There are tribes who have had plenty of blue-eyed individuals after colonization, such as the Lumbees and the Cherokees, because those tribes lived in close contact with a Caucasian community as large as their own and intermarried with them frequently.
In general, ancient and contemporary Native Americans were predicted to have intermediate/brown eyes, black hair, and intermediate/darker skin pigmentation.
18th-century reports about characteristics of Mandan lodges, religion and occasional physical features among tribal members, such as blue and grey eyes along with lighter hair coloring, stirred speculation about the possibility of pre-Columbian European contact.
Why do some indigenous people have blue eyes? It turns out that the tribe developed these piercing blue eyes as a result of a rare genetic disorder called Waardenburg syndrome.
Scientists believe that it is possible to trace all blue-eyed people back to a common ancestor, who likely had a genetic mutation that reduced the amount of melanin in the iris. Most people with blue eyes are of European descent.
Researchers have finally located the mutation that causes blue eyes, and the findings suggest that all blue-eyed humans share a single common ancestor born 6000 to 10,000 years ago. Researchers have implicated the OCA2 gene in several eye colors.
World Atlas notes that only 8% to 10% of the global population has blue eyes. Violet eyes are even rarer, but they're a bit misleading; someone with “violet” irises is usually sporting a special shade of blue.
The technologies which emerged during this time allow archaeologists and researchers to track cultural migration from the northwestern part of the Black Sea region (where the first humans with blue eyes lived) into the rest of Europe.
Estonia is the country with the most blue-eyed individuals in the world. 89% of its population have blue eyes.
There are tribes who have had plenty of blue-eyed individuals after colonization, such as the Lumbees and the Cherokees, because those tribes lived in close contact with a Caucasian community as large as their own and intermarried with them frequently.
Posted Sept. 22, 2020, 8:05 a.m. It turns out most Vikings weren't as fair-haired and blue-eyed as legend and pop culture have led people to believe. According to a new study on the DNA of over 400 Viking remains, most Vikings had dark hair and dark eyes.
Around 17 per cent of people have blue eyes, and when combined with 1-2 per cent having red hair, the odds of having both traits are around 0.17 per cent.
The four colors (black, white, yellow, and red) embody concepts such as the Four Directions, four seasons, and sacred path of both the sun and human beings. Arrangement of colors vary among the different customs of the Tribes.
A final federal census called the Dawes Rolls was taken of tribal citizens living here from 1898-1906. To be eligible for Cherokee Nation citizenship, a person must have one or more direct ancestors listed on Dawes.
The four Sacred colors, black, blue, yellow, and white have guided the Apaches in their prayers to the Great Creator - from the universe to the creations; from night to daylight.
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.
Green Eyes
Green is considered by some to be the actual rarest eye color in the world, though others would say it's been dethroned by red, violet, and grey eyes.
The Buton tribe is located exactly in the province of Southeastern Celebés (Sulawesi), and all its members have eyes of a deep blue, even more than any Nordic person. The contrast with their dark skin makes them stand out even more. One can see that their eyes are of a spectacular clear blue.
Several common variations (polymorphisms) in the OCA2 gene reduce the amount of functional P protein that is produced. Less P protein means that less melanin is present in the iris, leading to blue eyes instead of brown in people with a polymorphism in this gene.
Advantages of Blue Eyes
A big advantage to blue eyes is that research shows they might be linked to a lower risk of developing cataracts. Cataracts are clouding of the eye's lens. According to some studies, blue eyes may have evolved because these individuals were able to cope better with seasonal affective disorders.
New research shows that people with blue eyes have a single, common ancestor. Scientists have tracked down a genetic mutation which took place 6,000-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.
Likewise, two brown-eyed parents can have a child with blue eyes, although this is also uncommon.
"Originally, we all had brown eyes," said Hans Eiberg, associate professor in the Department of Cellular and Molecular Medicine at the university. "But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a 'switch,' which literally turned off the ability to produce brown eyes."
We found that green is the most popular lens colour, with brown coming in a close second, despite it being one of the most common eye colours. Although blue and hazel are seen as the most attractive eye colours for men and women they are surprisingly the least popular.
