarest major eye color on the planet, shared by a mere 2% of the global population. And if you look at this table, you can see how common this eye color is in parts of northwestern and northern Europe. They are especially common in regions connected to both Celtic and Norse ancestry, including Ireland, Scotland, Iceland, and parts of Scandinavia.

We know as well that the Norse-Gaels of Ireland and Scotland were a blend of Scandinavian and Celtic ancestry. And from my own anecdotal experience, I have met quite a lot of people with green eyes who have Norse-Gael surnames like MacLeod for instance, and let me know if you have green eyes below or what your eye color and ancestry is in general.
Now green eyes are thought to have emerged in prehistoric Europe. While scientists cannot identify the first green-eyed person, the genetic foundations for light eye colors were already present among some of Europe's Mesolithic hunter-gatherers more than 8,000 years ago.

We know Western Hunter Gatherers carried some of the earliest light-eye variants in Europe. Then farming populations from Anatolia mainly had brown eyes, with later Bronze Age Steppe groups adding new layers of ancestry, yet again they mainly had brown eyes. Over thousands of years, these populations blended, creating the range of European eye colours we see today — including green.

And from a genetic perspective, green eyes represent a perfect middle ground. They occur when the iris contains a low-to-moderate amount of brown melanin, paired with a high concentration of a yellowish, light-brown pigment called lipochrome. When the structural blue scattering of the clear stroma mixes with this yellowish layer, the human eye perceives it as a vivid green. So if you have green eyes, your DNA likely harbours a strong connection to the ancient Atlantic façade and Northwestern Europe, echoing the complex mixing of ancient European ancestors, Celtic tribes and Norse warriors, although not exclusively ofcourse.

Now next up is brown eyes, the most popular eye color in the world, found in 70-80% of people.
