Unveiling The Emerald Enigma: Why Do Irish Eyes Sparkle Green?

"Why do Irish have green eyes?" is a question that has fascinated many for centuries. The answer lies in genetics and the unique history of the Irish people.

Green eyes are caused by a lack of melanin in the iris, the colored part of the eye. Melanin is a pigment that also gives skin and hair their color. People with green eyes typically have less melanin in their irises than people with brown or black eyes.

The Irish have a higher percentage of people with green eyes than any other population group in the world. This is likely due to the fact that Ireland was once home to a large population of Celts, a group of people who originated in Central Europe and who had a high frequency of green eyes.

The Celts migrated to Ireland around 400 BC, and they brought their green-eyed genes with them. Over time, these genes became more common in the Irish population, and today, about 80% of Irish people have green or hazel eyes.

Green eyes are often seen as a symbol of Irish heritage, and they are a beautiful and unique feature that sets Irish people apart from other population groups.

Why do Irish have green eyes?

The question of why Irish people have green eyes is a fascinating one that has been pondered by many for centuries. The answer lies in a combination of genetics, geography, and history.
