Because blue eye color is found almost exclusively in people of European descent, Eiberg's team speculates that the mutation traces back to the Neolithic expansion, when people in the Black Sea region migrated to northern Europe 6000 to 10,000 years ago.
Origin Of Blacks With Blue Eyes
The change in eye colour only happened about 10,000 years ago due to genes mutation. This mutation that brought the rise of blue eyes affected the OCA2 gene which codes for the production of the brown pigment (melanin) in the eyes.
“The mutations responsible for blue eye colour most likely originate from the north-west part of the Black Sea region, where the great agricultural migration of the northern part of Europe took place in the Neolithic periods about 6,000 to 10,000 years ago,” the researchers report in the journal Human Genetics….
Since most Norwegians — 55 percent — have blue eyes, it is possible that the results would differ in other populations, the researchers acknowledged. “A cultural explanation is not impossible,” Dr.
Yes. I am Turkish and have blue eyes and so does more than half of my family. Blue/ green eyes are more common in some regions but can be found anywhere in Turkey. How can green-blue-eyed and blonde people be in the Middle East and Asia?
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.
While blue eyes are significantly less common than brown eyes worldwide, they are frequently found from nationalities located near the Baltic Sea in northern Europe.
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.
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. Green eyes don't possess a lot of melanin, which creates a Rayleigh scattering effect: Light gets reflected and scattered by the eyes instead of absorbed by pigment.
There are plenty of blue-eyed Asians. This probably happens when the traditional blue-eyed allele comes into a family from a (possibly very distant) European ancestor. Blue eyes then resurface in a child generations later if they inherit the allele from both parents.
Perhaps the most plausible theory is that blonde hair and blue eyes arose because of a mechanism called sex selection. This is where males and females choose as their mates those who have one unusual physical characteristic, not necessarily associated with "fitness" per se but simply something unusual.
The people of the Solomon Islands, known as Melanesian which make up 95% of the island, have naturally blonde hair and/or blue eyes.
There have been 16 genes identified that contribute to eye colour. This means that no matter what colour eyes your parents have, yours can be pretty much any colour. All races, including Caucasian, African, Asian, Pacific Islanders, Arabic, Hispanic and the Indigenous Peoples of the Americas can have green eyes.
Finland. The people of Finland have one of the highest concentrations of blond hair in the world. In large portions of Finland, 80% of the population has blond hair (and a full 89% of the population has blue eyes).
Black hair and blue eyes is a much more rare combination than is blonde hair and blue eyes. The reason why these two traits are linked is that the genes responsible for hair and eye color happen to be close together on the same chromosomes.
When broken down by gender, men ranked gray, blue, and green eyes as the most attractive, while women said they were most attracted to green, hazel, and gray eyes. Despite brown eyes ranking at the bottom of our perceived attraction scale, approximately 79% of the world's population sports melanin-rich 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.
In fact, in Ireland and Scotland, more than three-fourths of the population has blue or green eyes – 86 percent! Many factors go into having green eyes. Sixteen separate genes have been identified as contributing to eye color.
In Ireland blue eyes are most common in Connacht, where 53% people have them.
Blue eyes are most common in the UK, Ireland, Finland and Sweden. According to World Atlas, 8% - 10% of people in the world have blue eyes. Between 55% to 79% of people have brown eyes with dark brown eyes being most prominent in Africa, East Asia, and South East Asia.
Extensive research into the genetic spread across Ireland and Britain has found that we have massively underestimated Irish Viking heritage. 'How Viking are you?
Grey eyes are one of the rarest eye colors. Less than 3% of the global population has grey eyes. They're most commonly found in people of Northern and Eastern European ancestry.
The laws of genetics state that eye color is inherited as follows: If both parents have blue eyes, the children will have blue eyes. The brown eye form of the eye color gene (or allele) is dominant, whereas the blue eye allele is recessive.
